Comprehensive Analysis of the C Engine and Its Development Challenges

the boring diary okay

uh a second I think there are some issues yes so we are good to go discuss engine

issue and uh ual G Namaste and we will wait 2 minutes before we start so that some more people can join in if uh if

anyone is going to join anyways so first thing first to everyone joining now uh thank you for coming I hope you will

like this video if if you are not subscribed Please Subscribe K it takes a lot of effort to create this slides and

uh to bring you uh this level of analysis and other than that if somebody is watching this live after uh this

video is or this live is over uh still uh please subscribe and share the video like the video that will be very

helpful so everybody I I hope you all are doing well 20 25 seconds start video

presentation being said that uh we will first go on to discuss why we we are uh doing this uh session so let me share my

screen [Music] yes I will I will start the presentation

now so yeah discuss what are the what are the knowledge you will be getting today from

this session uh first is that we we will discuss why the this session the context of this session then we will get into

the technical comp comparison of the C engine or

compare existing existing four four 4.5 generation G aircraft say

then we will get into the invest investment comparison now uh there is no the thing is there are some Kats here

but still the investment gone into the R&D of these engines need to be studied uh then we will get into the year-wise

Improvement in the C engine and with the that will uh uh that will create a question in your mind that

what exactly do we want next is the next is the technological bottlenecks that we will be discussing uh in in great detail

and we will also discuss the uh discuss the uh the testing facilities that have been uh created in India and what are

what are the gaps there and next is the uh what are the possible way out of this uh bottlenecks since we are desperately

in need of an engine and next is next point is that who is responsible for this lack of for for sightedness so the

context of the discussion LC Mar [Music]

the the C engine was fundamentally fundamentally conceived as an engine that will be used as as a uh

as a primary engine for the LCA program but it did not uh uh did not come out to be U as well as expected the fundamental

reason for this was uh the uh I don't know if you people are aware or not but when the LCA Mark 1A program was being

researched upon a lot of testing was being done in uh in the in the united stat States so I think it's the either

it's University of Buffalo yeah Fe there is a lab in Buffalo in USA where a lot of the research and

development part of the LCA thees mark one uh or the LC thees program as a whole has happened this was before the

uh 1998 uh nuclear test once the 1998 or 1999 uh nuclear test happened a lot of

uh restrictions were put or sanctions were put in on India and after that uh after that those sanctions our

scientists were asked to leave the leave the United States immediately and since then a lot of lot of project progress

that were being made on the LCA program went into V and that included the uh that included the engine part so after

that Eng resarch and eventually we did make some engines but it had many issues and

because of that uh did that delays had happened but we will come to see that what our country has achieved in the uh

in in the Cav Engine with the amount of funds that have been given uh the ROI has been

excellent uh people won't believe it but believe me if you complete if you compare the ROI that is return on

investment the amount of investment that India has done and the amount of investment the Western countries or even

China has done for that matter uh who say India has done a fabulous job getting directly onto a fourth four or

4.5 generation engine now enough of uh talking let's get get into the meat of the uh

discussion here so uh we will be comparing the Cav's uh thrust with the global uh Global competitors here so we

have the uh g404 that is the prime currently the primary engine for uh for the LCA tases both Mark 1 and Mark 1 a

the rd33 the Ws 13 and the m88 engine and the g414 is the uh engine for amca ws13 is for the Chinese one and ej200 is

for uh for the Euro Fighter typhoon so if you want to know which engine is using uh is on which aircraft I will uh

I will uh clear that to you so the ej200 is in the Euro Fighter typhoon g414 I I think the fa18 Super Hornet m88

is on the raal that's why I have uh there is a reason I have marked it in Green in the table and rd33 is on

the uh on the MiG 29 and the g44 as I said is on the LCS ws13 I think is on the j20 and the C as such is the subject

of our discussion so uh when we pl a scatter plot where on the x-axis we compared the dry thrust so dry thrust is

basically the uh the amount of force that the engine is producing without without the use of an After Burner so if

you compare it with compare the Cav with uh other engines one second I will U get my pointer

yeah so the amount of thrust the dry thrust the Cav is generating is is in the same almost in the same category of

the rd33 and g404 and the m88 so it it is currently producing uh around 50 k uh 50 Kon anything between 48.5 to 50 Kon

and when we see that the m88 of the raal is in its dry configuration is 50 kilon so so is the MC 29's engine that is the

rd33 and so and almost same for the g404 existing engine of the Tes and WS 13 now I will say that take the Chinese

numbers with a pinch of salt but anyways these are the uh these are the the Chinese numbers are from many Chinese

sources so they have a habit of lying to so I will say that take it with a pinch of salt but in any case uh uh the car in

drive format is a very good engine in my opinion and it is comparable to any uh any contemporary fight uh fighter jets

engine in in the medium category so if we uh if we compare if we extend the scope

of the graph to the weight so this is where the Cav's problem starts it's a heavy engine so because of the heavy

engine it it has a lot uh it it faces the major challenges as of now so so if the if you see this weight parameter so

each color represents uh a kind of the amount the total weight of the engine so I think the uh yeah the dve weight that

is without the after burners uh so if you compare uh the color wise so green or bluish is a lighter engine and the uh

in if the if this is system if the bubble is in red color then it's a relatively heavier engine so if you see

that the car isn't particularly very uh yes yes User x101 it's 1100 kg no it's not 1100 kg I will come to that it's

1180 uh so uh I will come to that user yeah uh by the way user thank you for joining in uh please

subscribe uh so yes the C engine uh is a heavier one and it this is where the problem one of the issues lies so if we

come to the weight comparison if we take uh take the 1100 kg as the Baseline so it is not as if the car engine is

extremely heavy there are many engines that are basically of the same similar category the Chinese are 1135 the g414

is 1,110 and the the C engine it's 1,18 so even if we take uh 1,100 as the

Baseline we are 80 kilos above from getting into the Contemporary uh uh or the peer uh jet engines so what is the

issue so being a heavier engine it cost the Cav a lot of lot on the thrust to uh weight ratio so it's thrust to weight

ratio is quite compromised because of the uh because of the uh High relatively higher weight again I won't

say this is a very the the margin is too high but uh there has been a lot of weight reduction exercises already on

the engine weight come weight reducing exercises the amount of technological

Prov that you need it becomes uh it becomes very challenging so that means

let's say 100 Kil weight reduce that will take almost the same amount of effort that has gone

into creating the entire engine all together that may be a but that is the issue with Material

Science as such and electronics as well system it becomes more and more challenging to reduce the weight and uh

size so as you can see the thrust to weight ratio here for the C engine suffers now specific fuel comparison so

I will say that specific fuel comparison wise the Cav is equivalent to the m88 engine so uh if you see all through

these all through these uh graphs and charts you will realize one thing that uh uh the biggest advantage of the Rafal

engine is or the the the European engines in general is that they are very light so one thing that they have sorted

out very well is their Metallurgy uh they they have they have figured out their Material Science part very well

and that has helped them to achieve this kind of uh very low weight and that helps them to uh to actually improve

their thrust to weight ratio of the engine but uh you again you can see here the the dry thrust and all that thing

buys the calary is very much close to the uh close to m88 but in the to Total thrust case that is when the Cav gets uh

gets to its After Burner part successfully it will create more thrust than the uh m88 so that is one thing uh

I will again that will uh that will raise a question that I will I will share with you guys uh in the coming

Decks that why if we say that the C engines if C engine becomes successful it it becomes almost equivalent or in

some cases better than the Rafal engine so what makes us think that the the French will uh do a transfer transfer of

technology to the to or to Dro or to us Ork so that's a question that needs to be uh to be given a thought by the uh by

the people who are in charge of this thing actually transfer of Technology despite

fact sorry market if I have to be a bit

bit light with the language now we will jump into the technical part so you have to bear with

me we will discuss what have been the challenges challenges with the c engine as such and and we will get into the

hardcore mechanical engineering and Material Science part of this uh of this engine and we will discuss in very uh

in-depth analysis so if you you see that uh we have I have this is basically the cutout of the C engine and uh these

These are if you if you understand the parts this is the fan the high pressure compressor combustion chamber the low

pressure turbine and then the then comes the After Burner so uh uh I went through a uh a slide deck shared in some uh in

some conference by uh some GT official so there they shared the part wise issues that they have been facing so the

flutter for the uh for the fan and the high compressure uh high pressure compressor that is the cold majorly the

cold section of the engine they are facing flutter and high cycle fatigue and when it comes to the hot

section these uh these issues are mostly related to uh or somewhere directly or directly uh related to uh to the high

temperatures and pressures that that comes up in the combustion chamber and the uh uh and the and the low pressure

turbine and subsequently in the After Burner part as well uh UD G does the current cover uses I think so I think

the newer one uses I will come into it ual G it's there is a section in this and we will get into the hardcore

details of uh of single Crystal blade don't worry I have covered it here uh so so this is the if you see this is the uh

list of issues that that are currently existing in the calary OR currently or I would say this this deck is from 2022 so

in the 2022 part uh in 2022 version of the calary these were the major uh issues so if you ask me uh according to

me my analysis is that the that uh when the uh engine is moving ahead in into fly uh uh flight test bed in Russia I

think they have figured figured out a lot of issues especially in the cold section they they may have figured out

the flutter and high cycle fatigue in the cold section which I will explain what are these issues and how do they

look uh and uh anyways let's move ahead so understanding High cycle fatigue so if you see this diagram uh this is

basically stress strain curve for a ductile material or let's say a metal so if you if I have to explain you this

please stick with me this is going to take some amount of efforts to understand but

for for example you take a uh let's say cycle spoke C

am after number of times cyle spoke so when you see that uh when you

see see this turbine blade here I have the turbine plate CA analysis so when you see deformation so what are the

forces on the primary forces if you see uh primary forces on a turbine blade so it is rotating at a very high speed and

for PR so you will see that there is a lot of scope for deformation uh here on the

upper part of the blade so that is the problem that uh that was causing uh the uh that is causing U failure in the uh

engine blades in the earlier Cav engine that there were deformations happening due to high cycle fatigue and

issues next is the flutter issue that is when see that is when the aerodynamic force uh aerodynamic force that is the

uh force of the air flowing and the elasticity of the I don't want to go into extreme

detail but I giving you an IDE

blades and light up pressure loss buckling after these are primarily because of the high heat so that's a

that's a kind of material science issue now uh coming to the single Crystal blades uh uh yeah so coming to the

single Crystal blades so we need to understand what is a single Crystal blade of so if you see here this is a

micro structure of titanium or any metal you take uh uh if if any metal you take there and look it look it in the

microscope uh then you will see that uh see that uh there are these little ter terrains or grains like structure with

the black color boundary to it this is these are called the uh crystals so these crystals are basically contain

atoms of the particular uh particular metal and what these actually mean is that the atoms in this case are aligned

in different ways I'm oversimplifying but but this is the fundamental part is that the atoms here in the poly Crystal

material are they are aligned in a in different directions and when these uh these grains actually interact with each

other the boundaries are formed so single Crystal blade boundaries now why are these

boundaries bad so your whenever you see that a failure happens a crack happens in a uh in a in a metal uh piece or

something the uh these these cracks actually initiate from these grain boundaries so these grain B

boundaries if these grain boundaries are removed uh this will improve the uh strength of the of the uh object by many

times uh both the strength in general or and the heat resisting capacity of the turbine blade so this brings us to the

uh diagram here so this is a poly Crystal that is multicrystal uh multi Crystal uh turbine

blade which have which is not a not a single Crystal this is columnar Crystal that is these are uh blades where the

crystal have don't uh the only they are in in the vertical Direction boundary grains and the single Crystal blade have

Have No Boundaries uh sorry no grain boundaries so this is how a single Crystal blade looks the right one here

is the single Crystal blade this is this is the uh columnar Crystal blade and this is the multi poly Crystal uh

turbine blade so we are looking to in get success in this single Crystal blade for fighter jets in this case so how is

this single Crystal turbine blades created so this single Crystal turbine blade is a is a magic of cooling uh we

have to cool the molten metal in a certain way to get this uh uh get this particular

uh structure poly crystalline structure so before that grain

boundaries so let let's move on to the metal solidification process so let's say outer

surface English thank you uh mold wall yeah

so liquid let's say m environment provide k then uh these D

these dendrites are formed uh these and these dendroides slowly move ahead towards the center of the uh center of

the whatever jar you have taken or The Crucible you have taken for solidification and these greins are

formed so this is the uh this is the uh uh the dendrite formation of in the in case of solidification of metal so in

case of in case of these single Crystal blade giving uh cold temperature from all sides but what I am telling is that

lower upper part solidification

uh uh yeah I will come to this the company's part no issues K so yeah coming to the issue that uh coming to

the part single Crystal blade so this is a Bridgman

F let's let's let's okay yeah so Bridge turbine blades

coing through water or whatever you have so and to to avoid to avoid multigrain structure filter

typ helal helal 3D sor this filters out filter out this

multiple grain formation and it allows only single Crystal to uh to propagate upwards towards the hot chamber

so single Crystal turbine blade is process cooling process uni unidirectional cooling so

Crystal and then it becomes then the entire mold is solidified into uh into a single Crystal blade

now this is a deck that I don't know where where did I actually get it I think uh I think strategic Frontier

maybe so this is from a 2022 uh 2022 uh deck that GT uh guys did so they

have they have pointed out what are the materials that they have to indigenize so if you see that the red mark they

have marked this in red dots the material that have to be indigenized you will figure out that most of these

things are related to Titanium so the good thing about the titanium we have a good news which which I will be

discussing in the next uh in the next slides so titanium issue titanium thing has been a challenge for us because uh

because in general titanium across uh Globe has been supplied primarily supplied by Russia and some handful of

certain countries I think even China is also in the is a major player in the supply chain so that is one thing so um

the good news is that PTC Industries has opened a furnance so uh how many furnance I don't know but the investment

says that it is uh the there are more than one uh furnances that has been opened for uh making these titanium

ingots uh so these titanium ingots are a very key issue in the engine and in the fighter jet development as well so you

need titanium Alloys in the engine and you need the titanium Alloys in the aircraft body as

well because it's it's strong it is light and the it is it is now has become the standard go to go to base material

for high Hightech uh military grade uh equipments now comes the uh funding part so the

these are some uh funding that I have understood that the Americans have actually pushed in more than a billion

dollar uh on their sing on single engine I'm single engine means on each of the engine development program so they have

they don't have just one engine program that's running and

development or I will come to the joke that that has been created out of cavari but if you see that uh this is a $1

billion Mark a$1 billion Mark so for say for engine development program so they have developed for jet engines Americans

have developed jet engines for uh okay okay so so somat da uh I I understood Japan is also yeah yeah yeah

uh thank you thank you thank you uh I I will come to the questions I will come to the questions once I am I am done

with the presentation uh yes so coming to the CI thing so the joke of the calary engine is that we have been able

to create of engine that's providing us with a with almost uh 7071

Kon Kon of thrust uh all with some struggles that that is very much close to uh maybe not close to what what was

needed for the LCA AES but it's it's close to many many fourth generation fet engines

uh we have compared with some of them in the 70 to 75 category the the one of them being the rd33 so the rd33 on the

mc29 uh is one engine that I think the calary spec wise comes close to but 38 years and only

2,100 and here people say Dr like are you guys serious are you guys

serious compare but they don't compare compare the funding that these platform or their

engines have got what we have achieved in a very limited constrainted budget uh is is unparalleled on and by V I mean

the drdu of course there are inefficiencies but this is unparallel the ROI is huge it can't be

compared so we should not be same again I'm coming to the same point 2100 cres in 30 years CAG writes an entire report

I will request the CAG to compare how much money has been spent on the development of each of the jet engines

in the US in the in in Europe and in France and in uh Germany and how much is being spent by the

Chinese now another issue is the uh testing infrastructure so this is the FTB the

Russian FTB platform so there was this audio that I think Alpha shared on his Twitter that when some n or some I don't

know who exactly but some n only asked why do we need flying test ped and then and the DG Aerospace then has to give a

lambach lecture by is which eventually summed up that there are there are geopolitical and strategic imp

publications of these uh testing uh facilities and test bits which is now openly visible now the this question was

asked many years ago and now we are seeing we are seeing the the price and

these and we should ask some simple question is Russia priority the French the Russians know if

the cavari is able to perform is able to come to life and become a commercialized project then

the C will if the C is succeeded we need to understand C engine successful development

Bal by the opportunities are immense once you have a functioning fighter jet engine so I I want to ask the people

ance why do they think tting they will be very glad to help us

of course they will take money but we need to understand they will deliberately want to delay the

process issue we should be having a flying test bid I

think I think we should focus on creating uh buying a bunch of uh buying bunch of passenger airliners

with four engines and convert them into ftvs I think that that is the most ssta option that we can take other than that

I don't I don't have any idea of how how are we going to uh do this uh and next is that question needs to be

asked of 70 to 75 K produce 70 K

produce or I think Aerospace 29 k After Burner eventually full full After Burner

I think it will be able to produce 80 kons easily uh because I'm now much more hopeful about the CI engine than anybody

else in anybody else because I I have some idea of the technological issues that the drdo is facing and how they are

coming up with this and I must say Dro is doing doing a brilliant job and nobody body will be able to uh able to

comprehend of aieve in the amount of money that they have been given it's a Herculean

task so coming to the existing testing facility we have this GT 130 K jet engine facility that has come up in near

to bangaluru it's a 60 acre electrical power 85 megawatt cooling water is 65 lakh L an hour and these are some major

uh a major uh this is a major facility I think some of the uh gaps the major testing gaps that I will discuss in next

slide have been addressed addressed in this facility and uh and the thing is thats live live full engine testing

flying test B ISS but I hopec some sort of environmental testing

facilities facility research and development lab existing capabilities of that testing capabilities that we

have but is that facili component

level scale mod fac component test so that is one major issue and then environmental Test

Facilities see environmental testing facility is uh is one area where uh where there is a lot of scope for any

businessman looking to invest and money because environment test environment Test Facilities

some be it in case of jet engines be it in case of Tanks apcs Radars Etc guns environmental testing facilities are a

must have for any plat military hardware platform development next is this there have been

some progress this is one uh one I got from Twitter somebody shared that dmrl designed and midani manufactured blades

used for refurbishing Jaguars engine so there so if we speak about two major players in the market who are who are

currently into uh manufacturing titanium uh or titanium uh products finished products not extracting on the or part

and refining but finished products that is midani and I think even bhat force does it to some extent I'm not clear uh

but in any case midani is one such major player so uh this is one news that I got that Dro did develop single Crystal

engine blade uh uh single Crystal engine blade that that were for helicop M for helicopters and uh and I think they will

be able to figure out something for the jet engines as well I hope so it's before 20 it's before 2030 uh the I all

these development gives me some sort of Hope but it also has a baggage of concerns for me and most of the concerns

comes from the come from the budgeting part the budgets are too low we we are not serious about this uh

B we don't look so serious now next point is the private sector jet

engine why is the private sector are not developing a jet engine so look uh I have shared I shared a lot of this

design process with you how much trial and error and time and time and money goes into it do give it a thought that

are the Indian companies uh companies willing to invest this much into uh uh developing uh developing a full grown

fighter jet engine I think not we will have smaller scale uh turbine turbine engines but I think a full scale jet

engine is uh from a private player it won't happen anytime soon because Normal games B market we don't

have a proper proper Indian uh Indian firm which is producing uh PC games on a on a global level and there are many

such things which have huge Market in India and still they still our companies don't develop things of their own and

eventually end up buying from China and sell selling here be it phones be it TVs etc etc so uh Indian Firs suffer from a

lack of R&D they think research and development are a waste of money but the thing is that their peers in uh peers in

the uh in the Western and the Chinese uh uh Chinese region are where they are today because of their huge investment

into research and development engine Chinese also a lot of [Music]

time they have been very performing very poorly till 2016

17 PA up 16 17 we are very late even the sixth generation fighter that they have

putting up now I don't think they have they the engines are as efficient as required for a sixth generation engine

and next is that we need uh uh we are uh from the from the uh presentation you might be aware that uh that the Cav

engine needs to be Diversified into other fields where gas turbine engines are are usually deployed be it in mostly

in the power sector we also can and uh spin spin off it in uh spin it off in the uh Marine engines and maybe uh other

applications wherever uh engines are gas turbine engines are can be deployed next point is that what about

JVS see JV with with Rolls-Royce G or saffran comment but we should be uh we should

make sure if we are getting into JV we should have the complete intellectual property control of whatever techn

transfer of Technology you are asking for and if it cost a hell of a money uh maybe the total amount may be equivalent

to the mrfa deal or even to the entire cost of the LCA program but make sure if you are taking transfer of Technology of

the uh of the core section it should be full and Fin no no strings attached uh

nothing no if and buts from the selling company and I think if the complete transfer of Technology happens uh it

should government should uh publish what are the what are the caveats but should not disclose what is the amount that is

if they are able to secure complete intellectual property next slide see this is my uh this is my

uh thought on the Cav's scalability U these are my thought cavar scalability is a huge competitor to Global players

uh somat this might answer to your this might be answer to your question calary scalability is a huge competitor to

Global players why will anybody give you transfer of technology to create their own competitor even if it does are there

any strings attached regarding India's sovereignty or Market access for Cav related products in future that needs to

be answered by whoever is concerned who am I but I am no one but people should know that when the

Strategic system deals regarding strategic systems happen it should not come at a cost of

our sovereignity and if it it is cost costing us our sovereignity it is better better but when it comes to investing

into our own indigen development the time we are like

nobody's now that is that is it from my uh for my presentation I hope you guys liked it and I will be up for questions

you guys can shoot your questions I will go I will start from the uh comment section

uh so I think we can make 100 K class engine but uh first we should be focusing more on the

90 80 or 80 or k class of engine because as I say as I said that once uh once you have the core sorted it's a scalable

product it's uh the once the hot section is sorted the product can be uh the product growth is exponential and

hundreds of uh spin-offs that can take place uh uh so yes one and also 130 K uh uh uh testing facility has been set up

by the drdo so it seems that they are confident uh yes if only we

have see the light sorted if only could have yeah yes K I think the high

altitude testing and the flying test bit are two most needed uh testing facilities I think if we uh even if the

flying test bed is uh prior prioritized later on uh I think we should primarily start with the uh high altitude testing

facilities first we should get that first is there a problem with C Sing core single Crystal blades uh see that

is I I don't have any information if the new engine that they are sending is with the cavi single Crystal blade uh I think

there shouldn't be any problem I hopefully uh because uh if you see if you understand that uh in the last test

in 2022 it was able to generate 48.5 to 50 Kon of thrust uh so that means the blades were doing pretty well and uh in

that case we can assume or we can in infer that uh if they have used uh used uh the single Crystal blades in the low

pressure turbine section for testing during that time it was it was working per perfectly well but again this is an

inference uh cmc's I'm not so sure if they have gone for it till now but uh a single Crystal blade maybe cmc's may

also be there I did see some uh some uh pictures of cmc's that were shared in some of the Aero indas and defense Expo

by Dr and GT on j20 can India MCA con I think USA will future said to I I will make S I will make a different

presentation for j20 and j36 and regarding amca again this takes a lot of lot of producing this deck or

presentation make a lot of effort uh I think but amca is isn't going to be a generation fighter it's going to be 5.5

generation fighter because the the core or the fundamental part of a sixth generation fighter is not just the shape

and the plantform it's all the also the avionics uh so if uh the avionics part I think if we are able to integrate well

into the amca it can be given given a uh uh capab 5.5 generation capability other than that the

thanks by welcome welcome uh please subscribe share my share thing about my channel uh okay uh I think yes so j20

j36 are a threat but even if we are able to go well with the uh with our existing su3 mki upgrade programs LCA Mark I I

think it's uh it's up for uh first flight this year and we are able to produce the uh the amca Mark 1 by 2032

or 35 then we we can be we don't need to have to worry that j36 or j20 are there we but we first need a

decent decent amount of fighter in the Indigenous fighter in the 4 to 4.5 4.5 and 5 fifth generation uh category again

the the again my thought thinking is that uh as we go ahead in time uh the technologies that will come up in in

this platform it will be better uh it will be far better in terms of uh preserving sovereignity that if these

Technologies are uh generated uh uh if these Technologies are generated inhouse majorly generated

inhouse with some foreign help uh but uh I think uh the uh the intellectual property must reside with India

that is bat s welcome s any more questions guys

[Music] okay I think uh uh that's at least C yes uh K I think this is a great thing that

the UK will get a dry car engine and I think it's a it's a good size UAV and if we are able to uh get uh get a decent

size UAV with some air to a capability uh what needs to be done to reduce

weight in our engine it's purely material sence sir it's purely Material Science we need to put more money in our

metery people don't have any idea the amount of Material Science engineer that leaves this country for pursuing uh for

pursuing their highest studies in Germany and us uh don't you think us is a threat to

India I don't think threat as per say I won't pass a sweeping statement but yes there is there are two parts in

USA that is one is very very Pro India one is very uh Not So Pro India because they The Not So Pro India part thinks

India as a binary or not in a binary but they see world as a binary that is if uh if somebody is friend with friend with

Russia then that particular country is against America they they think too much in Briner that is causing the general uh

General geopolitical issues that that are coming uh forward with uh with the within the relationship of uh USA and

America I will I will also create uh some geopolitical decks next week next week will be focused on geopolitics and

uh and we will let uh explore more about the geopolitical scenario overall Swift and gatak should be

produced even uh a good amount will be 100 150 decent uks will be will be at will be a decent number yeah

any more questions guys I think so this as I said I can't say with with the complete uh uh

complete Authority that if it's in there or not but considering that in the in the prior test the engine was able to

overd deliver on The Benchmark uh that uh that alone proves that there uh uh that the engine was able to uh able to

sustain uh increased temperatures in the low pressure turbine part and that gives me a hint that the new uh single Crystal

blades might have been there because a drd already has uh already has delivered single Crystal turbine blade for

helicopter uh hel to be used in helicopters as I to be used in helicopters to H this is the uh this is

the single Crystal blade that drdo has developed so I think that they have Incorporated single Crystal blade but

I'm I can't say with the perfect show or complete shity any more question guys uh I see Swift

and should be G should India not have g s g414 to backup we have one 30 K test facility

coming up so this this particular I will come I will show you that here I will come to that slide so this particular

engine that the gentleman here was discussing was was of a potential uh AMC J engine of the 110 category uh class so

yes uh we are looking for alternative to G g414 might might not be that government has not funded any such

product yet but I think drdo is uh is focusing on research of this based on its internal funds but again any all any

and all engine programs regarding fighter jet engines must be now taken into motion mode and these these

Laboratories that are handling these projects must be uh you know bring into the Ambit of the prime minister's office

for Rapid uh rapid results as the Baba Atomic research and the ISRO Israel like organizations are in under the purview

of prime minister organiz uh prime minister's office anything on our am

any any video or live I will do it uh thank you for the for for the idea I will make a a separate live for it I

will definitely make uh but as of now I I will keep you updated on my Twitter so please please follow me on Twitter at

least 6 to8 billion must be yes yes subaman G I think $6 to8 billion doar is enough even it's a why we we are funding

uh funding your MSP of 12 2 lakh billion uh 2 lakh CR is approximately

uh and $24 billion in MSP uh so6 to8 billion is onetime investment is enough for next 10 years for engine development

uh it will bear a tremendous results I am 100% sure about it it will bear tremendous

results fund the Z engine $ 6 to8 billion uh thank you uh uh 6 to8 billion is more

than enough for a decade of research and development part uh and we will see results pretty fast if if that kind of

funding is given but again I'm sure the the baboos won't let it happen but they will have 12 billion to buy and imported

uh something something so that's a that there is also a mindset issue a huge mindset

issue any more question guys uh anything I can address or help you with uh I

think the son G to your last question pre some of the previous question I missed yes Manor parar was indeed the

best uh uh defense minister for indigenous programs period he was the best

indeed UHC regarding again regarding the FCS and

the Gap Tempest six generation fighter J uh I am again of the I have two two points to make first is that how much

intellectual property we are owning second is the how much of the manufacturing or the supply chain uh we

uh we have a part in so and when we get into a war we have to run to the British or to

some other European country the LCA the LCA Mark 2 Mark 1 a the amca will give you complete control

over the source code you don't need anybody's permission uh to implement new weapons so in if if you think about the

LCA program I think the LCA program uh uh uh LCA program or the LCA jet is the only fighter jet possibly in the world

which can incorporate Indian weapons American weapons Russian weapons Israeli weapons French weapons and the UK

weapons so yes uh I think LCA has is a unique platform on its own sixth generation fighter will require

much more power bigger power plant that's why I said the amca won't be five entirely sixth generation fighter jet

but if the AV the avionics part can be uh addressed and it can become a 5.5 plus generation

fter and as I said the if the engine is sorted if the Cav is sorted and the hot section we are able to figure out now

it's a very scalable product it won't take much time to make spin-offs for even for uh passenger jets for gas

Marine Engines it's a huge the C engine it's a uh is a huge project of strategic interest and that

is why there are many interests that don't want the Cav to succeed that is also one thing so

you must understand there are many uh many vested interest that are against the cavar and they will keep on bad

mouthing the calary but we must ask one question do compare how much amount has been uh invested into the development of

cavari in last 10 years and how much has been has the Chinese spent on developing their engines in the last 10 years and

what has been the output fundamentally the ROI for Cav is huge nobody understands that

point so yes guys that I think that that will be it for today's live I I I really appreciate that you guys joined in

um important it takes a lot of effort to uh to make this uh deck for you guys and you might have noticed that this is

possibly one of the very few uh uh uh are there any titanium in engine increasing the the

current as rection is causing the most trouble suban G I think the the After Burner

part is the most troubling issue right now uh I think the titanium part is not the uh problem that

is that is causing the issue but there are there may be as I said in the in the problem part I will share it

again uh so you see so you see

this the hot section part is the most troubling part and out of that the After Burner part is the most troubling part

so the the the After Burner is also called the reheat system uh and the temperature here goes even Beyond to the

what is in the in the in the low pressure turbine part so there comes the issue that uh once the After Burner is

implemented to augment uh augment the lack of metallurgical skills we have to increase uh

increase the weight by adding more amount of material to to avoid any kind of failure uh in the After Burner that

is causing primary primarily causing the increase in weight also the the weight currently is also a

matter of Simply Metallurgy since titanium is not the fundamental uh issue the Alloys are so the Alloys are

basically tighten tianium plus something some other metal plus some other metal multiple Metals creating a creating an

ideal mix of weight and strength that that is a very trial and error and trial and error kind of a job and takes a lot

of research and development so you have to be particularly very much uh very much on the uh perfect composition of

alloy that will give you uh A reduced weight and uh uh and the strength that you

require uh does the C derivative also way I don't think so it will be lighter uh I think uh the new variants that that

are going into Russia may be a bit lighter but again I say that there is 30 to 35 uh Kil sorry 30 to 35 kg uh 1180

kgs and the ws13 is around 1135 so uh so if that's only difference of 45 kilos Visa V the Chinese engine and Visa

the the g44 100 kilos and g414 it is around uh around 70 OD kilos so we are close and the thing is with

this kind of development is that as we get closer to our uh closer to our uh Benchmark it becomes even more difficult

to achieve that's that's a general life Principle as well uh so uh uh yes subaman G uh we have to get

the correct composition of the alloy that is the issue titanium is not directly used the Alloys are important

part uh so that is uh and the research on Allo has to be done and the compositions had to be figured out that

is where AI can be used actually uh that is one place where AIS can be used to come out

with a with set of composition that uh that satisfied our satisfies our boundary conditions uh yes so

a I think yes even I am waiting G for the AO India lot of lot of information will come from there as well I hope uh

you you guys liked it that will be it from my end uh two more minutes any more questions and then we I will be done for

this life yes yes mahes g i I will humbly request you to see my yesterday's live I

I I did a comparison on uh with with the Archer and uh Archer tb2 and the shaer Drone and the ch3 Chinese drone I will

request Mah G you get go and have a look on my channel uh on on the live section part you will see yesterday's video uh

again uh again M I will request you to subscribe if not you if you have not subscribed uh guys any more questions

okay okay guys I think that will be it from my end I hope you guys liked it it takes a lot of effort to create

this uh this this live uh presentations for you uh Mah G thank you yeah please go

through my channel there you will find a lot of unique videos I make a lot of things U needless to say very detailed

analysis every in everything uh yes subaman G thank welcome you're welcome uh yes uh I think uh I I humbly uh

appreciate appreciate you guys for taking out your your time for today's presentation and giving a chance to a

new channel like me I hope I I have been able to deliver uh good value to your time so that's that will be it from my

end guys thank you very much and I will be out in 5

4 3 2 1 thank you guys thank you thank you

thanks a lot bye-bye J Hind
