LCA TEJAS MK-I & MK-IA: News and Discussion

[Blood+]

don't even have the capacity to manufacture and deliver 200 engines on time, same with France.
It would not have made much of a difference but we could've gotten at least 2 to 3 engines per year till now and upto 10 engines once the supply chain issue was solved.

Burgericans on the other hand has declared unofficial sanction as we got 0 engines in two years

Too far, my guy... too far.

Somebody please educate us on the jet engine hot core technology issue. That is the issue which is dogging the Kaveri engine. Can any of the tech obtained from GE engine collaboration useful.

The Government of India should downgrade work on Kaveri and stop listening to sweet talk of DRDO.

Fire all the people working on Kaveri engine and then start afresh.

To be fair, a new jet engine costs billions of dollars to develop - and that if you already know how to develop jet engines when you start on developing a new one. How much funding did GOI put into GTRE over the decades it was trying to develop Kaveri? I am not saying that GTRE and others involved did everything as well as could be done but I suspect that it was near impossible to develop the engine with the funding provided

Fire all of your workforce who actually know to work on jet engine and start new hmmm seems good

Funding is immaterial if project management is efficient or personnel are not working retirement on this job whether the project completed it not.

That indiscipline can only be dealt with when you start a fresh under new management
(Preferably private sector) and greater discipline. They begin where the previous team left. Ask for help from others and pay for it.

Cheers

No!!!! Keep raising bonuses to those who keep working to grt it right and give them what they have been asking all along without delay instead of being penny pinching and constantly renegotiating the terms that you has agreed to prior.

Bhai engine nahin, udee ga kaha se

We are back to lobby era..... either su mki will ordered more or new jets will come.

Must be investigated who chutiaaa banda selected GE engine. May be its a plan to end our fighter program.

This seems to be a pervasive issue, the guys who design the stuff seem to be in love with engines that come from unreliable supplier goras.

There's the GE marine gas turbine used in the warships, GE F404 used in Tejas, some Cummins engine( US ) used because Germoney was doing drama over the earlier selected MTU engine.

We used to have a reliable supplier in the past, why weren't they chosen?



Is their engine quality that bad? like the pigs made Junk Fighter 17 on the basis of the same Rooskie engine used in Mig-29

LCA when was envisaged it was envisaged with cutting edge technologies of that era in the mind: quadraplex FBW,FAEDAC based high tw ratio lighter turbofan engine, carbon composites based structure. Soviet had none or did not share them. They themselves had not perfected technologies.

Reason why India was keen on such technologies was Pak was mulling to get F16s which were cutting edge fighters of that time. India purchased almost every fighter which it thought were supposedly counter to F16 - mig 23, mig 29 and even Mirage 2000.

all had certain degree counter capability but in terms of technology none of them matched F16. Thats where LCA specifications come to mind.

How Kaveris specification were drawn- GTRE did overstep its capabilities, A engine class of F414 but smaller in dimensions which also aimed to incorporate variable cycle in it's design while on a budget which barely produced modern gasoline engine(sarcasm).

Kaveri Team has learnt lessons/learnings - important is to capitalize on them and ask them to rebuild AL31F but with better materials and use the engines for AMCA, meanwhile also researching on better AL31F. kaveri should be tested on dedicated FTB. Govt must purchase a second hand il76 and get it modified inhouse.. You cannot use an airline plane because of low wing. You need high wing aircraft.

I do not understand why GE is being questioned as an engine supplier. GE F404 was chosen by several countries to power their aircraft - India, Sweden, ROK ,Turkiye.

If you happen to be a US hater, that may make Russian engines more attractive to you. That may be your view but it was not the view of several countries that evaluated which engine to use in their aircraft.

Its not hate. But its about sticking to bird in hand rather than wishing cajoling crying for birds in burger land

No one's questioning GE's competence.
GE clearly has the superior engines, otherwise India wouldn't have chosen the GE F404s.
Remember, we chose GE despite our political history and actual fighter jet R&D history with the US, which is fraught with US playing spoil sport.


Global engine shortages whether it is because of the Ukrainian conflict or some commercial considerations of GE or Pentagon or whatever, IS HAPPENING; so, an available aero-engine is better than no engine, which is what people are speculating.

I dont know how many times i have to say this, the global engine crisis is a direct consequence of chinese hogging the supply of Russian titanium SO as to starve everyone else.

Thus the reason why India and the US have been going so hard on critical minerals together. The leadership of the two countries know what the true challenges are.

Are you sure it's that and not GE bowing to Daddy State Dept's pressure?
Which other countries, especially (((US allies))) face such delays? iirc there is a korean stealth jet in development, that also uses some GE engine, do they get delays too?

Funny that you mention S.Korea.

They quickly figured out a local assembly contract when they selected the 414 - unlike us.

You really think this would be granted to us even if it was part of contract conditions?

So i am correct, delays are only for (((non-ally))) nations like us, even if there is a titanium shortage, military engine supplies are still being prioritized for (((allies))).

Meanwhile i'm getting some conflicting info about TFX Kaan of Turki, wiki says it is supposed to use some RR engines built in turkey as a JV but GE has also delivered some engines in 2022.

Most of the Euros and their 6th gen fighters are still in planning stage so you only have the Turkish and Korean jets

Trying to ascertain now whether being just an (((ally))) like Turkey is enough or do you have to be a good (((ally))) like S.Korea who doesn't do ungli like Turkey does.

smh they should have just stuck with those shitty rooskie engines, atleast Rooskie would supply us those without any T&C, now thanks to their invasion of Ukraine even that possibility is gone.

I hope atleast we have good anti-air systems

AS far as I know. RR and Turkiye could not agree ToT so thoughts of co-operation were dropped. Turkiye is taking a step by step approach to developing an engine for KAAN: 6,000 lb thrust dry engine > 10,000 lb thrust afterburner version > 35,000 lb thrust afterburning engine. Lessons learnt from the smaller engines feed into the design of the KAAN engine. Allowance was made for the engine to fall short on design thrust but still be adequate for use in KAAN.

Turkiye has invested heavily into engine development and development equipment (wind tunnels, test chambers etc) so should be able to develop an engine for KAAN by itself. If GOI had been serious about getting Kaveri developed for use in Tejas, it would have done something similar.

If F404 supply problems delay Mk1A full rate production for a year that is doubtless a massive inconvenience to HAL and IAF but is there any reason why frames cannot be assembled and stored and engines be fitted when available?
