ADA Tejas Mark-II/Medium Weight Fighter

[eastern_bhartiya]

Let’s hope the Kaveri or some another engine is ready within next 10 years. Trump is a businessman who cares only about American interests. If US military-industrial complex sees the Tejas MK2 as a threat to F-16, they may stop supplying engines to India.

Kaveri's gonna take 7-10 years to get complete. Picking another engine rn isn't possible. Sadly enough we're stuck with Americans.

I don't see Kaveri being ready until all Mk1A's ordered have been built. Apart from the PSU-style culture and administration slowing things down, unrealistically low funding is likely to slow development down further.

M-88 produces about 75kN IIRC, whereas a much more powerful engine is required to get close to F414 thrust . Would take time and a lot of money.

EJ-200 produces 90kN. Perhaps EJ-200 is a better idea - a small decrease in thrust would match F404-IN20 output while a relatively small increase would match F414 output. IIRC when EJ-200 was selected for Eurofighter, the brief required an engine where the thrust could be augmented (a) by 20% (b) by 30%. That would bring thrust up to (a) 108kN, (b) 117kN.

One base engine could span Tejas Mk1/Mk1A, Tejas Mk2, AMCA Mk1 and AMCA Mk 2.

Dev cost: presumably derating the 90kN version to would not be expensive while augmenting thrust by 20% or 30% (with some of the design work already done) would be much, much cheaper and much, much faster than starting a new engine from scratch.

While not ideal, it may cover all the bases, so to speak. Most importantly, GOI may actually be prepared to finance the project. And Eurojet may be prepared to part with a lot of IP - at least for the detuned version.

No clue if this has been posted in some other thread . Nevertheless, here we go...

So clean frontal rcs will be in range of 0.1-0.2 m2.
Same category as latest blk3 super hornet.

Some GE F414 info provided by a poster on another forum

The F414 is the most advanced jet engine in the world to ever enter production. Letting a third world country buy an aircraft with this engine is a big threat.

The F414 has the highest pressure ratio of any afterburning turbofan in the world. It has a thrust to weight ratio higher than the engines in the F-22 and F-35. This extreme performance is still achieved despite the engine being derated well below its maximum performance. This derating gives the F414 a massive 6,000 hours between overhauls. This is longer than any other afterburning turbofan in the world. The EJ200 in the Eurofighter and F119 in the F-22 are 2,000 hours between overhauls. All of the Russian fighter engines have a time between overhauls of less than 500 hours.

Sounds like a devastating engine. While India may be allowed to use it, would the US block its supply to many potential Tejas Mk2 customers? That would favour a backup engine being acquired in case of supply problems with F414.

If you quote some random punk who starts off with racist cliches like "third world countries ," you risk getting blasted in here for no other fault than to be a vector of such offensive messages in here.

Like how selling f414 is a big threat ?
They're are not just selling infact letting us manufacture 80% of it.
Tell this thing to that boi.

The actual RCS number matters. If LCA is suppose 1 sqm, then MWF would be 0.25 sqm.
Our DoD has already claimed pocket & maintenance friendly RAS & NiRaLa, Adrishya RAM. With geometric treatment & our newly developed RAS, RAM & further R&D improvements, it can become affordable AMWF in our Socialist mixed economy compared to Capitalist free market economy, at par with AMCA & F-35, eliminating possibility of future imports of Su-75, F-35, etc.
That would be reducing RCS by not just 1/4th but 1/1000th which was done 30 years back in 1990s by USA.

The Much bigger challenge is developing RAM that lasts longer, not as fragile to high speed, not easily degradable.
The ram of f22 30 years ago sucks at these things compared to modern ram coating like on f35.
Our ram is more similar to( don't know if its as good as f35 ram) is f35 one than f22

And pretty sure rcs of mk2 being 1/4 means our modern ram played a majority role( along with smoother surface and less exposed seams) because mk2 does not stealthy geometric shape, it's shape is still simular of mk1 but frontal median spherical rcs is 1/4 of mk1.

Show me any reference to 'racism' in this from wikipedia

The term Third World arose during the Cold War to define countries that remained non-aligned with either NATO or the Warsaw Pact. The United States, Canada, Taiwan, Japan, South Korea, Western European countries and other allies represented the "First World", while the Soviet Union, China, Cuba, North Korea, Vietnam, and their allies represented the "Second World".

Where is the offence in the term 'third world country'? I confess my understanding of the term is that it is more a description of limited economic and administrative development.

Pretty sure the guy implied it with negative prejudice when he said third world.
Like how "nigger" is also just a word to describe african people, but used in racist manner.
Like how pajeet is just a name of some Punjabi guy, but used as a racist slang

Also Pretty sure you already knew all this, but still had some weird urge to do mental gymnastics

Imao Tejas mk2 is not happening in this year , may be rollout in next year

Yeah it was clear when some last retd airforce official posted that mk2 roll will happen next year Q1 and FF Q4

I always believe vayu
People can call them import shill but they are hell accurate

Of course we can fly an empty shell marking it as success but except for satisfying egos that would not achieve anything.

All fuselage are not completed yet
Later it will go to equipping stage ....leta hope for the best.....still possible in last quarter of this year

Neither were you nor was I born yesterday. This condescending attitude , left handed compliments , casual racism & so on from members of the west is something I've grown used to but not inured to in the nearly 2 decades I've been on Social Media.

That man seems to be implying that just coz we're a third world country we don't deserve those Turbo Fans coz we're a threat ? In what manner ? Coz we can't afford it ? Or does he fear we'd reverse engineer it ?

Or in all likelihood he seems to be implying we'd go to the Russians with this tech in which case he should've been clear enough in his choice of words & not come across as a twit.

Until the LCA 2/AMCA management is taken out of Babu management of HAL, there is good chance that many other deadlines will be missed. Then keep the IAF tip-top, it is essential to buy F-35. That will keep Pakistan mired in trying to equalize with India. Actually that is what India wants that they spend whatever money they have on buying inferior Chinese or Turkish stealth fighters and stay bankrupt.

Alternative is to put under PMO or privatize it and let the business remove Babudom from project management.

The Much bigger challenge is developing RAM that lasts longer, not as fragile to high speed, not easily degradable.

Only continous R&D improves things.
Now multiple nations have developed their version of the usual RAM.
But USA also developed ceramic RF blockers & Transpiration cooling for engines of F-22/35 in 1990s itself. Russia may have developed it now for AL-51 engine. EU will catch up for their GCAP, FCAS.

The ram of f22 30 years ago sucks at these things compared to modern ram coating like on f35.

Exact RAM application is secret, only shallow info available.

And pretty sure rcs of mk2 being 1/4 means our modern ram played a majority role( along with smoother surface and less exposed seams) because mk2 does not stealthy geometric shape, it's shape is still simular of mk1 but frontal median spherical rcs is 1/4 of mk1.

IDK what they didsupposed to be secret.
Stealth is collective effort of RAM, RAS, shape, EW, but the 4gen airframe itself is obsolete no matter how much it is praised & justified.
We should start AMWF immediately this year, before China, Sweden, S.Korea, Turkey, etc do it. Otherwise Su-75 tender is also coming.

I posted some info indirectly about Tejas Mk2 from a knowledgeable source. The reaction? Some strange kickback about stereotypes and racism. Too many presume to know how the opinions of others are formed when they are not in a position to know.

Where is there implication of 'negative prejudice' in using the term 'third world country'?
