We are perversely dependent on Russia for line items and strategic items. But the west also realises that we are a key player, in fact a heavyweight, when it comes to dealing with China. So I expect pragmatism from the west. They are no fools. And they also know that trying to coerce India will not have the outcomes they are looking for. India should use this opportunity of a financially weakened Russia to gobble up as much IP as it can from them. Upgrades of Russian equipment should be done in India using Indian tech as much as possible. And future Russian purchases should be reconsidered. The S400 should be the last major Russian import. XR-SAM should be the way forward. I do not think the 21 MiG 29s and 12 Su 30s are going to happen.
I am afraid it is the opposite. Originally, it requires 2 x 110kn to archive super-cruise for AMCA. Now suddenly, everyone starts talking about 125kn, it implies one possibility: Indian scientists realize that AMCA may be heavier than their initial calculation.
Because variable cycle engine means you will need to change the engine's working model between turbojet and turbofan by changing internal physical structure when flying. It can be simplified as: you will need some material with super strength to build some small doors to move in the high speedy hot air flow. Meanwhile you need to keep the weight and cost in check.
It could be that this future engine produces 110KN in Indian conditions, & 125KN in Western environment. Engine power drops in hotter climes by as much as 10% compared to cooler Europe, Russia & US where the air is denser at all altitudes, 125*.9 = 112.5. They must adopt the 125KN name for uniformity (for ease of benchmarking), clarity of purpose and also to capture the enormous leap it will be over anything within our grasp today. Said engine must generate 80-90/120-125KN in ~4m length.
Maybe we should ask to renegotiate prices for S-400 and Super Sukhoi and engine IP. Come up with some excuse about sanctions and dropping ruble values. Or whatever they came up with when they doubled the price of Vikramaditya.
Better to go for Hypersonics. S400 is already contracted, Super Sukhoi isn't that big a challenge- govt can do it inhouse if it's willing to spend money. Hypersonics can be a real gamechanger and Ruskies have quite good development- something like Brahmos
I am afraid a engine is not designed around an aircraft with engine power drops in warmer climate assumption. The engine will be rated and tested at 125KN. And AMCA has to be designed for that range and power and not 110KN.
Yes it will be. There is a reason why Koreans call their KFX 4.5th gen and not 5th gen cos it uses F414 engine with around 100KN. The turks are going with heavy engine from.the start with F16 engine rated at 130KN. I think many pointed out that 110KN engine won't be enough if AMCA want to achieve air superiority. ADA scientists have come to the same conclusion. 125KN is the right way to go about it. Better to be safe.than sorry.
125kn will be 110kn in indian condition unless plan is to prepare 125kn indian condition engine ( which is 140 kn euro engine)
You know it because ? You read some op ed or you contacted scientists ??
Common sense? And this news article from The Hindu is saying a deal is expected in 2 months for AmCA deal? And Koreans calling their fighter 4.5th gen. They are refraining from calling it 5th gen.
125KN will be an overkill for AMCA, at MTOW of 25T ,it will have T/W of exactly 1. Show me which fighter, be it a 4.5Gen or 5th Gen which had T/W= 1 at MTOW ?
There was always scope for 15pc thrust increment.
Koreans are calling kfx as 4.5 gen because it lacks iwb , lot of antenna aren't conformal , irst in place of conformal DAS , no EOTS , plus engine .
If I am right variable cycle Engines are meant for 6th generation aircrafts. We don't even know what makes a 6th generation aircraft. The British who are working on it say they are employing Big data, Artificial Intelligence for their tempest project. But still nothing is clear as of yet. Yes the variable engine is one key difference which will distinguish 6th generation jets. And what else exactly? Americans have already learnt the hard way that 5th generation jets are expensive in terms of R & D and also to maintain and their flying cost per hour. That is why they are back to inducting more F-15's in their arsenal even though they are to receive more F-35's. Once USAF knew F-22 was eating into their budget they had to stop production of F-22's.
That MTOW will increase if you have more thrust. MTOW will shift closer to 30 ton mark if you put those engines and your T/W will remain at 0.8 or so
