We need a good engine at any cost. A 75 Kn Dry and /125 KN + afterburner is the need of hour.
It's impossible, they already choose a smaller very efficient And maintainance friendly engine f414.
They cannot use a f110 class like 75kn or even more kn engine... If they would have felt to use that class engine they would have preferred Ge f110 which has 73 to 84kn thrust engine variants... But then it's a very heavy engine almost 1.8 tons which even if we would have made indigenously of same class would have not weighed less than that... It's maintenance is more, very less service life compared to f414...
F414 also has 65kn dry variants.

No, they don't hate India.
The issue is that India doesn't pay the price as much as Chinese did.
Even before Chinese became West's ally, over 70 Chinese divisions were deployed on the Sino-Soviet border.
After Chinese signed the deal with US, the understanding was as soon as the WW3 starts, no matter who started, these 72 Chinese divisions would match north immediately to hold 40 soivet divisions so they couldn't move to Europe. As the consequence, Chinese were willing to bear over 2000 Soviet nukes attack.
That was the price Chinese was willing to pay for these techs.
So in other words while the CCP rails about the century of humiliation blaming the west for it , the CCP has no qualms being tbe west's bitch when it suits it , willing to sacrifice the lives of its Han slaves.

Man , the CCP & the Han slaves they lord it over certainly deserve each other .

Kiddo, just go back to play your toy. You won't understand these before you grow up.

Uncle is the going rate for wumaos still 50 cents like it has been for the past 20 years or has the communist socialist leaning CCP hiked those rates for the poor exploited proletariat which is why the CCP was formed in the first place ?

No ?

You can see why the Han is still a slave to the CCP. , 100 years of humiliation notwithstanding.

Did u see recently the evergrande biggest real estate companies of china is being sold because it cannot pay it's debt I also read stories of customers who took loans for houses but did not got on time and they defaulted there loans.when bank went to sease there house, the house didn't exist because the floor was constructed yet...
Wu mao 50- cent bot. You're country's image is all created by funding media you're countries budget has 5 billion for this and also by isolating them of world on internet.. it doesn't matter how big better railways u have they are all loss making and meant to just show big number in GDP growth that's it. The housing real estate is no different from this..

Do you know that we have chosen GE 414 for AMCA and we have a plan to use Proposed 75 KN dry /125 KN after burner in AMCA 2? That engine will make AMCA fastest 5th generation plane.

Now look at the Dimension of Both the engines.

GE f 110 dimension from en.wikipedia.org

Type: Afterburning turbofan · Length: 181.9 in (462 cm) for -100, 232 in (589 cm) for -400 · Diameter: 35.66 in (90.6 cm) inlet, 46.5 in (118.1 cm) overall · Dry ...

Specifications[edit]
F414-GE-400[edit]

Data from GE Aviation,[33] Deagal.com,[34] and MTU Aero Engines[35]

General characteristics
  • Type: Afterburning turbofan
  • Length: 154 in (391 cm)
  • Diameter: 35 in (89 cm)
  • Dry weight: 2,445 lb (1,110 kg) max weight

Now notice the difference in dimension. this is the reason why they can not be use interchangeably. When we talk of this proposed engine, it has the ability to replace the GE 414 without any major modification in airframe. Some times GE 414 EPE is also discussed which will be of same size but will have higher power. So it will be fit to be used as replacement and not any other engine.

When we planned to used proposed new engine, defense experts said that it will reach the top speed of 2600 KMPH i.e 2.15 mach revised from 1.8 mach with GE 414. Now extending same logic, MWF may also have significantly higher performance with proposed new engine. More importantly, higher dry thrust will help batter performance in super cruise which is revised to Mach 1.6 for AMCA with New engine.

Very few amca mk1 are going to be build

Did I say anything different ??
For ur knowledge there are Varints of f414 epe & ede which can make 75kn dry and 28500pounds wet I read this on ge yt video so u can do conversion in kn (may be 115kn)
The ede has 3 times more components life d means durability (I read this on ge website article of 2001 when they were seeking funding for this development...
This epe & ede are same but ede is rated for similar power output of a f414-400 engine which is 58or 61 or some article say 65kn dry (depending on Variants) and 98kn wet.. basically it's epe but rated for low power for replacement of f414-400.

Epe has very significant changes as it's a next generation leap. The compressor was completely newly designed.. to sustain higher thrusts. It reduced 1 HP stage to 6 total hp stages.
Just like the pratt Whitney f119 with just 6 HP stages..
Retaining very high dry thrust... And MOST IMPORTANT 3-4% LESS SFC.
The epe dry thrust is around 75kn and wet 117kn.

And forget about the amca mk2 engine long time to go there Tejas mk2 will be there before 2030..
Million dollar question is is in6 Variant based on epe variants which has significant higher performance and 3-4% lower SFC..
Or they are choosing 3x more life over performance and going for derated epe variant f414-ede.

I answered you why F 110 with higher thrust can not used in AMCA/MWF and GE 414 EPE or Proposed new Kaveri (Or whatever name it may have) shall be used in AMCA and How it will enhance the Performance of the Duo. Provide the Referance of 3X life.

Well 3x life is of epe version when operated at same power outputs of f414-400.
It is derated epe with same 6HP.stages new compressor..
And go check out the first screen shot the same article has that mention. On top
it's not in screen shot ,okay
Search ge seeking funding for new epe development u will find it..

Well ede & epe have same changes or upgrades whatever it is..
Epe has 25% increase in thrust & ede has 15% increase in thrust compared to baseline f414..
Although ede has 3x more components life of hot core section..
Overhaul time for both f404& f414 baseline Variant is 4000hrs and 6k hrs life..
This ede has increased overhaul time to 6k.hrs so it will have long life like f22s & f35s engine they have somewhere between 9-10k hrs operational life..

Does anyone follow Chinese economic policy?
The reason Evergrande and other property developers got into today's trouble is: Chinese government stopped the banks providing loan to those companies with super high leverage by declaring the so called "3 red lines" policy. Until today, the government only allows loans for those unfinished projects instead of saving these developers.
In other words, the CCP is proactively burst this bubble before it grows big enough to kill everyone.
As I explained before, property market is a big problem for China. China would have a difficult period when they are fixing it.
The bad news is that China is in this period now.
The good news is that China didn't wait to the final minute.

But anyway, I think our Indian friends here don't need this kind of thinking.
Let's repeat: China is collapsing. :)

Everything except high altitude we don't even have an aircraft to do high altitude testing
Yeah I know . ISRO has a high altitude test facility for liquid rocket engines . Shouldn't be a massive effort to have one for turbofans . I mean if this facility is only there to mount engines and check their measrements then this is probably not worthy of a press release.
