Yes, it used to copy Russian turbojet engines, but then started to develop it's own turbojet engines. All of the turbofan engines that have been developed (WS-9, WS-10A, WS-11) are all based on other turbofan engines, but not clones. Again, I have to reiterate that these engines are not copies, but rather based on other engines.

Could we even once discuss india related matter wihtout making comments that all indian efforts are fruitless and the usual counterreaction to those...what good have china produced...??

To those chinese ones who seem to have such a strong feelings towards anything indian, could just ignore this and other similar threads? We don't allow india-china comparison threads anymore, so why does threads simply concerning india have to be dragged to those unfruitless depates?

This particular thread is in the world defence arena so let it be solely devoded to inida, OK?

why build your own engine from scratch when theres clearly more potential and time to be saved from basing it off of another engine? russias first jet engine was the rolls royce nene. but after 40 years of further devloping the engine, they have the al-31.

the kaveri is good engien ofr a light aircraft like lca, but perhaps a more powerful one would be needed for mrca. solution? build an engine off of the ge-404. thats what the swedes did with the gripen.

It's still better to develop your own engine. Especially since India is planning to use indigenous engine for MCA. Every country that strives to be self-dependent has to get through the major hurdle of turbofan engine development. It takes a long time, but the technological breakthroughs are probably worth it.

Personally I think the MCA and 5 gen concept Mapo MiG is in talks with India will have shared tech. They could use the same engine ie the one developed for MiG-1.42. But from what I know the engine for a 5 gen is underpowered. Russia and India could co-develop a new engine for more thrust. I think InAF is in talks with Mapo MiG to develop a single engine 5gen combat aircraft. Which means a new powerfull engine will be needed. The Pak-Fa has 2 engines. MCA could use the same engines on the MiG concept. A 5th generation engine is in the concept stage in GTRE but they have their hands full with the Kaveri. They want to develop a TVC Kaveri in the near future. Russia could take the load off.
HAL is also busy with a stretched LCA concept and studies have been done for it. They, from what i've heard from Harry have even thought about canards, and tail less LCA for the future. Theres a lot of effort from HAL to reduce the RCS so the LCA can play an important role in the future.

so your saying the new indian fihters should use al-41? good choice.
the al-41 is a great engine, although it lacks supercruise. which probably is why russia has been eager to get freign investros in the project, to futher devleop the engine.

Al-41? Isn't that the article 1.42 engine? Then it should have supercruise. But the engine on 1.42 is underpowered. I believe a new engine should be developed. Russian's have good experience in engines. But when it comes to quality. They lack it. Remember the difference from the first F-15 and Su-27. ugh...

lol, the Russian engines are definitely not high on quality. I remember reading that none of the AL-31F engines that China got ever reached their specs in terms of service time.

Btw, I read somewhere that AL-31FP would have problems with engine blades after less than 100 hours of service. I guess since India is producing AL-31FP by itself, the quality of the engine should be higher than the Russian ones?

ding ding ding ding

WS-10A just got certified.

Reason why Russians probabily went for twin engines. But I think the liecence production is only assembling. Most of the engine components probabiliy come from Russia.
