Comprehension fail!!!!! You still buy russian engines! Losers! SUPPA POWAAAAAA needs russian engines! 50+ yrs and still working on it! Losers! After trying to copy you still failed. Chinese Physics and Chinese engineering SUPPA FAIL! You guys just got owned on this topic. Now go shooo and find some other thread.
Come back and talk about Indian engines when you stop buying Russian engines. People with glass houses should not throw stones!
Suriya Kiran, I have no comprehension problems; it is all with you. China uses domestic engines AND buys Russian engines because domestic engine production rate is not high enough. There is no plane with no engines and thus no J-20? So what is that black twin-engined delta-canard flying in China? It's not a plane according to you, so it is a bird? Clean out the cow dung in your ears cus it's getting in your brain. Chinese jets fly with both domestic and foreign engines. Indian planes fly with only foreign engines. Otherwise, if you use your definition (no domestic engine, no plane) then India has no planes and China has a handful of J-11B and 1 J-10B. (I believe from pics that J-20 flies on WS-10X but that's not proven.)
India started engine development in 1980s and still doesn't fly any jet with it. You think a slower starting point is a merit? That just means you guys are so stupid, it took you 10 more years to even understand you need engines! The world doesn't care when you started or how long you took; it cares when you finish. WS-10A was finished around 2010, powering operational aircraft. India's is nowhere to be seen in 2012. We took a long time, and our engine flies. You have not succeeded yet and decided to just downgrade it's use so you can lower the standard.
Chinese aerospace has its flaws and weaknesses. They are working hard to correct all of them. HOWEVER, India's flaws are much much worse. You have no right to talk. Don't you feel shame berating China's engines that fly aircraft when yours is getting down-graded to drone use? And whether or not that can succeed is very much in doubt.
For you, cow-piss drinking retard, I summarize.
1. WS-10A powers operational aircraft and Kaveri does not even power a prototype on taxi runs.
2. Chinese fighters fly with both Chinese and Russian engines; India's fly with only foreign engines.
3. China buys more Russian engines because we make so many planes per year, our new engine production line cannot keep up yet.
4. India is much weaker in every respect to building fighter jets than China, especially in engines.
5. China took a long time, but India has so far failed. You have to at least succeed before complaining someone else took too long. You have no right to talk to the Chinese about engines.
6. Development time does not matter. Finishing time matters. Chinese WS-10A powers operational jets in 2010. When will an Indian engine power operational fighter jets?
Look at all this cow dung curry flying out of your mouth even though WS-10A flies flankers and Kaveri can't even taxi! I can only imagine the stench out of your face hole if the engine situation were reversed.
