Exciting Times for Chinese Aircraft Engines!

[no smoking]

Most of the engineers in the photos look 30 to 35 years old，

So the question is: where are those of 35-50, especially those over 40+, as they are supposed to be the backbone of a team.

According to the group photo tradition

the middle row is the key leaders. They are 40+ years old

Losing older members to private industries in China is not a bad thing. Just looking at the number of private space firms tells me that private sector is pretty strong even in heavy engineering like aerospace. Now losing them to emigration would be -- it was an issue in the 1990s and early 2000s.

The MA700 project was thought dead after its Pratt and Whitney engines were never delivered (P&W is Canadian so it is suspected that it is an US-pressured embargo.)

But then it was spotted in satellite pictures with engines at the testing site in Xian.

And few days ago, we now know that it actually flew!

The question is what is powering it?

Most likely a variant of the WJ-6 turboprop which is a mature engine powering a lot of types (Y-12, Y-7, Y-8, Y-9.) The ultimate engine for it is now the AEP500.

 

[SexyChineseLady]

Much speculation that it might actually be the AEP500. But it seems unlikely because the AEP500 is pretty new and in testing so they would never couple that with a prototype airframe. It would be a big game changer if true.

The AEP500 has 5000kW of power compared to 3200kW of WJ-6C and the 3700kW of the originally intended PW150C!

From a discussion on the recent Y-20 fleet to Serbia. Y-20 is a great platform and will end up using and validating three Chinese engines -- WS-18, WS-20 and CJ1000!


----------------------------------------------------
google-translated:
Apr 11 There are already more than forty Y20As. Four of the full-status Y20Bs are already in testing. Mass production should be Y20B. Y20A uses turbofan 18 and Y20B uses turbofan 20. The Y20X may be used in the CJ1000 series of engines in the future.

Can u please provide the development cycle I mean history of y-20 in some other thread

WS-20 might be targeted for the C919 if it ever becomes a military platform like for AEW or MPA. There is also another high bypass engine in development for C919 -- CJ-1000: https://mobile.reuters.com/article/amp/idUSKBN2AX0OZ China outlines push to develop domestic engine for C919 jet in...

From a China watcher in Japan:

第二北大路機関 J-20戦闘機用は新型WS-15エンジンによる評価試験で良好な成績を収めたと中国CCTVが報じた　鞍馬の考

China's CCTV reports that the J-20 fighter, known as China's stealth aircraft, performed well in evaluation tests with the new WS-15 engine. The J-20 fighter has partially started mass production and is being developed in parallel, and while operating the early manufactured aircraft as a technical demonstration machine in the actual combat unit, it is a complete type that incorporates all the performance such as anti-aircraft combat.

Compared to the conventional WS-10 engine, the WS-15 engine has a significantly increased engine thrust from 15t to 18t, and especially because the J-20 fighter is twin-engined, the thrust has been increased from 30t to 36t. At the same time, it is said that it will be possible to improve supercruise cruising ability and maneuverability of the aircraft

All I am seeing is building a fifth gen aircraft is not an easy task
Even China who is manufacturing powerhouse is taking such time to build a quality 5th gen aircraft
Imagine how much time is gonna take fora country like India
Our developers have given an ambitious timeline but we could say it could stretch atleast a decade from their notified timeline to build a quality amca

No, not easy. That is why China has multiple stealth fighters (J-20, J-35) and especially multiple engines -- WS-10C, WS-15, WS-13E, WS-19 -- to mitigate risk.

FC-31 came out of the losing design that Shenyang AC put up as competition to Chengdu's J-20. They kept it around for a decade and finally found a customer for the Navy. Without the FC-31 it would have taken a much longer time to design and test a lighter twin-engined stealth aircraft needed for carriers.

More importantly, multiple engine projects allow China to start mass producing the J-20 and later the J-35 with interim engines before the final engines are ready. The WS-10C has allowed the J-20 to at least partially go into mass production and get the lines into shape before the WS-15 is ready. The WS-13E will serve the same purpose for the J-35. You are able to find and fix faults in the mass production process only when it is running -- that is what the interim engines allow you to do.

For India, I think the process is the same. You would have the plane and intended engine running in parallel projects. The one difference is the lack of a domestic interim engine.

I assume the AMCA will depend on an US engine, F414, before the new 110kN engine is ready. So you will need to import engines which may or may not inhibit mass production. Then when the new engine is ready only then will you begin to test out the final production chain with that engine.

AMCA is very much like the J-35 project which also has an intended 110kN engine (WS-19.) The key difference is the J-35 will have the WS-13E interim engine and will likely already be in mass production by the time the WS-19 is ready.

CJ1000 working model! It was supposedly flown in China's IL-76 flying testbed some time in April!

CJ1000 is slated as the domestic engine for C919.

 

[SexyChineseLady]

CJ-2000AX has entered the verification machine bench test stage. Low-voltage component telemetry system hardware configuration is currently in bidding stage. CJ2000 project is barely a year behind CJ1000 even though it started much later as it incorporates advances developed by the latter.

CJ2000 is the domestic engine for the CRC929.

So for the JV of CR929 between Russia and China. If Russia fact we won't get RR engine, the CJ2000 will be the only option?

Yes, most likely PD35 for the Russian engine option and CJ2000 for the Chinese one. Though there is possibility that if they separate final production between Russia and China, RR can still supply the aircraft built by Comac. Anyways, production is still some times away. Politics might change by then.

Beijing ushers in the age of Chinese super carriers

The launch of Beijing's third aircraft carrier, CNS Fujian, was a powerful symbolic moment in China's relentless arms buildup, with work also underway to forge a world-class air wing.

www.flightglobal.com

The original J-31/FC-31 was powered by two Klimov RD-33s, but the J-35 is powered by two Chinese WS-19s. The WS-19 is understood to produce 24,700lb (110kN) of thrust, which would make it about 10% more powerful than the GE Aviation F414, the powerplant for the twin-engined Boeing F/A-18E/F Super Hornet.

Why "understood to Produce"? Do not you guys have specifications of your own engines? You had shouted very loud that WS 10 will be used in J 20 but ultimately you had to opt for Al31. You guys have a habit of talking big moth. Chinese posters on PDF said that your new rocket is capable of delivering 14 tons in GTO but the fact is that you guys have never delivered more than 5.5 ton Payload in GTO with your rocket. First two of which failed and satellite fell into sea.
