China Could Make 5th Gen Engines By 2021

[UKBengali]

China has already tested its 5th generation engine WS-15 in 2010, and the results were very close to their goal. The test thrust was already larger than that of the F-119 used on the F-22.

If the J-20 does enter service 2015-2017 then that is when I expect the 5th generation engine to enter mass production.

Any news when WS-15 will be fitted on the J-20?

Going by such reports......one sees not so bright path in the development of J-20 aircraft......whose fullscale induction in PLAAF could be pushed beyond 2022....due to serious snags in the development of WS-15 engine.

Being selective with your own information much?

The first article you posted clearly states an estimated timeframe of 5 to 10 years, so between 2016-2021.

Since the J-20 is expected to enter service between 2017-2019, best case is that the engines will be ready a year early (2016), worst case they'll be 2 years late (2021), but even that isn't too much of a snag because interim engines could be used, like they are doing now.

When the J-20 comes into production.

The WS-15 has already made its first run in 2010, and test results show that it has come very close to its goal. A few years of tweaking should be enough, and it should be available just in time for the first batch production of the J-20.

Replace your J-10/11s with WS-10 first. It'd be a laugh to power the J-20 with a domestic engine if you're still wasting cash on AL-31s.

to make old J-10/11 equipped with wearing-out AL-31s accomodate different demestic engines means restructuring the whole plane, which is far more costly than simply replacing them with newly imported AL-31s. what are we supposed to do, retire them when there's still some good 1000 plus flight hours left?

It amuses.......how easily your types jump onto results/conclusion......yes the article says a time frame of 5-10 years and that's for the development of new engine.....you need to test and some vigorous testing for that engine.........so I would add another 2 years at least in case every thing goes like a fairly tale.........and you don't face any problem........which is generally unlikely......in the process of engine developments......even if you come up with a 5th generation engine by 2021.....I would dare to say it won't be in the class of what other countries (Those having done at least 20 years work on 5th generation engines) would feild.....here in case of 5th generation engine development process you can choose any two of them.

• less time
• required parameters
• reliability

Not to mention the poor state of engine manufacturers in China who fail to come up with required quality levels in mass scale engine manufacturing.......here's a time line of engine development in china.......notice even though WS-10 development was started way back in 1986 and they got full support from Russian manufacturers in order to get similar performance levels of AL-31 it took more than 26 years to enter service and even then there are serious issues with that engines and pilots don't want to see them in their birds........and you are forced to buy AL-31 turbofans again and again.

You don't keep up with news, do you?

All J-11B variants and the J-15 have been fitted with the WS-10A engine. The J-20 flying prototype uses a WS-1X engine with IR reducing tiles.

All the other engines (WS-10B/G, WS-12, WS-13, WS-15) are all in testing. The WS-15 made its first run in 2010 and the test results were very close to the stated goal and already superior to the performance of the F-119.


So, yes, it would be a laugh. For us.

Ever heard of a concept of "parallel development"? WS-10 series and WS-15 are made by different companies.

The WS-15 made its first run in 2010, and the results already exceeded the specifications of the F-119 engine. The WS-15 engine is already very close to maturity and five years is enough to iron out any small issues.

The WS-10 is already installed on J-11B series and J-15, so the "quality issues" you are talking about is mostly your incorrect assumption.
