Chinese Engine Development
- Thread starter jackbh
- Start date
Why can't China make something like the PW-1120 engine for the JF-17 Thunder and the Shenyang J-31. The PW-1120 is essentially a downsized P&W F-100 engine meant for the Israeli Lavi. Just build a downsized WS-10 that share a lot of the same components. Rather than to develop a whole new engine like the WS-13 which is more in line with the GE F-404 or GE F-414.

It is wrong terminology or written by someone who doesn't have a clue what they are writing. We know for sure that the Chinese engineer extend the life of Al 31 to 1500 hr between overhaul.So by deduction they should have the same comparable MTBO for WS 10 I never heard the term life expectancy for engine. Even you source quote MTBO) 1000 hr which is again not true Indian experience is 900 hr
Be careful when you quote from Wiki like this statement
According to Saturn`s Victor Mihailovic Chepkin, chief designer of the 117 and 117S engines, the Chinese WS-10 was developed with the aid of the AL-31`s maintenance technical documentation. China can domestically produce most AL-31 parts for its own jet engine programs, but still import turbine blades from Russia
we know this is untrue!. We know that the origin of WS 10 is CFM 56

hehe, some times I am thinking that I can create a wiki page or update a wiki page with my data and then use it to back my assertion as evidence. A self-proving loop.
OMG....you got your info from wikipedia?
I have seen wiki pages being changed back and forth by people of different beliefs, and even rumors being cited as "evidence", such as "there are rumors", "it is speculated", "however this cannot be verified". These words even show up in articles of science, tech and engineering. just "amazing".

WS10 is running how many J11B/S ? Probably over 200
That's 200 x 2= 400 engines
What's average flying hours for Flanker regiment? Say 150-175
That's well over 70,000 flying hours per year
How many years flanker been using WS10 well quite a few
Pretty safe to know that WS10 is well established

I have a question regarding military and civilian turbofan: china has bought su35, probably to reverse engeneering 117s, which combine good thrust, long lifespan and tvc(which usually reduce life of the engine) but already have leap1 engine for c919. The materials used for these engines are probably very different or they are expected to be similar?

There are a lot of assumption in your post.
- We were told every year for nearly a decade that China is buying/brought Su-35. So far, there has been no indication of that being a fact. We simply roll our eyes collectively whenever we hear sales of Su-35 at this point.
- To reverse engineer an engine would require two decades of work, as was the case with WS-10. By the time that was done, the engine is no longer cutting edge. Also, 117S is just an "over clocked" version of Al-31, which is in the same generation as WS-10. There is no incentive for China to copy one.
- With engines, the biggest deal lies in materials. You can't reverse the ingredients and methodologies from cakes you brought from stores, and the same is true with engines. Paradoxically, if you can figure out the ingredients and methodologies, you would already have all that is needed to become a master baker and no need to copy. With WS-10, China already figured it out.
- To answer your question, LEAP is a Western engine meant for civilian use, whereas 117S is a military engine. Aside from such obvious difference, LEAP is way more advanced. There is no comparison.
To admit if I read such posts I sometimes get angry ... at least a bit !
First of all: why do so many peoples still think it is so much easy to "copy" or "reverse engineer" anything ? These trash-reports esp. from certain US-media that the CHinese stole some terry-bytes from LM's PC in order to "copy" the F-22 and F-35 as the J-20 and J-31 ! Plain stupid, pure bullshit ! ... but it seems as if some readers simply only like to read such stuff.
That does not deny the fact that the CHinese are surely interested to take a deeper/closer look onto and into this engine, but again to copy it ...
Anyway... similar to what "Engineer" explained ...
.. however:
Why to You still question this deal??? It has been confirmed by the Chinese MoD, so even if some might don't like it or understand the reasons behind, that deal is done.
By the way ... here's an interesting news !
