Oh god, the part of the engine is classic US journalism.



Just watch, this paragraph alone is going to be quote for the next 20 years to death, to support the evidence that Chinese are cannot do anything but stealing, and they are not even good at stealing old American technology.

Can't blame them, so long as China still reliant on Russian import and no Chinese export jets (commercial and military alike) comes with Chinese-made engines, there's nothing solid to rebuke such criticism.

I wonder how many Americans now regret that decision and wish the F23 won instead.

The best airplane won, the Raptor is the more effective combat aircraft, the YF-23 has no TVC, smaller weapons bays, and is not supermanueverable in the sense of the F-22, in fact the YF-23 has a ruddervator like the Beechcraft bonanza, not an optimal layout for a supermanueverable fighter aircraft, in which the ability to make quick pitch transitions is the key to turning the aircraft inside your opponent, its Kool in a geeky kind of way, but I will acknowledge that it was slightly faster and stealthier but not enough to put it on top of the Raptor!

But this is far from what the paragraph that being quoted was saying, it didn't even mention Russia, in fact it says the engine they are using is a failed reverse engineered version of 1970 US technology. I am not aware if any of Chinese engine is basing on US technology. At least the one used in J-20 of J-31.

Come on Jack, here you go again.

No need to make such rash and general comments that are so judgemental of American people in general.

By doing so, you are 1st, insulting Americans who certainly are not that way and driving them away from SD...and 2nd, giving a bad impression of youerself to others.

My advise would be to scale back on the attacks like this, they really add nothing to the discussion and are certainly not professional.

Kinda like a 45 rpm record with a scratch in one spot, in one spot, in one spot, in one spot, in one spot, in one spot, in one spot, in one spot, come on guys, lets get past this, I've said all along the F-60 is a gorgeous airplane and would put Shenyang back on the map, and yes if it makes you feel better we are all just shakin in our combat boots, one rebuilt Naaaahhh, I'm not gonna insult my Chinese friends with a comment, I am sorry to my true friends, but boy whats out on the table next?

The paragraph is likely referencing the WS-10.

Engineer once pointed out that the WS-10, if it was derived from anything, is likely derived from the CFM56 engine core, which was imported into China from the US in the early 80's. In this context, most of Pike's statement matches up well with the facts. The only part that doesn't match well is where he states that, "It's still no good." As everyone here is aware, the WS-10A is definitely "good" enough to be used in large numbers.

Thanks for the correction, I always assumed they are based from AL-31 than anything else. But just how much of WS-10 is consider to be CFM56 technology anyway?

Chinese engines have their origins in British designs. China forgave the Brits for the opium wars in exchange for the technology and other friendly gestures. Chinese engine development was active since the 60's. It wasn't a priority for them until recently when their economy and industry attained a size suitable for military expansion. Now, you can be sure Chinese engine development is going full steam ahead. Chinese technology comes from multiple sources. Anyone doing business with China is required to provide some sweeteners. US technology is not hard to get if China want it, but it isn't always wanted because it isn't always the most efficient.

I'm pretty sure only the WS-10 engineers know the answer to that. The moment words like, "Based on", and, "Derivative of" are used, it's anyone's guess, lol.
