Ah nonsense. the J16 airframe and engine initially came from Su27, Su30, so my assumption is Chinese planes have similar if not identical characteristics. With years passing China certainly makes progress on airframe and engine. I think the Russians still make better turbofans.
You are truly absurd.
On the one hand, you claim to be an engineer with no ill intentions towards China; on the other hand, without any background knowledge, you launch a massive smear campaign against Chinese products on this forum.
The Origins of the WS-10 Engine:
In 1987, Institute 606 began developing the WS-10 engine. This is the publicly available date; the actual start date is much earlier. The core direction was reverse engineering the core engine of the American CFM-56II turbofan engine, while simultaneously developing the peripheral systems of the core engine independently.
In 1989, the WS-10 engine completed its first test.
In 1992, the first batch of 12 Su-27 fighter jets purchased by China from Russia arrived at the Wuhu Air Force Base in China. Subsequently, China's Flanker fighter jet system began.
China and Russia have never reached any ToT agreement regarding the AL-31 series engines. However, cooperation on a major overhaul facility for the AL-31 series engines was included along with the major cooperation agreement for the Su-27/J-11.
Chinese engineers conducted in-depth technical analysis and reverse engineering through the overhaul work of the AL-31 series engines. These technological capabilities have led to a longer service life for the original Russian AL-31 engine in China than in Russia, with many replacement parts now produced in China, eliminating reliance on Russia.
This experience gained by Chinese engineers in the AL-31 engine field has also been incorporated into the subsequent upgrades and improvements of the WS-10 series engines.
This is the true origin of their connection.
Which PLA jet uses western engine?
Is Russia considered part of the West? (LOL)
