Mil.huanqiu.com says in its report yesterday that according to a Russian website’s report on October 25, China has entered into a contract to buy 100 AL-31 and 100 D-30 aircraft engines from Russia to be delivered in three years.

Based on the above Russian report, Vassily Kashin, a Russian senior research fellow at the Center for Comprehensive European and International Studies at the National Research University—Higher School of Economics, believes that China has to import Russian aircraft engines as it is not satisfied with its homegrown aircraft engines.

According to CCTV’s report in early May, one existing production line in a WS-10 engine workshop was able to produce 100 WS-10s a year. The workshop is operating 24 hours a day due to the large demand for the engines to be installed in Chinese advanced fighter jets. From that report, we see that the import of 100 AL-31s in three years is negligible compared with the demand.

WS-10 weighs 1,706 kg, has a thrust of 138 kN and a thrust-weight ratio of 8.1. Its operation is quite stable to satisfy the needs of advanced Chinese fighter jets including J-10, J-11, J-15 and J-16.

J-20 Uses Very Powerful Chinese Homegrown Aircraft Engines

The mil.huanqiu.com report says that a video footage more than 4 minutes long taken during the National Day festival (a week around October 1) shows two J-20 doing highly difficult maneuvers in formation including looping in succession, vertical climb-ups and sharp 180 degree turns. According to military expert Du Wenlong, to do a sharp 180 degree turn, a J-20 must use a Chinese homegrown vectored thrust engine. He believes that the engines J-20 is using are at least a little better than those used in fighter jets abroad.

According to Du, there are no engine supply problems for J-20 now.

    Considering the quantity of the Chinese fighter jets entering service in the last couple of years alone, we can already conclude that Chinese turbofan engine productions is doing fine. Otherwise the whole fleet will be grounded. But this simple fact is often burried under the barrage of Western media propaganda that Chinese engines were unreliable. However, Western media own propaganda is actually working against themselves. By saturating the media that Chinese engine is unreliable, their intelligence were actually fooled by their own misinformation. As the result, the emergence of Chinese fleets is a surprise to them, which they call ‘build up’. No one in the world, not even the American before the F-35, developing a fighter jets without working engine. Otherwise, how would they balance properly the mass ratio toward thrust. Obviously China already had at least working base-model WS-15 engine when they decided to develop J-20 back in 2010. Based on their reported breakthrough on metallurgical test later, suggests that they are merely upgrading the base-model engine for better performance of the already working prototype. Only the American built the F-35 without having a working engine ready. It is a sign of how the American has gone so backward on their R&D discipline. Obviously, the shortage of Chinese scientists willing to work on the project had forced them to result to bluff, with embarrassing consequences.

    China is accustomed to Russian engines, understands the capability and technical layout of its functions. Its normal precedence to trust the Russian engines as a back up due to lack of supply to meet demands for All the Js except the J-20 in China.

    China’s aviation engine producers could have a shortage of experienced engineering technicians. The most important result for China’s aviation is that producing state of the art engines is no longer a bottleneck.

    And with state of the art engine installed for the J-20, we may see its appearance at the Zhuhai Air Show next week. It would be a prestigious show for China’s top aviation engineers and experts. China’s aviation stealth technological prowess has come of age.
