Chinese J-20 stealth fighter with indigenous engine conducts maiden flight

China has conducted the maiden flight of its J-20 fifth-generation stealth fighter powered by indigenous Shenyang WS-10B turbofan engine today.

The aircraft with serial number, 2021 took off at 12:57 local time from an airport in Chengdu and the flight lasted 27 minutes.

Currently, the J-20 fighters are powered by Russian AL-31F engines which developed by Saturn NPO originally for the variants of Sukhoi Su-27 air superiority fighter.

The WS-10B engine is a variant of the WS-10 engine developed by Shenyang Liming Aircraft Engine Company.
