According to Russian Military-Industry Courier weekly and US Aviation News Weekly speculation, China has obtained from Russia the technology for a VTOL fighter jet, and will probably develop a VTOL version of the J-20 stealth fighter jet.
The technology was formerly used in Russia’s Yak-141 VTOL fighter.
A prototype of the R-79-300 engine used in the Yak-141 was sold to China in 1996. In 1998, Russia transferred technology related to the nozzle of the engine to China.
The engine is a vector thrust turbofan with maximum thrust of 8,994 kg, which can be raised to 15,500 kg with additional boosting. Its nozzle can turn 95 degrees downwards with a lifespan of 1,500 rotations.
The Yak-141 is able to take off within a short distance of 5 metres.
It has set many world records for VTOL fighters, including climbing to 12,000 meters in 116.2 seconds with effective load of 2,000 kg and 130.5 seconds with 2,000 kg, and a climbing speed of 250 m/s from the height of 3,000 to 8,000 metres.Source: qianzhan.com “China has mastery of key technology that may probably enable it to develop VTOL version of J-20: foreign media” (summary by Chan Kai Yee based on the report in Chinese)
