Ukraine’s Progress-Ivchenko unveils lightweight fighter engine in China, ASIA PACIFIC
Ukraine’s Progress-Ivchenko design bureau has shown a completed design concept for a new fighter engine as speculation grows that China is working on a lightweight, single-engine fighter to supplement the heavier Chengdu Machine 2001/J-20 fifth-generation fighter prototype.
Designated the AI-222-95F, the engine is a 9,500 kg afterburning derivative of the AI-222K-25F that powers the Hongdu L-15 Falcon jet trainer. The engine “is a completed design that can be developed into a prototype engine within three years”, a Progress representative told Jane’s at the biannual Aviation Expo China held in Beijing in late September. “The engine was developed with the idea of being fitted to a new lightweight fighter that could be designed and built either in Russia or in China.”
