我國殲20隱形戰機服役 並換裝國產發動機

A domestically developed engine will soon power the nation's latest stealth fighter jet, a senior scientist working for Aero Engine Corp of China.

中國航空發動機集團的一位資深科學家日前表示,我國最新型隱形戰機很快將由自主研發的發動機提供動力。

"It will not take a long time for our fifth-generation combat plane to have China-made engines," said Chen Xiangbao, vice-president of the AECC Beijing Institute of Aeronautical Materials. Chen, also a member of the Chinese Academy of Engineering, was referring to the J-20 stealth fighter.

中國工程院院士、中國航發北京航空材料研究院副院長陳祥寶表示:“用不了多久,我國第五代戰機(即殲-20隱形戰機)就能用上國產發動機了。”

"The engine's development is proceeding well. We also have begun to design a next-generation aviation engine with a thrust-to-weight ratio that is much higher than that of current types," he said.

他說道:“發動機的研發進展順利。我們也已經開始設計推重比遠高於現有型號的下一代航空發動機。”

Thrust-to-weight ratio is considered the top indicator of an aviation engine's capability.

推重比被視爲衡量航空發動機性能的最重要參數。

The People's Liberation Army Air Force recently confirmed, without elaborating, that the J-20 has been put into active service.

近日,中國人民解放軍空軍確認殲-20已入役,但未詳細說明。

Aviation industry observers said the plane is still equipped with Russian-made engines due to the lack of a suitable domestically developed engine.

航空業觀察人士稱,由於沒有合適的自主研發發動機,殲-20裝配的仍然是俄羅斯製造的發動機。

Chen said Chinese scientists and engineers are striving to catch up to the world's top players in terms of research and development into cutting-edge aviation engines, but the country still has a long way to go before it can develop and produce world-class engines.

陳祥寶表示,我國科學家及工程師正在努力追趕研發先進航空發動機領域的世界頂級工作者。但是在能夠研發和生產世界級的發動機之前,我國仍然還有很長一段的路要走。
