第四代戰鬥機F-22即將進入飛行試驗階段,預計在2002年可投入使用。與之配套的動力裝置——F119加力式渦扇發動機也正處於全面工程和製造研製階段,到1997年將提供首臺生產型發動機。本文將對這種動力裝置的設計要求、技術指標、採用的新技術和研製進展作一簡單介紹。設計要求發動機是飛機的心臟,是飛機性能的决定性因素,因而對飛機的戰術技術要求决定了對動力裝置的設計要求。下面,通過對第四代戰鬥機的戰術技術要求來看對F119發動機的設計要求。 Fourth-generation fighter F-22 is about to enter the pilot phase of the flight and is expected to be operational in 2002. With its accompanying power plant - F119 afterburner turbofan engine is also in full engineering and manufacturing development stage, to 1997 will be the first production-type engine. This article will make a brief introduction on the design requirements, technical indicators, new technologies and development progress of this kind of power plant. Design requirements The engine is the heart of the aircraft and is the decisive factor in the performance of the aircraft. Therefore, the tactical technical requirements of the aircraft determine the design requirements of the power plant. The following, through the technical requirements of the fourth generation of fighter tactical aircraft F119 engine design requirements.
