自40年代初燃气涡轮发动机问世以来,飞机的速度、高度和机动性发生了历史性飞跃,并跨入了超音速飞行的新时代。到21世纪初,战斗机及其发动机经历4次更新换代。目前现役主力机种是第三代,推重比为8一级,还在不断改进改型;第四代推重比10一级发动机已进入首飞,预计2003年前后装备部队;第五代推重比15～20一级发动机,可望在2020年研制成功。世界航空发动机技术呈加速发展态势,面对21世纪和知识经济时代,如何抓住机遇、加快发展,本文提出几项建议供领导参考。 Since the advent of gas turbine engines in the early 40s, the speed, altitude and maneuverability of the aircraft have taken a historic leap forward into the new era of supersonic flight. By the beginning of the 21st century, fighters and their engines underwent 4 upgrades. Currently the main type of active service is the third generation, the push-to-weight ratio is 8 level, is still improving retrofitting; fourth-generation push-weight ratio 10 has entered the first flight of the engine, is expected to equip troops around 2003; fifth-generation push to weight ratio 15 to 20 an engine, is expected to be successfully developed in 2020. In the 21st century and knowledge-based economy, how to seize the opportunity and speed up the development of the world’s aero-engine technology, this paper put forward several suggestions for the leadership reference.
