飞行包线对飞行安全影响研究

The Research on the Flight Envelope of Aircraft Effect on Safety of Flight

论述了军用飞机飞行包线的定义、变化、来源、分类、构成、功用和影响因素,详细分析了飞行速度、飞行高度、飞行过载、大气状况、飞机构型、发动机使用限制等因素对飞行包线的限制和影响,结合国内资深飞行员的飞行经验,得出只有采取针对性措施,才能有效保证飞机不超出飞行包线范围,从而降低飞行员操作失误,对保证飞行安全有很好的指导作用,展望了现代飞机飞行包线的扩展远景。

To fly in the flight envelope is the primary condition of safe flight of all kinds of aircraft. This paper discusses the definition, variation, source, classification, constitution, function and influen- cing factors of the flight envelope of military aircrafts. Besides, the constraints and effect of factors such as flight velocity, flight altitude, flight g-load, atmospheric conditions, aircraft configuration and engine hours on the flight envelope are analyzed. Combined with the experience of senior domestic pilots, it is concluded that only by taking specific measures can the aircraft be effectively guaranteed not to exceed the range of the flight envelope, thus reducing the pilot＇ s operational errors. The result of the research provides a good guidance to flight safety and look into the expended future of flight envelope of modem aircrafts.
