Abstract: Air data system provides the aircraft with critical flight information: altitude, altitude rate ( vertical speed), airspeed and Mach number, which are used in flight control and navigation. 大气数据系统可为飞机提供高度、高度速率(升降速度)、空速和马赫数等飞机飞行状态的重要信息,并应用于飞控和导航系统中。
Critical conditions of fireball lift-off, effects of high altitude environment and fireball gliding are also analysised. 还讨论了火球升离地面的临界条件、高空环境对火球直径的影响和火球随风漂移等三方面的问题。
