应用时间裕度法评估人-机系统飞行安全

The Method of Flight Safety Time Margin to Evaluate Flight Safety of Pilot-Aircraft System

采用临界参数确定飞行风险,提出了安全飞行时间裕度概念,根据安全飞行时间裕度和飞行员操纵干预滞后时间评估飞行安全。研究了不利因素影响下的飞行员操纵干预滞后特性。给出了临界参数分别为过载和高度时,飞行安全时间裕度的计算方法。实现了对人-机系统飞行安全的定量评估,并给出了风险概率。

Flight risk is judged applying critical parameters. The conception of flight safety time margin is put forward. According to the parameters of flight safety time margin and pilot delay time, the flight safety is evaluated. The delay property of pilot manipulation is researched when the aircraft is in upset condition. The calculation method of flight safety time margin is given when critical parameter respectively is load and height. Flight safety of pilotaircraft systems is evaluated quantitatively, and the risk probability is given.
