飞行失控的向量空间建模与应用研究

Vector Space Modeling of Flight Loss-of-Control and its Application

为对飞行失控进行分析,研究了采用决定性参数分析飞行安全状态的方法。建立了安全飞行向量空间,并划分为5个包线子空间,将飞行包线转化为相同形式。采用安全性函数表示飞行失控深度,确定安全面并求解飞行失控发生时间的研究方法。对一次飞行事故进行了研究,结果表明,该方法能够对飞行失控进行定量分析。

The flight safety status is researched adopting the decisive parameter, and loss-of-control （LOC） is analyzed. The vector space for flight safety is set up, and the space is divided into subspace composed of five fight safety envelopes. The envelopes are changed to uniform. The safety function is put forward to denote the deep of the loss-of-control, confirm the safety face, and calculate the time of loss-of-control happens. A flight accident is researched, and the results show that the method can quantitatively analyze the loss-of-control.
