地形冲突回避控制原理的研究

地形冲突是指飞行器与地面之间的相对位置发生矛盾,可能导致可控飞行撞地事故(CFIT)发生的潜在危险现象。在飞机飞行过程中,飞行员瞬间丧失知觉是飞行员自身因素导致飞行事故的一个重要问题,这个问题困扰着所有飞高性能战斗机的空军及其飞行员人员。丧失空间方向感又是一个更为严重的问题,它影响着空军和民航的飞行员人员。为了防止由于自身因素引起的飞行员和飞机的巨大损失,研究自动地形冲突回避系统是必要的。通过对地形冲突回避控制原理三种方案的研究分析表明:一种不需要飞行员涉入,一种需要飞行员涉入,即所谓人在回路之中,一种需要对外发射信号。

The Research for Terrain Impact Avoidance Control Principle

Terrain impact is the conflict of relative position between the airplane and ground, which would cause CFIT accident. In flight, G-induced loss of consciousness is a human factor problem that plagues all air forces that fly fighting aircraft with high performance. Spatial disorientation is a more serious human factor problem that affects not only the military but also the commercial aviation. In order to avoid the tremendous loss of pilots and aircraft because of human factors -related mishaps, it is necessary to research the ground automated collision avoidance systems. By studying the principle of ground automated collision avoidance, three designs are concluded： one requires no pilot intervention; one requires pilot intervention, namely the pilot in control loop; the last one needs transmitting signal outward.
