当高性能飞机飞行在高过载或复杂地面环境条件下, 飞行员产生的意识丧失或对空间位置及姿态的误判将会造成机毁人亡的严重事故。飞机的自动防撞技术(ACAT)是避免该类事故发生的最有效途径。介绍了飞机对地自动防撞技术的发展, 以及对地自动防撞系统(Auto GCAS)的功能要求和原理, 并给出了对地自动防撞系统(Auto GCAS)的构成、防撞算法的结构。为了直观地研究飞机对地自动防撞系统, 提出了基于MATLAB与AVDS飞行仿真软件相结合的仿真验证系统。系统利用MATLAB与AVDS仿真软件的可视化仿真技术显示飞机对地自动防撞系统飞行仿真效果。仿真结果表明, 该仿真系统具有良好的实用性, 具有一定的应用价值。
When flying over the complex terrain in bad weather, the Loss Of Consciousness(G-LOC) or misjudgment for space and attitude of pilots of aircrafts with high performance would result in fatal accidents.The aircraft′s automatic collision avoidance technology is the most effective way to avoid such incidents.This paper introduces the development of the aircraft automatic collision avoidance technology(ACAT), as well as the functional requirements and principles of the Automatic Collision Avoidance System (Auto GCAS), and presents the composition and algorithm structure of the Auto GCAS.To study aircraft ground automatic collision avoidance system visually, this paper proposes a simulation testing system based on the combination of MATLAB and the AVDS flight simulation software to display the flight simulation effects of automatic ground collision avoidance system.The simulation results show that the simulation system is practical and of great application value.
