自由飞行下基于IPS算法的碰撞风险研究

Study on Free Flight Collision Risk Based on Interacting Particle System

自由飞行是解决空域拥挤问题的一种有效飞行模式。随着通信、导航、监视(CNS)技术的不断进步和自由飞行理论的不断完善,自由飞行将会使飞机由被动指挥向自选最优路径转变,能够明显提高空域的容量和飞行的效率。在评估自由飞行环境下飞机运行的安全性时,需要行之有效的碰撞风险评估方法。首先考虑通信、导航、监视(CNS)性能对飞机定位误差的影响,在执行飞行冲突解脱命令过程中引入相互作用粒子系统(IPS),提出一种自由飞行下飞机碰撞风险评估算法,最后结合目标安全水平寻找最优最小安全间距。算例表明,算法能够快速有效计算自由飞行下飞机间碰撞风险,具有可行性。

Free flight is a kind of flight mode that aimed at solved the problem of air route congestion in countries. With the improvement of the Communication,navigation and surveillance technology（ CNS）,the free flight will shift from passive conducted to optional optimal path,improving the capacity of airspace and the flight efficiency. When to test the security of free flight,we need an effective method to verified it.This article firstly consider the deviation impact of communication,navigation and surveillance,and introduced an algorithm called Interacting Particle System when implement the conflict resolution process to calculate collision risk in free flight. At last,we calculated the minimum safety distance in comparison of the target safety level. Numerical examples show that the result is feasible.
