大型水陆两栖飞机海上最优搜索航路规划算法

Optimal algorithm of searching route for large amphibious aircraft

针对大型水陆两栖飞机的飞行特性和远海搜索救援能力不足的问题,研究设计了海上最优搜索航路规划算法,使其能够在最短时间内完成规定海域的搜索。针对大型水陆两栖飞机的特性参数,结合漏搜率和复搜率的要求指标,将原搜索航路规划问题转化为格点的离散规划问题。本文最优搜索航路规划算法在动态规划的基础上引入回溯路径指标,能够满足复搜率的要求。数值仿真分析结果表明:相对于传统的搜索路径方法,采用本文算法求得的最优航路方案具有更好的性能指标。

To enhance the search and rescue capacity,this paper represents an optimal algorithm of searching route for large amphibious aircraft to complete its search tasks within minimum time based on the flight characteristics of aircraft.The search route planning problem is transformed into a discrete programming problem considering the indexes of both missing search rate and duplicate search rate.The optimal route planning algorithm applied the route backdate indexes to satisfy the duplicate search rate.Meanwhile,the planned routes satisfy all constraints,such as the maximum overload,no-flying zone and so on.The numerical simulation results indicate that the performance indexes of the optimal routes calculated by the optimal route planning algorithm are better than the ones obtained by the traditional search route planning methods.
