复杂地形下直升机救援最佳飞行路径分析

Analysis of the Best Flight Path for Helicopter Rescue Under the Complex Terrain

直升机救援是应急救援体系的重要组成部分。直升机救援常常在复杂地形下进行,为了使直升机以最少的时间到达救援点,则需要求得直升机的最佳飞行路径。本文选取西南某地区典型复杂地形;然后利用SuperMap软件构建直升机救援飞行路径网络,并以时间为阻抗因子对飞行路径网络进行赋权;最后采用Dijkstra算法求得在复杂地形下直升机救援的最佳飞行路径。

The helicopter rescue is an important component in emergency rescue system. Helicopter rescue often happens un- der complex terrain, in order to make the helicopter reach the rescue point in the least time, the best flight path must be ob- tained. This paper first selects a typical complex terrain in the southwest. Then builds a helicopter rescue flight path network with Supermap software, and takes time as impedance factor to endow the weight of flight path network. Finally obtains the optimal flight path for helicopter rescue under complex terrain by using Dijkstra algorithm.
