Simulation of Route Planning for Hypersonic Aircrafts
B Wang · Jisuanji fangzhen · 2015
In order to enhance the ability of penetration for hypersonic aircrafts,an ant colony optimization algorithm with improved search strategy is presented to solve the route planning problem. Different from the ordinary adaptive ant colony algorithm,the proposed algorithm not only considers the relative position of the current node and the destination node,but also considers the speed direction of the aircraft at the middle track point and the constrants of the minimum turning radius. The adjacent search nodes are further decreased,so as to improve the algorithm speed. Simulation is carried out for the case of the target node relative to the initial node in the first quadrant. Simulation results show that the improved algorithm is effective and reasonable. In addition,the minimum turning radius of the aircraft is considered to ensure real and effective planning trajectory.
