Abstract:
A trajectory forecasting algorithm of the reentry hypersonic glide vehicle is designed based on the linear growth character of the liftdrag ratio of the vehicle. Firstly, by judging the movement equation, the most important thing of the algorithm is discovered, which is that how to predict the liftdrag ratio. Secondly, the simulation of the target trajectory shows the linear growth rule of the liftdrag ratio, the model of the liftdrag ratio variation function is given and the trajectory forecasting algorithm is designed. Simulation results show the efficiency of the forecasting algorithm. This algorithm is important to study the problems on combating with the hypersonic glide vehicle.
