Reduce Air Rockets Spread Method And Its Optimization

In this thesis .based on the accurate six freedom degrees kinetic equations of the air rocket, an optimizing model of calculating air rocket dispersion is established . The influence of double-push accelerated velocity ,spin-rate regularity and unfolding fins on air rocket dispersion and the mechanism of decreasing of air rocket dispersion are also studied respectively . Using method of SUMT and powell , the thesis carries out optimization design for air rocket with double-push accelerated velocity and spin-rate regularity , which dramatically decreases air rocket dispersion . In the end , some valuable conclusions are achieved for application .
