Range Optimization Based on Engineering Design Method

Range is an important performance index of ballistic missile.Flight program selection has great effect on adequately improving range and exerting carrying ability.For this problem,advantages of easy realization and less computation of engineering design method can be adopted to transfer the prime control functional problem,which takes the flight program as the design object,to a problem of parameter optimization.Based on this,the trajectory motion model and optimization model are established.And the maximum range trajectory is obtained through parameters optimization by particle swarm optimization(PSO) algorithm.The results show that range optimization is simple and feasible based on the engineering design method.Furthermore,the optimized parameters have remarkable effect on improving range and exerting carry ability by using PSO algorithm.The extended-range and increased carrying ability play an important role in enlarging the target coverage of missile weapon.
