Optimization of Glide Trajectory for Aerial Bomb With Morphing Swept Wings
摘要
Abstract
To improve the gliding ability of aerial bomb with morphing swept wings, the optimization of glide trajectory was studied. The aerodynamic characteristics of aerial bomb were analyzed. According to the mathematical model of optimization trajectory, the fit trajectory law was considered as an optimal control problem. Pontryaghin maximum principle was used to obtain necessary condition of optimal trajectory. By means of the particle swarm optimization（PSO）, the control law of attack angle and sweepback was optimized, and a design method based on double control variables was proposed. Numerical simulation results show that, under satisfying constraint condition of state equation, the range of the aerial bomb controlled by double control variables is longer than that with fixed form and controlled by single variable evidently. The opti- mization results accord with the distribution rules of aerodynamic characteristics, and the method of optimizing trajectory using the optimal control and PSO was feasible.关键词
