滑翔增程炮弹弹道仿真与优化设计

根据滑翔增程炮弹的空气动力特性和飞行弹道特性,通过对滑翔弹道的理论分析,采用控制鸭舵技术,实现炮弹的增程。经过仿真优化可以得到最佳初始射角、助推发动机的最佳点火时间及作用时间、鸭舵的最佳展开时间以及控制系统进行飞行姿态控制所需的最佳摆动角曲线,理想情况下最优滑翔控制模型可使射程达到不进行滑翔控制时射程的1.5-2倍,所得结果对滑翔弹丸的气动力设计及控制系统设计具有一定的参考价值。

Study of Trajectory Simulation and Optimum Design of Gliding Range - Assisted Projectile

Based on the characteristic of aerodynamic force and flight trajectory of gliding range - assisted projectile, the technology of rudder control is used to increase the range of projectile by the theoretic analysis of gliding trajectory in this paper. We can obtain the optimal preliminary angle of fire, the optimal ignition time and work time of booster engine, the optimal outspread time of rudder and the optimal curve of swing angle, which is used to control the flight pose of projectile. The optimal model of gliding control can increase the range obviously. The results are meaningful to the design for gliding projectile regarding the aerodynamics and the control system.
