对利用一对鸭式气动布局的舵片来修正弹丸姿态的简易制导迫击炮弹进行了研究,分析了弹丸在有控飞行过程中所受到的力和力矩,建立了6自由度刚体弹道模型并进行了仿真,得到了弹丸在有控状态下飞行的弹道曲线,并在舵偏角为0°和10°时进行了模拟打靶,分析了其攻角曲线变化规律。仿真结果表明:该弹道模型能够有效反映出弹丸的运动规律,为后续分析简易制导迫击炮弹弹道特性的研究提供了理论依据。
This paper studies a simple guided mortar shell that uses a pair of ducks with aerodynamic layout of rudder blades to correct projectile attitude and analyzes the force and moment the projectile receives during a controlled flight. A rigid body ballistic model with six degrees of freedom The trajectory of the projectile flying in the controlled state was obtained. Simulations were carried out when the deflection angle of the projectile was 0 ° and 10 °, and the variation of the attack angle curve was analyzed. The simulation results show that the ballistic model can effectively reflect the movement law of projectile and provide a theoretical basis for the subsequent analysis of ballistic characteristics of simple guided mortar projectiles.
