摘要
为了实现对高速旋转弹进行低成本的二维弹道修正,采用在高速旋转弹弹头加装两对固定鸭舵的二维弹道修正原理和减旋技术。为了研究鸭舵的减旋能力,建立了二维弹道修正弹模型,对不同弹丸飞行速度、攻角、舵偏角对应的导转力矩进行动力学和运动学联合仿真,以及对导转力矩在全弹道进行数值计算。结果表明,固定鸭舵能够满足对高速旋转弹修正减旋要求,研究结果对二维弹道修正技术研究有较好的参考作用。
In order to correct high-speed rotation of two-dimensional trajectory correction projectile and realize two-dimensional correction at low cost, according to two-dimensional trajectory correction principle and anti-rotation technique, high-speed rotating projectile was fixed with two fixed canards in warhead .In order to research anti-rotation ability of canards , the two-dimensional trajectory correction projectile model was established .Different projectile flight speed , attack angle , rudder angle were included in dynamics and kinematics simulation , and rotation moment in the whole trajectory was calculated .The results indicate that the fixed canards can satisfy modified anti-rotation re-quirements of high-speed rotary missile.The results offer reference for further research of 2D trajectory correction.
