摘要
为了计算面对称旋转导弹的刚体弹道,根据面对称旋转导弹的特点,建立了其刚体弹道模型,定义了模型中的坐标系并给出了各个坐标系之间的转换关系,在此基础上得出了角度的计算公式,分析了风对旋转导弹运动的影响,在弹体坐标系下计算了气动力和气动力矩,解决了面对称旋转导弹弹道精确计算问题。
In order to calculate the rigid body trajectory of rolling missiles with plane-symmetry, the rigid body trajectory model is established according to the characteristics of roiling missiles with planesymmetry. Based on the definition of coordinate systems and the transform relation of various coordinate systems, the computing formulas of angles are derived. The influence of wind on roiling missiles motion is analyzed, the aerodynamic forces and moments are calculated in the body coordinate system, and so the problem of accurately calculating the trajectory of rolling missiles with plane-symmetry is solved.
