摘　　要：为研究鸭舵式修正机构的修正能力,以某口径高速旋转稳定弹为模型,研究鸭舵对弹丸的作用力和力矩以及弹丸所受空气动力;并在弹箭外弹道学的理论基础上,利用外弹道学常用坐标系及它们之间的转换关系,构建出鸭舵式修正弹七自由度刚体运动方程的数学模型。基于气动分析结果,采用四阶龙格-库塔方法计算得到修正弹的外弹道参数,得出仿真弹道轨迹,并与实际弹道轨迹进行初步对比。研究结果表明,鸭舵式修正机构的仿真分析与实际弹道轨迹相符,并能够对修正能力进行预测。In order to study the correction ability of canard rudder type correction mechanism,the control force and control torque of canard on the projectile and the aerodynamic force acting on the projectile were analyzed based on the model of a certain caliber high-speed rotating stabilized projectile.At the same time,on the basis of the theory of exterior ballistics of the projectile,the mathematical model of the seven degree of freedom rigid body motion equation of canard rudder type correction projectile was established through the characteristics of the common coordinate systems of exterior ballistics and the conversion relationship between them.Based on the results of aerodynamic analysis,the fourth order Runge-Kutta method is used to calculate the external ballistic parameters of the corrected projectile,obtain the simulated trajectory,and preliminarily compare it with the actual trajectory.The results indicate that the simulation analysis of the duck rudder correction mechanism is consistent with the actual trajectory,and can predict the correction ability.
