摘　　要：针对采用有限、短时脉冲推力弹道修正方案的某口径对空低旋尾翼弹,为了研究脉冲推力强干扰对弹丸姿态和弹道修正效果的影响,理论推导了脉冲推力强干扰下弹丸角运动变化和修正落点偏差公式,分析了单次脉冲修正力的修正特性,结合仿真研究了单次和连续多次脉冲推力修正时弹丸自转角速度、修正力作用时间和力的大小、修正相位角、修正起始时刻以及安装偏心距对修正效果的影响,为设计修正器参数提供理论数值参考。In order to figure out the influence of strong pulse thrust interference on projectile attitude and trajectory correction,this paper theoretically derives the formulas of projectile angular motion change and corrected drop point deviation under strong impulse thrust interference for a certain fin-stabilized projectile at a low spin speed based on limited and short-time pulse thrust trajectory correction scheme.The correction characteristics of single pulse correction force is analyzed.Combined with the simulation,the effects of single and continuous pulse thrust correction on the projectile rotation angular velocity,the duration and strength of the correction force,the correction phase angle,the correction start time and the installation axial eccentricity on the correction effect are analyzed.The results of the analysis provide theoretical and numerical reference for the design of parameters of the correction mechanism.
