摘要
针对末修弹脉冲修正特点,研究了脉冲横流对末修弹道特性的影响规律。建立了末修弹横向喷流工作时的气动弹道模型,计算了脉冲力的作用位置对末修弹轨迹、速度和攻角特性的影响关系;在获得横向喷流工作对末修弹气动特性影响规律的基础上,对比分析了脉冲横流产生的干扰气动力、干扰气动力矩及这两种因素的综合对末修弹道参数的影响关系。结果表明,干扰气动力对末修弹道特性的影响不大,干扰气动力矩对末修弹道特性的影响明显,而影响程度与脉冲作用位置有关。
According to the characteristics of terminal correction projectile with impulse crossflow,the law of the impulse cross-flow influencing the ballistic performance was researched.The ballistic model while cross-flow working was built,and the relationship of the placement of impulse force influencing characteristics of the trajectory,velocity and angle of attack was studied.Based on acquiring aerodynamic characteristics of the projectile influenced by the crossflow,the laws of the ballistic parameters influenced by the additional aerodynamic force,additional aerodynamic moment and their integration caused by the impulse cross-flow were comparatively analyzed.The result indicates that the additional aerodynamic force caused by impulse cross-flow has few influence on ballistic characteristics,while the additional aerodynamic moment has obvious influence;the influence degree has relation with acting position of impulse cross-flow.
