【摘要】 利用脉冲发动机对火箭弹弹道进行修正时,采用一般的坐标转换方法计算脉冲发动机产生的推力矢量与误差矢量对应关系,并由此决定脉冲发动机是否点火.存在理论上的误差.射角越大,误差越大,该问题具有一般性,文中对其作了分析并给出一种解决方法。更多还原

【Abstract】 If the angle of fire is large,using pulse jets to correct the rocket trajectory,the error in theory in the relation between thrust vector produced by pulse jets and the error vector corrected will arise,which is established by the general coordinate transform in order to decide which pulse jet will be fired.The larger the angle of fire is,the larger the error is.The question is universal.It is analyzed and one solution is provided in the paper.更多还原
