【摘要】 为研究近程反坦克火箭弹采用脉冲发动机进行姿态稳定控制的效果,文中提出脉冲点火算法和脉冲发动机的等效合力模型,通过弹道仿真分别研究了初始扰动、推力偏心、常值风等主要干扰因素作用下姿态稳定系统的控制效果。研究结果表明,姿态稳定控制对初始扰动、推力偏心等干扰因素造成的弹道偏差能进行有效的控制,但对常值风干扰造成的弹道偏差无修正能力。因此,可以采用姿态隐定方式提高近程反坦克火箭弹的射击精度,但发射时必须提供气象条件保障。更多还原

【Abstract】 To study the attitude stabilization control effect on short-range antitank rockets using pulse jets.in this paper the pulse ignition arithmetic and the equivalent resultant force model of pulse jets are brought forward,and ballistic sim- ulation models are set up respectively under primary disturbance factors such as constant winds,initial disturbances. off-center thrust and so on.Results show that the attitude stabilization control is effective for trajectory errors caused by initial disturbances,off-center thrust,while it is ineffective for ones caused by constant winds.Therefore,the preci- sion of short-range antitank rockets can be improved by the attitude stabilization project on condition that the weather data is provided before shooting.更多还原
