俯冲击顶弹道落角研究

Impact Angle of Upper Attack Trajectory

采用俯冲击顶弹道时,为保证对目标的毁伤效果,要求导弹命中目标时具有较大的落角。为增大落角,分别研究了射程和弹道高度、转比点、比例导引系数以及可用法向过载等因素对落角的影响,并进一步提出了提高落角的措施。仿真和引证表明,通过采取调高发射角、加入推力矢量控制以及改进末制导律等措施可有效提高导弹落角。

A larger impact angle is needed to guarantee the damage effect of the missile when upper attack trajectory is adopted. To increase the impact angle and damage effect of upper attack trajectory, the influences on impact angle are analyzed from the aspects of range and height of trajectory, turning over point and coefficient of proportional navigation, and available normal overload respectively. Moreover, measures to increase the impact angle are proposed such as adjusting launch angle, adopting thrust vector control and improving terminal guidance law. Simulation and citation references show that the irapact angle can be increased effectively with these measures
