上升段引力常数变化及其对弹道导弹运动的影响

对上升段引力常数的变化进行了系统的分析,建立了上升段引力常数变化的分析模型,给出了大气层引力及引力常数随高度的变化,并将结果应用到洲际导弹的弹道计算中.通过分析,上升段引力常数的变化对10 000 m射程导弹的影响约在米的量级,在一般计算中可不予考虑.

Gravitation Constant Variety in Ascend Phase and its Effect on Ballistic Missile

The graviation constant variety in ascend phase is analyzed systmically and an analysis model for the gravitation constant variety in ascend phase is establised.The variations of both atmospheric gravity and gravitation constant along with the height is presented,furthermore,the results are applied to the trajectory computation of ICBM.By analysis,a conclusion that the effect of the gravitation constant variety in ascend phase takes on the missiles with a range of 10 000 m is only in the magnitude of meter,thus can be ignored in the common computation.
