气动参数设计对分离式旋转弹级间作用力的影响

The Analysis of Aerodynamic Parameters Affecting the Forces Between Two Stages of Stage-separating Spinning Missile

通过定量分析多个气动参数对级间作用力的影响程度,可知合理设计两级弹体气动外形可以有效减小弹体的级间作用力。同时必须根据弹体气动参数和设计过载情况来校验弹体级间部分强度,以防结构破坏。

The effects on the forces between two stages of some aerodynamic parameters were analyzed, and through reasonable designation of the aerodynamic figure of the missile, the forces between two stages could be reduced effectively. And in order to avoid structure-breaking, the intensity of the two-stage structure should be verified based on the characteristics of aerodynamic parameters and over-loading condition.
