Descending prevention method for small missile ground launching

The invention relates to a descending prevention method for small missile ground launching. The main reasons causing descending in the small missile ground launching process comprise large missile low-head angular speed at the moment of deorbit and insufficient posture adjustment capability due to low initial speed at the moment of deorbit. By setting a deorbit mode, matching missile launcher and a missile sliding block, fixing a launching platform, planning a launching angle, presetting a control surface and adjusting full missile longitudinal mass center, the problems that the missile low-head angular speed is large at the moment of deorbit andand the posture adjusting capacity is insufficient due to lowinitial speed at the moment of deorbit can be solved, and the missile is prevented from descending after being launched. 本发明涉及一种小型导弹地面发射防掉高方法，小型导弹地面发射过程中，导致掉高的主要原因包括离轨瞬间导弹低头角速度大和离轨瞬间初始速度低姿态调整能力不足。通过离轨方式、导弹发射架和导弹滑块匹配、发射平台固定、发射角度、预置舵面、调节全弹纵向质心，可以改变离轨瞬间导弹低头角速度大和离轨瞬间初始速度低姿态调整能力不足的问题，防止导弹发射后掉高。
