弹道修正弹在脉冲力矩作用下的飞行稳定性条件

Flight Stability Condition for a Projectile of Corrected Trajectory with Impulse Moments

弹道修正是近年来为提高弹药设计精度而出现的一种新技术。该文对弹道修正技术中常采用的脉冲力矩修正作用 ,对弹丸飞行稳定性状况的影响等进行了讨论 ,给出了脉冲力矩作用下飞行稳定性条件。这对目前开展的修正弹道技术研究 ,特别是对弹道修正设计方案的选取 ,有一定的参考意义。

The trajectory correction is a new technology to improve the design precision of projectiles. The impulse moments are often used to adjust the trajectory for some precision munitions and they will affect the flight stability for these munitions. The paper analyses this kind of influence and a condition of flight stability to be satisfied has been set up when these impulse moments act on the moments. It is useful for considering these precision munitions.
