基于旋转稳定和尾翼稳定的弹丸飞行稳定性研究

在弹丸飞行稳定性准则的基础上,阐述了弹丸飞行稳定性的条件,并着重讨论陀螺稳定因子、动态稳定因子以及瞬间扰动对弹丸稳定性的影响.通过对摆动理论和旋转理论的分析研究,给出旋转弹和尾翼弹丸稳定性条件.研究表明：要同时满足陀螺稳定性和追随稳定性两个要求比较困难,有时甚至是矛盾的,这时需要采用合理的膛线缠度来保证.

Analysis of Projectile Flight Stability based on Empennage and Rotation Stability

Based on the flight stability criterion, the stability condition of the flight projectile is elaborated, gyro stabilized factor, dynamic stability factor and instantaneous disturbance on the stability of projectile. and focus on Through the analysis and study of the rotation theory and the swing theory, the methods of steady flight of projectile are given. Study shows that while meeting the gyro stability and following stability contradictory. Then a reasonable rifling degree has to be adopted to of two requirements is very difficult and sometimes insure stability.
