细长杆异型截面弹芯的运动方程组

The Movement Equations of a Non-Circular Cross-Sectional Slender Projectile

异型截面弹芯由于其弹体长径比大和飞行速度高,在空中的柔性变形已不可忽略。为此,文中建立了异型截面弹芯柔性变形时弹轴运动的微分方程,以便分析柔性变形对杆式弹飞行性能的影响,特别是对异型截面弹芯的运动稳定性的影响。

The distortion of a slender projectile cannot be ignored when it flights at the supersonic velocity in the air. The paper establishes the movement difference equations of the projectile with distortion, so that the effect of the distortion can be acquired on the flight performance, especially on the movement stability of the projectile.
