摘　　要：为了消除推力偏心、气动偏心等影响,脉冲修正弹一般都低速旋转。但低旋时修正弹转速应避免共振,保证弹的飞行稳定性,而且转速的大小还会影响到脉冲修正的效率,文中从以上方面分析了脉冲修正弹转速设计时需要考虑的各种因素,给出了一些计算结果。For trajectory correction projectiles forced by impulse, it usually take low-rotation to vanish the aerodynamic offset and eccentric force. But while lowly rotating, projectile should avoid resonance to insure the flight stability. Considering the flight stability and correct efficiency of impulse engine, some factors were discussed in design of rotational speed.

关 键 词：脉冲修正 转速 共振 飞行稳定性
