激光制导炸弹的姿态控制引入时机研究

The Attitude Control Time Investigation of Laser-guided Bomb

文中以激光制导炸弹为研究背景,结合导弹稳定控制方法,利用机载武器分离安全理论,提出了一种导弹姿态控制引入时机分析方法。该方法在机弹分离的适当时机引入对导弹姿态的控制,可使导弹舵面转动实现对弹体姿态变化的抑制,保证了导弹离开载机过程中的姿态稳定。通过和无控条件下机弹分离后弹体姿态变化的对比,验证了适当时机引入姿态控制可提高导弹投放时的安全性。

Regarding laser-guided bomb, the occasion of attitude control after aircraft-missile separation was analyzed and deduced by using separation safety theory of airborne weapon and the method of steady control in this paper. This method of attitude control in felicitous time-point can restrain attitude change of bomb by executing rudder deflection, so it guarantees that the attitude of missile during separation from aircraft is always effectively steady. The digital simulation was compared with the attitude curves of missile without control. The simulation results prove that the occasion of attitude control has been introduced could greatly improve security of missile’ s separation from aircraft.
