小直径炸弹复合制导律设计与仿真

Hybrid Guidance Law Design and Simulation for Small Diameter Bomb

摘要:

采用钻石背翼的小直径炸弹,具有升阻比高、航向机动能力差等气动特性。在侧滑角和滚转角均受到约束的条件下,滑翔段采用STT+BTT并联复合制导方式,攻击段采用STT制导方式,能够有效地满足大扇面角发射时对侧向过载的需求。仿真结果表明,这种制导策略能够有效地满足制导律的设计要求,提高小直径炸弹大扇面角发射时的侧向机动能力。

Abstract:

The small diameter bomb with the diamond back wings has aerodynamic characteristics of high lift-drag ratio and low lateral maneuver ability. Subject to the constraint of sideslip angle and roll angle, hybrid STT and BTT maneuver was employed in the gliding phase and STT maneuver is only employed in the diving phase to satisfy the required overload of sector launch. The simulation results showed that the hybrid guidance law could meet the requirements, and enhance the lateral maneuver ability of large sector launch.
