Abstract: In order to shorten the response time of over-the-shoulder launch of close-range combat missiles and realize the rapid strike of air-to-air missiles on rear targets in close-range combat, a method for rapid backward launch of air-to-air missiles is proposed, which utilizes the static instability of missiles at large/super-large angles of attack, and assists with jet direct force control and terminal active rudder deflection control. In order to study the influence of preset rudder deflection, jet direct force and terminal active rudder deflection control strategy in the new launch method proposed by the institute, a high-precision computational fluid dynamics/flight dynamics numerical simulation method of coupled active rudder deflection control strategy based on dynamic nested grids is developed. The numerical simulation results show that the proposed method can complete the rapid redirection of the missile within 1.53s and keep the attitude stable and controllable in the final stage of flip. The new method can shorten the redirection time of over-the-shoulder launch to about 1/10 of the traditional method.
