Research on the Safety of Rearward Launch Separation of Semi-Recessed Wing-Mounted Missiles

In this study, a backward launch method for missiles placed on semi-recessed wings is proposed to reduce the interference effects during the missile-aircraft separation process. The feasibility of this launch strategy and the safety of missile-aircraft separation were verified using an unsteady computational fluid dynamics (CFD) modeling method. Using six-DOF rigid body dynamics equations and unstructured dynamic mesh technology, a numerical simulation of the rearward launch process of missiles mounted on semi-recessed wings was carried out. The separation flow field and missile trajectory parameters were obtained at different times. The results show that during the first separation phase, the missile has low aerodynamic interference from the carrier aircraft, its attitude changes minimally, and the missile may separate from the carrier aircraft rapidly, safely, and stably.
