Abstract:

Aiming at the existing constraints of layout design of miniature munition, a new layout optimization scheme is proposed. Based on the normal layout structure, a three-dimensional aerodynamic model of munition is established, and the aerodynamic hydrodynamics simulation of miniature munition is carried out, and the influence of wing size on static stability of munition is studied. To verify the feasibility of the design scheme, the aerodynamic simulation calculation is carried out, and the lift, drag and pitching moment parameters of miniature munition are obtained through simulated aerodynamic calculation under different flight conditions, and the lift-drag ratio and available overload are calculated. The simulation results show that the proposed aerodynamic layout scheme of miniature munition can meet the design requirements, and has good aerodynamic characteristics and flight stability, which can be a reference to the subsequent design.

Key words: miniature munition, normal layout, wing size, aerodynamic characteristic, flight stability
