The invention provides a supersonic large-maneuvering stealth target aerodynamic layout. The supersonic large-maneuvering stealth target aerodynamic layout comprises a head cover, a fuselage middle section, a fuselage tail section, wings, ailerons and a camber full-maneuvering V tail. The head cover, the fuselage middle section and the fuselage tail section are sequentially connected, the head cover adopts an oval section, and edges are arranged on the two sides of the head cover. The fuselage middle section adopts an elliptical uniform-section fuselage, and edges are arranged on the two sides of the fuselage; the wings adopt sweepback trapezoidal wings; the aileron is arranged at the tail edge of the rear end of the wing; the tail part of the tail section of the fuselage is provided with an outwards-inclined full-motion V tail for manipulating and controlling the target, and the outwards-inclined full-motion V tail adopts an inclined double-vertical-tail layout; the target adopts bilateral air intake, and the wings, the fuselage middle section and the fuselage tail section adopt a wing body and lifting body fused aerodynamic layout. The aerodynamic layout target is smooth in layout and excellent in aerodynamic characteristic. According to the method, the actual target supply process is combined, the subsonic speed cruising characteristic, the supersonic speed target supply section cruising characteristic and the large maneuvering flight characteristic of the target are considered, the good stealth performance is achieved, and the typical flight characteristic and the target characteristic of the fifth-generation aircraft can be simulated.
