Several key technologies and beneficial engineering design experiences in the aerodynamic design of stealth carrier-based aircraft are introduced in this paper. Based on three aspects including the design of enhancing lift at the taking-off and landing status, refined drag reduction for supersonic flow and the balanced design of load reductions, the concepts of extreme narrow-range aerodynamic design under multi-specialty constraints such as performance, stability, weight and stealth are stated. Relative research shows that the requirements of the lift at the taking-off and landing status can be satisfied by the simple flap design with the optimization of three-dimensional bending of wings. The drug of the aircraft can be reduced by optimizing the cockpit and the compressible/expansion waves at the fuselage and the directions of overflow suction. Moreover, the load reduction of the horizontal tail can be gained by the reverse bending design of the lower fuselage and the barrage hatch.
