摘　　要：用跨音速面积律对某翼身融合体进行修形设计,并通过三维欧拉方程对修形前、后的融合体气动力进行了数值模拟。模拟结果的对比表明:在计算的马赫数范围内(0.8≤M≤2.0),采用跨音速面积律进行优化设计能达到增升减阻的效果。The blended wing -body is optimized by the uansonic area rule in design, and the aerodynamic force of the blended wing - body before and after the optimization is simulated by solving the 3 - D, Euler equation. The comparison result after the simulation indicates： Within the Mach number scope of 0. 8≤M≤2.0, the optimized design by using the transonic speed area rule can achieves the effect of the lift augmentation and drag reduction.
