摘　　要：本文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 transonic area rule, and the aerodynamic force of the blended wing - body before and after optimization of the shape is simulated by solving the 3 - D, Euler equations. The result indicated that in the Mach number scope 0.8 ≤M≤2.0, using the transonic speed area rule to carry on the optimized design can achieves the lift augmentation and the drag decrease.
