高阻力发散马赫数机翼设计

Wing Design with High-Drag Divergence M-Number

针对高亚音速飞行器设计要求,在满足特定位置翼型厚度的前提下,对二维翼型及三维机翼进行优化设计,确保飞行器具有良好的高速巡航特性及较大的阻力发散马赫数。通过CFD数值计算对优化设计前后翼身组合体气动特性进行计算分析,结果表明,优化设计后机翼满足设计要求。

Considering the design requirement for the high subsonic flying vehicle, the optimization design on 2D and 3D wings has been accomplished under condition of satisfying the profile thickness requirement at specific location, purposing to ensure that the flying vehicle is possessed with excellent high-speed cruising characteristics and greater drag divergence M-number. The calculation analysis has been conducted respectively on aerodynamic characteristics of wing-fuselage blended body before and after the optimization design via CFD numeric calculation,and the result shows that the wing after optimization design can satisfy the design requirement.
