摘要
通过对多点优化策略方法的研究,并将该方法应用在机翼的气动设计中。给出初始机翼外形,利用型函数生成几何扰动量叠加方法对机翼的各个剖面翼型进行修改,然后,调用GA-PSO进行优化计算,迭代结束后得到在设计工况点更为优异的几何外形。结果表明:最终得到的优化机翼与初始机翼相比,有效地提高了巡航效率,并且,也能较好满足阻力发散马赫数的要求,具有更好的综合气动性能。
A new method was applied to the wing aerodynamic optimization design based on the research of optimization strategy. The Hicks Henne function for generating geometric disturbance was used to modify the sections of the initial wing. A better shape was given in cruise points after multiple iterations using GA-PSO method. The design results indicate the final wing compared with the initial wing,effectively im-proves the cruise efficiency with better aerodynamic performance and can also better meet the require-ments of the drag divergence Mach number.
