先进无人机翼型气动设计方法研究

探讨了传统的优化设计方法和反设计方法在翼型设计中的应用,针对遗传算法存在计算量大、精度低的不足,以及反设计方法难以提供合理目标压力分布的难题,为提高已有气动设计方法的工程实用性,将基于遗传算法的优化方法与反设计方法结合起来进行了翼形的气动外形设计.结果表明,所采用的翼型设计方法是正确、有效的.

Aerodynamic Design Research of Advanced UAV Airfoil

Past researchers either use optimization or inverse design method,both have advantages and disadvantages.The genetic algorithm method is converging slowly and difficultly,while it is difficulty to provide the desired pressure distribution with an inverse design method.In order to enhance the efficiency and the feasibility of the airfoil design,the optimization design method combined with the inverse design method was developed.Numerical results of a design example show that the airfoil design method is effe...
