摘要

摘要: 对大型水陆两栖飞机翼型进行了数值优化设计研究,通过以翼型设计升力系数下的阻力系数最小化为设计目标和以翼型低头力矩、最大升力系数、失速后升力系数下降率作为约束条件的大型水陆两栖飞机翼型优化设计,在满足翼型相对厚度、最大厚度位置、最大弯度、最大弯度位置符合相应设计范围的情况下,得到了综合性能较基本翼型提高的新翼型.该设计方法适用于大型水陆两栖飞机的翼型设计,是一种符合工程应用实际的数值优化设计方法.

Abstract: The research discussed focused upon the optimal airfoil shape design of a heavy amphibious aircraft.A new airfoil with better general performance was attained through the optimal airfoil design,of which the objective was to reduce the drag coefficient on a given airfoil with constant lift coefficient.Restricted the pitch moment,the maximum lift,and the lift drop rate of stalling angle.Made the relative thick,the maximum camber,and the relative position of the maximum thick according with the design request.This design method is fit for the airfoil design on a heavy amphibious aircraft,and is a better optimal airfoil shape design which is suit for the engineering application.
