根据传统机翼气动外形设计的方案,结合CAD与CFD软件,本文提出了一套机翼气动外形设计流程,包括翼型选择、机翼平面参数确定、建立三维机翼外形模型、流场网格划分和典型飞行条件下的气动计算等多个部分。依据该流程,完成了一个满足设计指标的无人机大展弦比机翼外形的设计,充分说明了该机翼气动外形设计流程的技术可行性。
According to the scheme of aerodynamic profile design of traditional wing and CAD and CFD software, this paper presents a set of wing aerodynamic profile design process, including the choice of airfoil, the determination of wing plane parameters, the establishment of three-dimensional wing profile model, Division and aerodynamic calculation under the typical flight conditions and other parts. According to this process, a design of large aspect ratio airfoil that meets the design requirements of the UAV is completed, which fully demonstrates the technical feasibility of the airfoil shape design flow of the airfoil.
