摘要
介绍了研究太阳能无人机气动特性时的控制方程与湍流模型。为设计出具有较高气动性能的太阳能无人机,应用计算机软件对具有较高升阻比的翼型进行气动特性分析,进而选取合适的翼型。与此同时,在相同机翼面积和机翼展长的情况下,对新型串列翼布局和常规单翼布局太阳能无人机进行气动特性分析,确认新型串列翼布局具有更高的气动性能。
The governing equations and turbulence models for studying the aerodynamic characteristics of solar UAV were introduced.In order to design a solar UAV with high aeroperformance,computer software was used to analyze the aerodynamic characteristics of the airfoil with higher lift-drag ratio,and then selected the appropriate airfoil.At the same time,the aerodynamic characteristics of the solar UAV with same wing area and wing length but in new tandem wing layout and in conventional single-wing layout were analyzed.It is confirmed that the new tandem wing layout has higher aerodynamic performance.
