The invention provides a special airfoil profile matching a high-universality large-load small unmanned aerial vehicle. The maximum relative thickness of the airfoil profile is 12.19% C, and the chordwise position corresponding to the maximum relative thickness is 27.1% C; the maximum camber is 5.3% C, the chordwise position of the maximum camber is 48.3% C, and the C is the chord length. The design Reynolds number of the airfoil profile is 3*10<5>-2*10<6>. The airfoil profile has the aerodynamic characteristics of high lift force and high lift-drag ratio (the maximum lift-drag ratio being greater than 100) and good engineering implementability in a design state, and can be applied to the design of a high-universality large-load small unmanned aerial vehicle, and the matched unmanned aerial vehicle has a relatively high lift-drag ratio under multiple speed working conditions.

    本发明提供一种匹配高通用性大装载小型无人飞行器的专有翼型。翼型最大相对厚度为12.19%C,最大相对厚度对应弦向位置为27.1%C;最大弯度为5.3%C,最大弯度所在弦向位置为48.3%C,其中C为弦长。本发明翼型设计雷诺数为3×10~2×10。该翼型在设计状态下具有高升力高升阻比的气动特性(最大升阻比大于100)和良好的工程可实施性,可应用于高通用性大装载小型无人飞行器设计,匹配后的无人飞行器全机在多个速度工况下具有较大升阻比。
