The overall shape of the thrust propeller blade is a saber-shaped sweepback shape, the diameter D of the thrust propeller blade can be reduced to 2.6 m, the thrust propeller blade can be matched with an engine with the power grade of 900 kilowatt to work, and various parameters of the thrust propeller blade are matched with the power, the tension requirement and the installation size requirement of a thrust propeller supplied by a novel high-speed aircraft, so that the thrust propeller blade can be used for a high-speed aircraft. The thrust propeller blade is suitable for being installed on a novel high-speed airplane, and after the thrust propeller blade is installed on the novel high-speed airplane, aerodynamic loads can be optimally distributed on the propeller blade, so that the propeller noise is reduced, and the incoming flow speed of an airfoil within the area range is reduced.
本发明公开了一种推力螺旋桨桨叶,整体形状为马刀型后掠形状,且可将推力螺旋桨桨叶直径D减小为2.6m,则可以与900千瓦功率等级发动机配套工作,且发明的各项参数与新型高速飞机供给的推力桨功率、拉力需求以及安装尺寸要求匹配,因此,本发明的推力螺旋桨桨叶适合安装在新型高速飞机上,以将本申请安装在新型高速飞机上后,可以使气动载荷最优分布在螺旋桨的桨叶上,从而降低螺旋桨噪声,以及减小区域范围内翼型的来流速度。
