为提高微小型无人垂直起降飞行器的载重能力,针对其升力螺旋桨的悬停性能进行了系统性的参数对比实验.通过对实验数据进行分析对比和静推力状态螺旋桨片条理论计算,得出了各种几何参数对几何定距螺旋桨悬停性能影响的一系列结论.给出了此类螺旋桨的性能实验数据,结果表明较大的直径可显著改善悬停性能,同时存在最佳的中等偏低几何螺距、实度和平面形状,但后两个因素对此类螺旋桨的悬停性能影响较小.
In order to improve the load carrying capacity of the miniature unmanned vertical takeoff and landing aircraft, a systematic parameter comparison experiment was carried out for the hovering performance of the lift propeller.By analyzing the experimental data and calculating the propeller blade theory under the static thrust condition, A series of conclusions about the influence of geometrical parameters on the hovering performance of geometric pitch propellers are given.Experimental data on the performance of such propellers are given.The results show that larger diameters can significantly improve the hovering performance and meanwhile the best mid- Low geometric pitch, solidity and planar shape, but the latter two factors have little impact on the hovering performance of such propellers.
