| 摘 要： | 提出了一种高效率螺旋桨设计方法,该方法根据给定的飞行速度、螺旋桨转速、拉力、螺旋桨直径、桨叶数、翼型,能够计算出最大效率螺旋桨的几何特性,包括:桨叶的弦长分布、桨距角分布、效率、拉力系数、扭矩系数、功率系数.分别按爬升状态和巡航状态的工作参数设计了某型飞机的螺旋桨,得到了桨距角和弦长沿径向的分布.对螺旋桨的缩比模型(直径为0.84m)进行了风洞试验,风洞试验结果表明:螺旋桨在巡航状态的效率是83.02%,爬升状态的效率是79.13%.

| Abstract: | A design method for high efficiency propeller was presented. This method could calculate the geometric characteristics of maximum efficiency propeller, including the chord distribution, pitch-angle distribution, efficiency, thrust coefficients, torque coefficients and power coefficients based on the given flight velocity, rotating speed of propeller, thrust, diameter, blade number and airfoil. The propeller of an aircraft was designed using the parameters under climbing and cruise conditions, respectively. The chord distribution and pitch-angle distribution were obtained. Wind tunnel test of scaled model of propeller (diameter 0.84m) was carried out. The test results show that cruising efficiency of propeller is 83.02%, and climbing efficiency is 79.13%. |
