对涵道螺旋桨在悬停和轴向飞行条件下的性能特性和速度场进行了实验研究。管道具有 NACA 翼型轮廓，螺旋桨位于管道最窄的内部部分，直径为 0.42 米。测试对称和负弧形轮廓。通过在不同流动条件下的测量来研究管道几何形状的影响。测量螺旋桨上游和下游的速度场、作用在推力系统各部件上的轴向力、转子转速和扭矩。比较了裸螺旋桨和涵道螺旋桨获得的实验结果。
Performance characteristics and velocity field of a ducted propeller in hover and axial flight conditions are investigated experimentally. The duct has a NACA airfoil profile and the propeller is located at the narrowest inner section of the duct which has 0.42 meter diameter. Symmetric and negative cambered profiles are tested. Effect of duct geometry is studied by means of measurements at various flow conditions. Velocity field upstream and downstream of the propeller, axial force acting on each component of the thrust system, rotor speed and torque are measured. Experimental results obtained for bare and ducted propellers are compared.
