摘　　要：桨后定子是影响涵道螺旋桨推进效率、转矩抵消和桨后滑流整流效应的重要部件之一,为研究桨后定子对气动推进增效、消旋及桨后滑流整流效应的桨后定子构型气动综合设计和参数影响机理,采用CFD数值模拟和风洞试验验证相结合的研究手段,重点开展了考虑涵道、桨叶、定子与发动机短舱等多部件复杂干扰下的涵道桨桨后定子构型典型气动布局形式和参数影响机理研究,从定子叶片径向站位型面外形弯度大小、桨叶扭转角和弦长分布等方面,阐释了4种典型定子构型布局形式对推进效率提升、转矩抵消、滑流整流效应等的影响关系。研究表明:良好的定子构型能够使涵道桨推力提升1%~3%;同时,使涵道桨装置的总转矩值抵消约94.5%。The stator is one of the important components which affect the propulsion efficiency,torque reduction and propeller slipstream rectification,In order to study the mechanism of aerodynamic comprehensive design and parameter influence of stator configuration on aerodynamic propulsion efficiency,de-rotation and paddle slipstream rectification effect of stator.this paper adopts a combination of CFD simulation and wind tunnel test,under the complex interferences of the ducted,the blade,the stator and the engine nacelle,the typical aerodynamic configurations and the parameter influence mechanism on the configuration of the stator were studied;from the aspects of the stator airfoil,the torsion angle and the chord length distribution of stator,the influences of four typical stator configurations on the propulsion efficiency,torque reduction and the influence of slipstream rectification were analyzed.The results showed that a good stator configuration can increase the propulsion efficiency of the ducted propeller by 1%—3%,and offset the total torque of the ducted propeller by about 94.5%.
