倾转旋翼机旋翼/机翼气动干扰的试验研究

Experimental Study on Rotor/Wing Aerodynamic Interaction for Tilt-rotor Aircraft

在模型旋翼台和风洞中,针对倾转旋翼机旋翼/机翼的两个主要干扰状态(悬停和低速前飞)进行了试验,分别测量了悬停状态不同机翼安装角和旋翼总距角、前飞状态不同机翼安装角和吹风速度等试验条件下的倾转旋翼拉力、扭矩以及机翼上下表面压力分布,并对试验结果进行了分析,得出了一些有意义的结论,为进一步研究倾转旋翼机旋翼/机翼气动干扰的特性问题做了些探索性的工作。

The two main states(hover and low-speed forward flight)of the interaction between rotor and wing are tested on the model rotor test rig and wind tunnel.The rotor thrust and torque as well as the wing surface pressure are measured both in hover with different pitch angle of wing and different collective angle and in forward flight with different pitch angle of wing and different wind speed.Then,the experimental results are analyzed,as a result,some meaningful conclusions are obtained,which make some exploratory work for further study on the aerodynamic interaction between rotor and wing for tilt-rotor aircraft.
