摘要

摘要: 为满足共轴刚性对转旋翼气动特性及流动机理研究的风洞试验需要，在中国空气动力研究与发展中心Φ3.2 m风洞开展了共轴刚性对转旋翼试验台（以下简称共轴旋翼试验台）研制。该试验台可开展Φ2 m量级双旋翼模型的桨尖马赫数相似试验，是研究双旋翼构型高速直升机气动特性的重要试验设备。采用上、下旋翼模型独立支撑、单一电机驱动，实现了同步反向旋转、同步改变旋翼轴倾角、旋翼总距、旋翼周期变距等远程实时控制功能；通过设计计算-测试-调节的迭代，解决了试验台台体的动力学特性匹配问题；合理选择设计参数，解决了传动系统稳定性问题；利用该试验台获得的某旋翼模型风洞试验结果，拉力系数的重复性精度优于0.58%，扭矩系数的重复性精度优于0.11%。

Abstract: To meet the needs of the wind tunnel experiment, China aerodynamics research and development center successfully developed the Φ3.2 m coaxial rigid rotor stand for wind tunnel experiments. The test of coaxial rigid rotor models with a diameter of 2 m can be carried out on this test stand. The upper and lower rotors are supported separately and rotate conversely. The coaxial rotor test stand realizes remote and synchronous real-time control over the rotor shaft angle, collective and cyclic pitch, and so on. From the iteration cycle of simulation-test-adjustment, dynamic issues of the test stand are addressed. The design parameters of the transmission system are selected carefully to guarantee the stability. The wind tunnel test results of the model coaxial rigid rotor show that the repeatability precision of thrust can be better than 0.58%, and the repeatability precision of torque can be better than 0.11%.
