基于TSP方法的自然层流机翼转捩位置测量

为验证某层流机翼的设计，在荷兰DNW-HST风洞开展了高速风洞试验，采用TSP方法对机翼表面边界层转捩位置进行了测量。试验结果表明:TSP方法用于探测自然层流机翼表面转捩位置非常有效，显示结果中层流和湍流区域明显，转捩边界清晰易辨。同时发现，试验对机翼表面光洁度要求很高，试验结果对机翼表面污染非常敏感，高雷诺数下，受机翼前缘污染影响，试验效果不佳。

Transition measurement for the nature-laminar wing based on TSP technique

In order to verify the design results of a laminar flow wing, a high-speed wind tunnel test was carried out in the DNW-HST wind tunnel in the Netherlands, and the transition position of the boundary layer on the wing surface was measured by the TSP method in the test. The experimental results show that the TSP method is very effective in detecting the transition position of the natural laminar airfoil surface. At the same time, it is found that the test has high requirements on the surface finish of the wing, and the test results are very sensitive to the surface pollution of the wing.
