| 摘 要： | 介绍了风洞试验中常采用的前最转捩和后最转捩的特点以及使用中的限制，通过某超临界机翼的试验与数值计算压力分布的比较，重点分析了不同位最的固定转捩对机翼压力分布的影响，并对机翼测压试验中所出现的问题做了分析。通过对高雷诺数风洞试验结果的研究，讨论了低雷诺数风洞中利用自由转捩技术模拟高雷诺数情况下机翼压力分布问题。

| Abstract: | This paper introduces the characteristics and limitation of the fore-fixation and aft-fixation transition techniques in wind tunnel test for supercritical wing and also presents the related problems which existed in experiment, analyzes the effect of different transition position on the pressure distribution of supercritical wing by comparing the results of computation with that of wind tunnel test. According to the result of high Reynolds test, This paper also proposes how to achieve the pressure distribution of supercritical wing in flight in low Reynolds wind tunnel test by utilizing free transition technique. |
