二元自适应壁风洞实验技术研究

THE RESEARCH OF TESTING TECHNIQUE ON 2-D ADAPTlVE FLEXIBLE WALL WIND TUNNEL

介绍了在柔壁自适应壁风洞中，进行大堵塞比翼型低、跨音速实验消除洞壁干扰的研究，叙述了西北工业大学低、跨音速柔壁自适应壁风洞实验的迭代方案和高亚音速一步调整方案，以及所进行的实验和计算验证。结果表明，本文提出的洞壁调整方案可以有效地消除二维柔壁自适应风洞中大堵塞比翼型实验的洞壁干扰。

It has been reported that two-dimensional self-streamlining flexible walled testsection eliminates the top and bottom wall interfereiice effects on large blockage aerofoiltesting.The iterative stratd.gies of subsonic flow test and transonic flow test and one stepmethod for high subsonic test was discribed.The experimentaI tests have been performed toverify the methods. The results show that theeffects of wall interference can be eliminatedby the methods effectively on iarge blockage aerofoil in twodimensional adaptive walledwind tunnel.
