利用CRM模型,通过合理的静气动弹性计算方法,并结合ETW风洞试验数据,分别研究了静气动弹性和雷诺数对于风洞试验压力分布的影响。最后又同时结合静气动弹性效应和变雷诺数效应,研究了在它们的共同影响下压力分布的变化趋势。同时可以看到,对于大型客机这类风洞模型尺寸缩比较大,并且展弦比和后掠角都较大的跨音速飞行器,其在风洞试验时要充分考虑到静气动弹性对于压力分布的影响,并进行相应的修正,才能得到合理可信的结果。
Based on the CRM model and the reasonable calculation method of dynamic and dynamic aerodynamics, combined with ETW wind tunnel test data, the effects of static-dynamic elasticity and Reynolds number on the pressure distribution in the wind tunnel were studied. At the same time, combined with the static-dynamic elastic effect and the Reynolds number effect, the changing trend of pressure distribution under their common influence is studied. At the same time, it can be seen that for wind tunnel tests of large-scale passenger aircraft, the size of such wind tunnel models is quite large and the transonic aircraft with large aspect ratio and sweep angle have sufficient consideration for the static-dynamic elasticity. For the pressure distribution Influence, and make the appropriate amendments in order to get a reasonable and credible results.
