民机低速风洞测力试验技术研究

民机低速风洞测力试验技术是中国航空工业空气动力研究院低速所新研制的一项试验技术,为了达到国际先进测量水平,该项技术先后成功研制了专用的应变天平,改进了模型支撑和稳风速控制系统,用CRJ民机模型进行了风洞试验验证。试验结果表明:FL 8风洞的测量精度已经达到了国际先进水平。

Investigation of civil airplane force measurement in low speed wind tunnel

The low speed institute of CARIA has developed the new technology through which the low speed wind tunnel force measurement test for civil airplanes are carried out. In order to reach the international standard, we have sequentially designated the special strain ganged balance, and improved the model support and the steady wind speed's controlled system. At last, we prove it validity by the test of CRJ which is the civil airplane's model. The test results demonstrate that measurement precision of the FL-8 wind tunnel have reached the international advanced level.
