摘　　要：采用镜像两步法在FL 8风洞中进行了俯仰振荡动导数支架干扰修正实验,实验结果表明:在强迫振荡动导数实验中,支架干扰对动导数实验数据有明显的影响。通过对实验数据进行支架干扰修正,可以进一步提高实验结果的准确性。An experiment to account for support interference in the oscillatory dynamic stability derivative wind tunnel tests has been conducted in the FL8 low speed wind tunnel of the CARIA. The result shows that the effect of the support couldn't be ignored in the wind tunnel oscillatory tests.The accuracy of the test results after support interference correction is raised.
