高速风洞超大迎角试验技术初步研究

Preliminary research on super-high angle of attack test techniques in a high speed wind tunnel

大迎角风洞试验技术是先进高机动飞行器研制必需的关键技术。气动中心发展的高速风洞超大迎角试验技术 ,包括大迎角机构、模型、天平等。 1 .2m风洞超大迎角试验结果与 2 .4m量级的大风洞试验数据具有较好的一致性 ,试验精度基本达到了××标准对小迎角试验精度的要求 ,表明 1 .2m风洞超大迎角试验技术研究获得了成功。

High angle of attack wind tunnel test techniques is necessary for development of high-maneuverability flight vehicles. This paper briefly introduces the high angle of attack test techniques developed by High Speed Institute of CARDC,which include the high-angle of attack support rig, calibration models, balances and test results. High angle of attack test results of 1.2m wind tunnel agree well with those of 2.4m wind tunnel. The test precision proves that the high angle of attack techniques are successful.
