2.4m跨声速风洞大迎角试验技术研究

Research on the tests technology at high angles of attackin 2.4m transonic wind tunnel

介绍了2.4m跨声速风洞的大迎角试验机构、试验技术,以及大迎角标模(CT-1)和某四代机等两个模型的调试试验情况。试验结果与国内、外其他风洞的试验结果具有较好的一致性,试验精度相当。标志着2.4m跨声速风洞的大迎角试验机构和试验技术研究取得了初步成功。

The tests in 2.4m transonic wind tunnel on the high alpha setup and tests technology with two models,including the CT-1 model and an advanced fighter model, are introduced in this paper. The results have better consistency and the same precision with those of other wind tunnels at home and abroad, indicating that the high alpha setup and the research technology of 2.4m transonic wind tunnel are successful.
