合理选择模型的支撑形式和解决支架干扰问题是准确获取气动力数据的关键因素。为了寻找一种合适的运输类飞机在高速风洞试验中的支撑形式,首先通过计算分析和试验验证,给出了运输类飞机高速风洞试验中30°尾支撑支架干扰问题存在的原因,然后根据0°、5°、15°以及30°不同尾支撑形式的计算分析和专项试验论证结果,提出并验证了小角度尾支撑是现阶段运输类飞机高速风洞试验中最合理、最有效的支撑形式。
閤理選擇模型的支撐形式和解決支架榦擾問題是準確穫取氣動力數據的關鍵因素。為瞭尋找一種閤適的運輸類飛機在高速風洞試驗中的支撐形式,首先通過計算分析和試驗驗證,給齣瞭運輸類飛機高速風洞試驗中30°尾支撐支架榦擾問題存在的原因,然後根據0°、5°、15°以及30°不同尾支撐形式的計算分析和專項試驗論證結果,提齣併驗證瞭小角度尾支撐是現階段運輸類飛機高速風洞試驗中最閤理、最有效的支撐形式。

Choosing right model support form and resolving sting interference problem are key factors while obtaining exact aerodynamic data.It is necessary to find out an appropriate support form for transport aircraft in high-speed wind tunnel test.Through calculation analysis and test,the reason that sting interference problem exists in 30° aft-body support form is explained first.Then according to the results of calculation analysis and special test of 0°、5°、15° and 30° different aft-body support form,the conclusion is obtained and validated that small angle aft-body support form is the most reasonable and the most effective support form for transport aircraft in high speed wind tunnel test at present.
