Three-component forces were measured using two models, one small and the other large, and the data were compared with the estimated uncertainties as well as those of other wind tunnels. The repeatability of forebody lift coefficient (C(sub LF)) and pitching moment coefficient (C(sub m)) between the tests were good while repeatability of forebody drag (C(sub DF)) without roughness was poor because of the reduced turbulence level of the wind tunnel flow leading to the laminarization on the model surface. With low drag roughness applied, the repeatability was improved. C(sub LF) and C(sub m) agreed well with those of other wind tunnels while C(sub DF) was lower due to the larger laminar region on the model surface. In conclusion, the performance of the wind tunnel was verified with standard data established., 資料番号: AA0063877000, レポート番号: JAXA-RR-06-046}, title = {超音速風洞におけるAGARD-B標準模型3分力試験}, year = {2007} }
