test facility which has the potential of realizing a higher Reynolds number.In order to obtain the characteristics of the flow in the Ludwieg tube and the performance of wing airfoils at a high Reynolds number at transonic regime,the transonic Ludwieg tube was constructed.The main dimensions are a two-dimensional transonic test section of 120mm×360mm,Mach number range of 0.45 to 1.1,maximum internal pressure of 1080 kPa and a duration time of about 0.1 second.At first,flow characteristics such as the steadiness of the stagnation pressure and Mach number,the duration time of a steady state and so on were obtained experimentally.The timewise change of the stagnation pressure was in the order of 4 per cent.At the region of M＞0.85,steadiness of the Mach number was gradually spoiled as the Mach number increased.Secondly,pressure distribution of the upper surfaces of the two airfoil models were mainly measured.Wing profiles of those models were derived from the exact solutions of the trnic potential flow equation of the hodograph method at NAL.Experimental conditions of the wing airfoil models were;model chord length of 14cm,Mach number range of 0.63 to 0.80,and Reynolds number of 7 to 14 million.The test results showed inclusively good agreement with the results obtained at other wind tunnel tests.These results came from the tests of the lower Reynolds number (4.8～5.2 million) at 2m×2m transonic wind tunnel.For the tests at the Ludwieg tube,the shock wave movement on the upper surface was frequently observed in the short duration run time of 0.05 second.Finally,the constrictions and problems of the Ludwieg tube tests and the approach to the solutions were discussed.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
