• Note (General): 20-21 May 1999 (62nd). 25-26 Nov. 1999 (63rd); 感圧塗料(PSP)は計測原理が化学反応に拠っているため温度依存性が高く、模型表面温度の変化が計測誤差につながりやすいため、模型表面温度が時々刻々と変化する吹き出し式風洞における適用は困難とされていた。そこで、感圧塗料と類似の計測原理、装置で温度を計測する感温塗料(TSP)を感圧塗料と併用することによって模型表面上の圧力分布と温度分布を同時に計測し、感圧塗料の温度依存性の補正を行うPSP/TSP複合較正法の吹き出し式風洞試験における有効性を検討するための予備試験を実施した。感圧塗料、感温塗料を塗布したマイラーフィルムを貼付けたSST模型を用いてM=2における超音速風洞試験を実施した結果、40秒間の風洞通風中に模型の表面温度が約5K低下すること、温度補正を行うことによって感圧塗料による圧力データは通風中の6回の計測でほぼ一致すること、さらに感圧塗料の計測結果が従来の圧力孔による計測結果と比較的良好な一致を示すことが明かとなった。; Pressure Sensitive Paint (PSP) depends highly on temperature and so measurement errors are easily caused by temperature changes on the model surface, because its measurement principle is based on chemical reactions. Therefore, its application to a blowdown wind tunnel has been considered to be difficult since the temperature on the model surface changes every moment. By using the PSP together with Temperature Sensitive Paint (TSP), which measures temperature with the principle and apparatus similar to the PSP, the pressure and temperature distributions on the model surface can be measured simultaneously. Thus, a preliminary test to examine the effectiveness of a PSP/TSP combined calibration method in the blowdown tunnel was conducted, in which the correction method of the temperature dependence of PSP could be developed. A supersonic wind tunnel test at M = 2 was conducted by using an SST model on which PSP and TSP coated Mylar films were pasted. As a result, the surface temperature of the model was measured to decrease by about 5 K during a period of 40 s of the wind blowing in the tunnel. The temperature-compensated pressure data by PSP were nearly equal among the results of six measurements. It was shown that the results by PSP were in relatively good agreement with the past results by the pressure hole method.; 資料番号: AA0028634004; レポート番号: NAL SP-45
