Three types of models were fabricated : (1)a verificatioin model (hemisphere cylinder with a diameter of 50 mm), (2)a 1/100 scale nose model of the HOPE (H-II Orbiting Plane), and (3)a 1/100 scale wing-body model of the HOPE. They are made with a carbon fiber skin as thin as 1.5 mm, and a ceramic internal structure. Time histories of surface temperatures were measured by using an infrared thermograph system. Surface heat transfer rates were estimated from the measured surface temperatures and their time derivatives. The heat transfer distribution on the verification model showed reasonable agreement with existing theory. For both the nose model and the wing-body model, the surface heat transfer rates decreased monotonically along the lower centerlines, and increased with the angle of attack. For these models, thermographs of the surface heat transfer distribution are also shown. From these results, we confirm that the present method of estimating surface heat transfer rate is justified, and that the present experiment on surface heat transfer is not only applicable but also useful in an arc-heated wind tunnel., 資料番号: NALTR1048000, レポート番号: NAL TR-1048}, title = {アーク加熱風洞による表面熱伝達の実験}, year = {1989} }
