Popis:	In the present paper, results of force and heat flux measurement tests conducted in the JAXA 1.27 m Hypersonic Wind Tunnel (HWT) using the HB-2 standard model are presented. The tests were conducted at a nominal Mach number of 10, a stagnation enthalpy of 1 MJ/kg, and stagnation pressures from 1 to 6 MPa. Both for the force and heat tests, good data repeatability were confirmed. The heat transfer coefficient obtained from the IR thermography agreed well with the one from the thermocouple measurement. On the other hand, a conventional uncertainty estimation method which estimates the bias and random error components was applied to the force test data, whereas Monte Carlo approach was utilized to numerically estimate the uncertainty in the data reduction process of the heat flux data. The present experiment was conducted as a series of comparison test campaign between two hypersonic facilities in JAXA. The present test data is also expected to serve as a set of database for the validation of hypersonic computational fluid dynamics (CFD) codes. 資料番号: AA0049211008 レポート番号: JAXA-SP-05-016
