Popis:	Comprehensive HB-2 standard model tests are underway in the hypersonic wind tunnels in JAXA. The HB-2 force/moment test in Mach 10 flow was conducted in the 0.44 m Hypersonic Shock Tunnel (HST) with a new model support system. Vibration acceleration that is contaminated in the force/moment measurements was eliminated applying 'Oscillation identification technique'. The results of longitudinal characteristics were different from those obtained at the 1.27 m Hypersonic Wind Tunnel (HWT2). The sting bar of a new model support system seemed harmful. A significant improvement was observed when a wedge-type cover is attached to the bar. However, unsymmetrical feature still remains in the axial force. Detailed flow investigation with a new model support system is urgent. 資料番号: AA0049495002 レポート番号: JAXA-SP-05-019
