A 7 deg half-angle cone model 1100 mm long was designed and manufactured for the study. To change the Reynold's number, stagnation enthalpy was varied from H(sub 0) = 3.5 MJ/kg (Re = 6.0 x 10(exp 6) /m) to H(sub 0) = 8.7 MJ/kg (Re = 1.6 x 10(exp 6) /m). Seventy-two miniature co-axial thermocouples were flush-mounted on the surface of the model to measure heat flux distribution. Surface pressure fluctuation was measured in order to observe the second-mode instability in the boundary layer. The heat flux distribution measurement indicated that transition occurred on the model at approximately Re = 4.0 x 10(exp 6). Surface pressures exhibited peaks in their frequency spectra that were thought to represent second-mode instability. Schlieren high-speed video showed disturbances in the vicinity of the model surface at the location where laminar-turbulent transition occurred., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, Wind Tunnel Technology Association Meeting, 資料番号: AA0064475004, レポート番号: JAXA-SP-09-005}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {高温衝突風洞HIESTにおける極超音速境界遷移研究について}, volume = {JAXA-SP-09-005}, year = {2009} }
