Hirosaki Bunka Center), Hirosaki, Aomori, Japan, The supersonic parachute has been used to many space probes for aerodynamic deceleration at the time of the atmospheric re-entry. However, its detailed aerodynamic characteristics have not been made clear. The purpose of this study is to investigate basic flow phenomena and aerodynamic characteristics on a rectangular concave body in supersonic flows by means of high-resolutional numerical computations using the WENO scheme. As results, the following characteristics have been captured: 1) in the case of quasi-stationary flows, vortices are shed from the detached bow shock wave, and especially in mean stream Mach number greater than three the vortices are to flow toward the inner portion of the concave body; 2) in time history of lift coefficients, peaks of low and high frequencies are observed in the FFT analysis, and the former and the latter oscillations are due to the outer and inner regions of the body, respectively; 3) in the transient cases when disturbances are given, pressure waves go and return in the space between the detached shock wave and the concave bottom, and vortices are shed from the center portion of the shock wave, with movements of shock location., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530023025, レポート番号: JAXA-SP-14-010},
