To investigate the effect of the Reynolds number, it was varied from 4.5×104 to 1.8×105 based on aunit length (cm). Model configurationsare classified into two types: blunt cone (S-type) and capsule (M-type). Oilflow photographs indicate that several S-type models show bubble type separations just downstream of the nose-cone juncture region at an angle of attack of α=20゜. However, no separations occur at an angle of α=10゜. Contrary to the results for the S-type, M-type models reveal complex flow separation patterns on the afterbody surface, which depend on model shapes, angles of attack and Reynolds numbers. In this report, these oil flow patterns are analyzed in detail by using topological rules., 資料番号: NALTM0557000, レポート番号: NAL TM-557}, title = {カプセル型回収体の極超音速オイル・フロウ試験}, year = {1986} }
