並列タイトル等Oil Flow Patterns on a Series of Capsule-Type Re-Entry Vehicles at Hypersonic Speeds
タイトル(掲載誌)航空宇宙技術研究所資料 = Technical Memorandum of National Aerospace Laboratory
一般注記Oil flow visualization tests have been made to examine various fore-and afterbody flow patterns on a series of capsule-type vehicles at a Mach number of 7.1 and at angles of attack from 10 to 20 deg. 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.
