錐状流を伴うウェーブライダの空力特性に関する実験的研究 An Experimental Study on Aerodynamic Characteristics of Idealized Conical Waveriders
In this study, flow fields around idealized conical waveriders as well as aerodynamic characteristics are examined experimentally in TMIT hypersonic wind tunnel. Flow fields are observed with a schlieren system and aerodynamic forces are measured by a three-component balance. From the force measurement, the L/D ratio of on-design-/off-design- waveriders are found. The result shows that for waveriders with fins, value of L/D ratio drops as the decrease of angle of attack rapidly, whereas for a half cone, not so suddenly. Moreover from schliren photographs, shock shapes of attach/dettach condition are examined. The these photographs show that for planform-, small- and on designfins, shock shapes are conical, and for a large-fin, the shape is not conical.
