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.
