An experimental study for improving the aerodynamic characteristics of wing-body configuration RLVs has been conducted. The fuselage cross-sectional configurations are isosceles right triangle and square with rounded corners. The models have single-delta wings modified NACA0010 with 45deg sweepback angle. The experiments were conducted in a transonic and supersonic wind tunnel at ISAS(Institute of Space and Astronautical Science), JAXA(Japan Aerospace Exploration Agency). The experimental results have shown that the model with isosceles right triangle cross-sectional configuration had good aerodynamic characteristics in the region from subsonic to supersonic. i.e. triangle model has better lift coefficient and lift-to-drag ratio than square model.
