An Experimental Study on the Improvement of Aerodynamic Characteristics Using the Blowing for RLV

다국어 초록 (Multilingual Abstract)

To improve the aerodynamic characteristics of Reusable Launch Vehicles (RLV), active flow control methods with blowing were investigated. The testing models are wing body and lifting body contigurations. The experiments have been conducted in low-speed wind tunnels of Kyushu University and transonic wind tunnel of ISAS (Institute of Space and Astronautical Science), JAXA (Japan Aerospace Exploration Agency). For the active flow control, the blowing along the fuselage surface was chosen. Flow visualization results show that the vortex on the fuselage is greatly moved near the fuselage, and the vortex core of the wing is clearly observed. The aerodynamic characteristics result shows that the blowing increases the lift and lift-to-drag ratio. From those results, we confirmed that the blowing can be useful for the improvement of aerodynamic characteristics of the RLV.
