In order to enhance the lift to drag ratio of advanced space planes, the concepts are based on delta wing configurations. High speed vortices whose strength depends on angle of attack, considerably increase the lift. Because of their importance for aerodynamical forces, many investigations were performed using only flat wing configurations. Here, the integration of the delta wing in a space plane and additional interactions with propulsion systems or winglets were investigated using smoke wire method in a Subsonic-Wind-Tunnel.
