An investigation has been made to determine the low-subsonic aerodynamic characteristics of a small-scale 60° delta wing with a spacecraft model attached directly to its lower surface. This configuration was intended to represent a spacecraft with an inflatable wing which would be deployed to give the space craft a glide landing capability following a ballistic reentry. The effect of the relative size of the spacecraft and wing was determined by the use of two different size spacecraft models with the same wing.nThe model was longitudinally stable about the assumed center-of-gravity position and had maximum trimmed lift-drag ratios of about 6 and 5 for the small and large spacecrafts, respectively. The configuration with the large space craft, which was the only one for which lateral tests were made, generally had low positive directional stability up to an angle of attack of about 29° and was unstable at the higher angles.
