An aerodynamic design study of a series of lifting bodies at angles of attack from 10 to 53 degrees at Mach numbers from 2.30 to 4.62

The aerodynamic characteristics in the transition from high to low angles of attack at supersonic speeds have been experimentally and theoretically studied for a series of lifting bodies with various upper and lower surface camber designs. The configurations under consideration have a 75-degree swept delta planform with a rounded nose. Data obtained indicate that changes in the camber design cause some distinct changes in the aerodynamic characteristics that shoud be taken into account in the selection of a lifting body shape. The flat bottom designs with upper surface camber are found to provide greater drag for retardation at high angles of attack but are considerably out of trim longitudinally. The flat top designs with lower surface camber provide less drag at high angles of attack but can be more easily trimmed. Calculated results are found to be in good agreement with the experimental data.
