Abstract

Subsonic, transonic, and supersonic aerodynamic loads data are presented for the center fin and the control surfaces of the HL-10 lifting body vehicle. The effects of variations in angle of attack, angle of sideslip, aileron deflection, rudder deflection, and Mach number on the center fin loads are presented in terms of coefficient slopes. The effects of vehicle attitude, control surface deflection, Mach number, and rocket engine operation on the outboard and inboard tip fin flaps, rudder, elevon flap, and elevon hinge-moment coefficients are discussed. The flight test aerodynamic loads are compared with full-scale and small-scale wind-tunnel data.
