AERODYNAMIC CHARACTERISTICS IN PITCH AT A MACH NUMBER OF 2.01 OF SEVERAL WING-BODY COMBINATIONS WITH WEDGE-SHAPED BODIES LOCATED ABOVE AND BELOW A 54.5° SWEPT DELTA WING

摘要

An investigation has been conducted at a Mach number of 2.01 to determine the aerodynamic characteristics in pitch of several model configurations with wedge-shaped bodies located above and below a 54.5° swept delta wing. The inves¬tigation included tests on bodies of wedge-shaped planform with variations in body wedge angle, body height, and body length. Measurement of the lift, drag, and pitching-moment coefficients for the various wing-body combinations were made through an angle-of-attack range of about -5° to 10°.nThe results of the investigation indicated that large changes in lift-drag ratio occurred as a result of the wing-body interference effects produced by the presence of the combined wedge-shaped bodies located above and below the delta wing.
