Emphasis was placed upon the use of leading edge devices as primary controls and also as auxiliary devices with conventional controls. Selected configurations were tested in AEDC 4T facility and limited validation was obtained in the AEDC 16T facility. Control configurations investigated included leading edge flaps and ailerons both singly and in combination, as well as spoilers, differential horizontal tail and several auxiliary devices. Use of differential leading edge deflection significantly improved aileron effectiveness at high-angle-of-attack transonic conditions. Because of the important effects that the wing-body configuration has upon wing mounted control devices, considerable data and analysis are presented for the longitudinal characteristics. Testing of the same model in two different size facilities provided significant information on wall interference effects at transonic conditions.
