An investigation to determine the aerodynamic characteristics of deflectable wing-tip ailerons on a sweptback wing was made in the Langley high-speed 7- by 10-food tunnel by means of the transonic-bump technique. The basic wing used in this investigation had 51.3 degree sweepback at the leading edge, an aspect ratio of 2.87, and a taper ratio of 0.51.
