| description abstract | INTRODUCTION In order to minimize drag at supersonic speeds, thin wings of low aspect ratio and relatively sharp leading edges have been proposed. A tapered wing of this type with an aspect ratio of 2.5 and thin hexagonal airfoil-sections was investigated at low speed in the Langley 19-foot pressure tunnel. The results of the lateral-control investigation of the wing equipped with 0.75-semispan and 0.40-semispan flap-type and spoiler ailerons are the subject of the present paper. The lateral-control characteristics were determined for the ailerons with several combinations of fuselage, droop-nose flap, and trailing-edge flaps. Inasmuch as the results of references 1 and 2 have indicated that improvements can be made in the rolling effectiveness of flap-type ailerons at transonic and supersonic speeds by thickening the trailing edges, the lateral-control characteristics of the 0.40-semispan aileron were also investigated on the wing with the trailing edge modified to three different thicknesses. In addition, the tests included measurements of-the instantaneous pressure differential between the upper and lower surfaces at four spanwise stations. | |
