Effect of high-lift devices on the longitudinal and lateral characteristics of a 45 degrees sweptback wing with symmetrical circular-arc sections
Year: 1948
Abstract: INTRODUCTION
As a part of the general investigation of the landing characteristics of wings for transonic and supersonic airplanes, tests have been made in the Langley full-scale tunnel to determine the aerodynamic characteristics of wings with several different plan forms having circular-arc sections A previous paper (reference 1) presents the aerodynamic characteristics of a 45O sweptback wing having a taper ratio of 0.5 and an aspect ratio of 3.5. This paper contains the longitudinal characteristics for a number of 0.20c plain leading-edge and trailing-edge flap configurations and the lateral characteristics for one flapped arrangement of the aforementioned wing- Also determined was the effectiveness of several combinations of chord wise fences and of a rounded leading edge installed on the outer semispan in alleviating the inherently poor stalling characteristics of this type of wing (references 1 and 2). All the tests were made at a Reynolds number approaching the full-scale value for a small fighter-type airplane and at a Mach number low enough so that compressibility effects were negligible
