Effects of a fuselage and various high-lift and stall-control flaps on aerodynamic characteristics in pitch of an NACA 64-series 40 degrees swept-back wing
Year: 1947
Abstract: INTRODUCTION
The low-speed aerodynamic characteristics of a 40° swept-back wing of aspect ratio 4, taper ratio 0.625, and NACA 641-112 sections were reported in reference 1. This wing, like many swept-back wings, was longitudinally unstable at the stall because of wing-tip stalling and had relatively low values of maximum lift coefficient even with semispan split flaps, In an attempt to alleviate tip stalling and/or increase the maximum lift, tests have been made of the wing equipped with leading-edge flaps, outboard upper-surface flaps, and split flam hinged at the wing trailing edge. These tests were made at Reynolds number values of 3,040,000 and 6,840,000.
In order to investigate the effect of a fuselage on the aerodynamic characteristics of the wing, tests have also been made of this wing with a fuselage in low, middle, and high positions. The tests were made to determine the characteristics in pitch at Reynolds number values of 3,040,000 and 8,090,000.
