Tests in the Ames 40- by 80-foot wind tunnel of an airplane configuration with an aspect ratio 3 triangular wing and an all-movable horizontal tail - longitudinal and lateral characteristics
Year: 1953
Abstract: INTRODUCTION
Wind-tunnel tests at subsonic and supersonic speeds have been made for small-scale, aspect ratio 3 triangular wings. In order to extend the scope of data on the aspect ratio 3 triangular-wing plsm form to that of large scale, an investigation has been conducted in the Ames . k)- by 80-foot wind tunnel.
For purposes of paralleling previous investigations of airplane configurations with aspect ratios 2 and 4 triangular wings in the 40- by 80-foot wind tunnel (refs. 1, 2, and3), en aspect ratio 3 triangular wing with an NACA 0005 (modified) section equipped with trailing-edge partial-span slotted flaps of constant chord was tested in combination with a fuselage, vertical tail, and horizontal tail. This combination was identical to that used in the previous investigation. In addition to symmetrical control deflections, the flaps and horizontal tail were deflected asymmetrically and a limited investigation of their use as lateral-control devices was made.
The results are presented herein without analysis in order to expedite publication.
