High-subsonic damping-in-roll characteristics of a wing with the quarter-chord line swept back 35 degrees and with aspect ratio 3 and taper ratio 0.6
Year: 1949
Abstract: INTRODUCTION
An extensive investigation of the effects of compressibility on the damping-in-roll characteristics of various wing plan forms is being conducted in the Langley high-speed 7-by 10-foot tunnel. The 35° swept-back wing of aspect ratio 3 and taper ratio 0.6 employed in the present investigation was that used in the high-speed wind-tunnel investigation of the tailless model reported in reference 1. The present investigation was carried out on a free-rotating apparatus with the purpose of determining the effects of compressibility and angle of attack on the damping-in-doll characteristics of the wing, with and without the vertical fins that were used on the tailless model reported in reference 1.
