| description abstract | INTRODUCTION A systematic investigation of the control-surface characteristics, particularly the hinge-moment parameters, of horizontal-tail surfaces has been undertaken by the NACA to provide experimental results for a comparison with those parameters computed by lifting-surface theory. The investigation was to include a study of the effects of sweepback on the horizontal-tail lift and hinge-moment parameters by a comparison of the results of tests of models differing mainly in the angle of sweepback, with the same area, aspect, ratio, taper ratio, and section. In references 1 and 2 the experimental results are presented from wind-tunnel tests of models of aspect ratio 3 and 4.5 without sweep and swept back 35°. The present report extends the experimental data to include an aspect ratio of 6. A comparison of the experimental and theoretical lift and hinge-moment parameters for the models of references 1 and 2 has been presented in reference 3. | |
