Wind-tunnel investigation of horizontal tails IV : unswept plan form of aspect ratio 2 and a two-dimensional model
Year: 1948
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 procedures.
Experimental results obtained from wind-tunnel tests of unswept and 35º swept-back plan-form models aspect ratios 3, 4.5, and 6 are presented in references 1, 2, and 3. The present report extends the experimental data to include an aspect ratio of 2 and in addition, presents section data which are necessary for the lifting-surface-theory computations. A comparison of the experimental and theoretical results for the unswept and the swept-back plan forms of aspect ratios 3 and 4.5 has been presented in reference 4.
