| description abstract | A study of data from various wind-tunnel tests of horizontal tail surfaces was made to determine the accuracy with which section data can be used to estimate the hinge-moment characteristics of control surfaces of finite span. The study consisted of a comparison between the variation of elevator hinge moments with elevator deflection and with airplane pitching moment, as estimated from data obtained in two-dimensional flow, and that variation measured experimentally on 16 different horizontal tails mounted on wind-tunnel models of complete airplanes. The method used in applying section data to the evaluation of three-dimensional characteristics is outlined, and summary curves showing the variation of the major parameters with control-surface chord, balance chord, and trailing-edge angle are presented. It is demonstrated that the three-dimensional hinge-moment characteristics of tail surfaces can be derived from existing section data with an accuracy which is within the tolerance required in preliminary design. | |
