Abstract

An analysis of the principal results of recent control-surface research pertinent to transonic flight has been made. An indication of the nature of the changes in control-surface characteristics above the critical speed of the wing and a preliminary design procedure for estimating the effectiveness of flap-type controls on swept wings are presented.

Investigation of Horn Balances on a 45 Degree Sweptback Horizontal Tail Surface at High Subsonic Speeds

A wind-tunnel investigation of horn balances on a 45 degree sweptback, semispan, horizontal tail surface was made to determine the effects of horn size and inboard-edge fairing at a Mach number of 0.30 and to determine the effects of compressibility up to a Mach number of 0.89. Presented are lift, drag, pitching-moment, and hinge-moment data and lift and hinge-moment parameters.
