Analysis of Available Data on Control Surfaces Having Plain-Overhand and Frise Balances

Abstract

Empirical relations that will facilitate the prediction from geometric constants of characteristics of balanced control surfaces and are applicable to preliminary design of control surface balances already in use are presented with representative pressure-distribution diagrams. The effects of overhand, nose shape, gap and Mach number are considered. Increase in Mach number decreased deflection range over which balances were effective in reducing slope of hinge-moment curve.
