Application of Spring Tabs to Elevator Controls

Abstract

Equations are presented for calculating stick force characteristics obtained with a spring tab type elevator control. Main problems encountered in design of a satisfactory elevator spring tab are to provide stick forces in desired range, to maintain force per g (acceleration of gravity) sufficiently constant throughout speed range to avoid undesirable feel of control in ground handling, and to prevent flutter. Examples show design features of spring tabs required to solve these problems for airplanes of various sizes. Some special tab designs, including geared and preloaded spring tabs, are discussed.
