Spring Tabs: A Review of their Development and Application, Together with an Outline of the Design Data Involved

The first step in calculating stick force is to modify the wind tunnel hinge moment curves. This is done by obtaining a curve for b1 at various incidences, and then altering the measured hinge moments in accordance with the formula in para. 15. Numerical examples of this process are given in Tables 1, 2, 3, and the new hinge moment curves plotted in figs. 25, 26, 27.
