TECHNIQUES FOR MEASUREMENT OF DYNAMIC STABILITY DERIVATIVES IN GROUND TEST FACILITIES

Abstract

Some of the techniques in current use for measuring dynamic stability derivatives in wind tunnels are described, with emphasis given to the important features of balance system design, data reduction methods, instrumentation and typical balance systems. The use of gas bearings for dynamic stability and roll damping balances is treated and a three-degree-of-freedom balance system employing a spherical gas bearing is described.
