Reduction of Forces and Moments Taken on Internal Balances and the Effect of Axes Orientation

Abstract

To present a uniformity in definitions concerning the relationships between forces and between moments for various reference systems and to clarify the effect of rotation of the model on the balance, rotation of the sting, etc. The notes consider three primary and related topics: (a) a convention of definitions, directions, and angles, (b) a consideration of model body axes, wind axes, and stability axes, and (c) some equations considering movement of the model with respect to the balance, or movements of model and balance with respect to the tunnel.
