ABSTRACT:
A six component balance for use in measuring forces and moments on an aircraft model in a wind tunnel or the like. The balance is mounted on a wind tunnel sting by means of a sleeve that surrounds and is spaced from a central core. The central core is connected to a model by support bars passing through slots in the sleeve from the core. Core ends are secured to the sleeve and support the central core through a plurality of webs. A plurality of strain gages are mounted on the webs to detect strain on the webs resulting from forces and moments applied to the model. This system measures six components, i.e., lift force, drag force, side force, pitching moment, yawing moment and rolling moment.
