Abstract

The special-purpose internal strain-gage balance described was developed to measure low rolling moments in a trisonic wind tunnel. The balance is of floating-frame type and its sensing element is a crossed-flexure pivot formed by four strips connecting the outer sleeve to the inner rod. This type of balance may be used in all situations requiring accurate rolling moment measurement of low magnitudes, as in the measurement of roll control effectiveness and the roll-damping derivative
