Transducer geometry for amplification of axial load response and suppression of non-axial response

Abstract

This present disclosure is about a wind tunnel balance axial section. A wind tunnel balance is a sensor that measures six force/moment components from a test model in a wind tunnel. An axial section, one of the six measurement sections in the balance, is the hardest section to design because it is often required to measure an axial force which is much smaller than other force components. Therefore, there is a specific design requirement for the axial section to selectively amplify the axial force response and suppress the non-axial responses. This disclosure presents a sensor mechanism composed of elastic linkages to achieve this design requirements for the axial section.
