Development of Dynamic Force Measurement Capabilities at AEDC Tunnel 9

Abstract

This work focuses on the development of a hybrid force balance technology that uses piezoelectric sensors in series with conventional strain gauge balance technology to enable broad frequency range force measurements in hypersonic wind tunnel test facilities. Here, sensitivity analyses are carried out to examine the effects of design parameters, including the thickness of mounting plates and location of calibration loading points on the reliability of force and moment measurements.
