Abstract

A novel fiber optic differential pressure transducer and multiplexing system is described for real-time pressure measurements of airflow on an actuator- and SMA-controlled airfoil. The design of the pressure transducer is based upon extrinsic Fabry-Perot interferometric technology and incorporates a micromachined silicon diaphragm as the pressure sensitive element. The pressure transducer has a full scale operating range of -10 to 10 psi_g and a resolution of greater than 0.01 psi. Data is presented demonstrating the reproducible performance of the fiber optic sensor after repeated cycling and also at various temperatures. Finally, various multiplexing techniques and results are described.
