DEVELOPMENT OF A MINIATURE PRESSURE TRANSDUCER FOR APPLICATION TO AIR FOIL STUDIES IN THE SHOCK TUBE

摘要

A miniaturized pressure transducer was developed to measure the pressure on an airfoil in the shock tube. The transducer is only 1/8 inch thick, and furnishes a signal of about 0.1 volts per psi Barium titanate was used as the element. The problem of charge leakage was solved. The sirain and vibration sensitivity was considerably reduced, as was the thermal sensitivity. These questions are discussed in detail, and the final configuration is presented from which transducers can be built.
