Project ARTEMIS. High Power Acoustic Source. Interim Report on Acoustic Performance

Abstract

This report describes and presents the results of acoustic tests with the partially completed ARTEMIS source array at limited power levels. The purposes of these tests were to obtain impedance characteristics, response data and transducer displacement as a function of power, frequency and operating depth. Results indicate large variations in displacements over the face of the transducer, Results in peak values in excess of those predicted on the basis of radiated power. A tentative maximum efficiency in excess of fifty percent was obtained subject to an assumed directivity pattern and hydrophone sensitivity. Spurious mechanical resonances were observed as evidenced by the impedance diagrams.
