Abstract

A small barrel-stave flextensional transducer, designed and tested at Defence Research and Development Canada - Atlantic (DRDC Atlantic), is a candidate source for underwater coastal surveillance and acoustic communications applications. This high-power transducer (in excess of 190 dB re 1 ?Pa @ 1 m) has an outside diameter, length and mass of 5.7 cm, 12.7 cm, and 1.1 kg, respectively. The measured fundamental flexural resonance frequency was 1.8 kHz with a transmitting voltage response of 118 dB re 1 ?Pa/V @ lm and an omnidirectional radiation pattern. Two computer models were developed for this transducer using finite element codes MAVART™ (Model to Analyze the Vibrations and Acoustic Radiation of Transducers) and ATILA (Analysis of Transducers by Integration of Laplace equations). Comparisons are made between the calibration measurements and the model predictions. [Summer student supported in part by Sensor Technology Limited.].
