ABSTRACT:
A flextensional sonar transducer may comprise an elliptical shell which, during manufacture of the transducer, has been distorted to permit insertion of stacks of piezo-electric ceramic plates and then released to grip the stacks and maintain them in compression, even when at design depth. The distortion requires substantial loading and may damage the shell. Herein, the undistorted shell is fitted with the ceramic plate stacks and an adjustable wedge device which is settable to provide the required pre-load. The wedge device may be coupled to an actuator, pressure sensor combination which automatically maintains a desired pre-load for different depths.
