Abstract:

An underwater sound source with a remote controlled actuator comprising a oy having a buoyant portion, a plurality of launch tubes storing acoustic charges, a radio transceiver, control circuitry, hinged doors at the bottom of the tubes, and a safety release circuit. The hinged doors are secured by pneumatic actuators to allow a selected door to open on a radio signal from a remote location. The charges are pressure sensitive and will explode at a preselected depth. A launch platform can deploy the device and remove itself from the general vicinity of the test site. The device releases the charges on command from a transmitter aboard a vessel and reports on the status of the launch tube doors to a receiver aboard a vessel. A safety valve can be opened automatically or on power failure to insure that all acoustic charges have been discharged.
