Underwater Acoustic Source

Abstract

Efforts were directed toward the development of a mechanical underwater sound transducer having an omni-directional one-plane radiation pattern, a frequency of 5 to 20 kc, and a power output of 1 w for a minimum of 8 sec. Three devices were considered: a fluid-driven diaphragm, a water-hammer device, and a Hartmann generator. The first 2 were to operate on pressurized water, and the third device was to operate on pressurized air. These devices did not have the necessary power output, and they required stored energy for operation. Possible uses of the devices are discussed, and theoretical and design data are included.
