ABSTRACT:
A system for deploying an array of sonar projector transducers includes a housing in which a plurality of disk shaped projectors are stacked, a pair of small diameter cables are reeled from a powered drum for tethering the projectors, the cables being anchored to the bottom projector, a pair of electrical conductors are connected to the projectors, each conductor constituting a series of sections interconnecting electrical connectors fastened to opposite sides of each projector, a centering ring attached to the bottom projector including a series of pressure responsive latches which serve to secure the array in the housing and to release the array upon its reaching a desired depth. Where the drum is actuated the stack is lowered with each projector being successively suspended by its pair of conductor sections, and each of the conductor sections is given a predetermined twist such that when the array is again returned to the housing the conductor sections are caused to form predetermined loops.
