Abstract:

The patent relates to a device whereby a drogue chute is used to extend a long line transducer array in the water as it is being towed in or played out in an ocean current. To avoid problems during a subsequent retrieval of the array, the drogue chute is disconnected. For this reason a release mechanism is interposed between the transducer array and the chute. This release mechanism provides for a nonabrupt separation of the array from the chutes riser straps. An electronic circuit in the mechanism initiates the separation of a first riser strap to dump the entrained water and next, the second riser to completely sever the chute from the array.
