Hydrophone Drogue.

Abstract

The patent application relates to a non-fouling, high drag, packageable drogue for substantially reducing the current flow past a suspended hydrophone. A single rectangular sheet capable of high density packaging in a sonobuoy cannister is selectively sized to provide the desired drag area. Upon deployment the drogue is held in an open widthwise position by upper and lower resilient spreaders and in an open lengthwise position by the weight of the hydrophone thereby obviating possible collapse or fouling as the relative current flow diminishes.
