ABSTRACT:
This invention is a parachute array in which a plurality of hydrophones are attached to the skin of a planar or volumetric parachute or affixed to strings that are positioned around a planar or volumetric parachute. When the parachute is moved through water, the parachute will expand and provide the necessary tension forces to maintain and position the hydrophone array in a particular geometric orientation without the use of any rigid structural members.
