APPARATUS FOR DEPLOYING AND SUPPORTING A LARGE APERTURE VOLUMETRIC ARRAY IN A MEDIUM The Government has rights in this invention pur- suant to Contract No. N6601-83-C-0301 awarded by The Department of the Navy. ABSTRACT OF THE DISCLOSURE An apparatus for supporting a large volumetric array of acoustic sensors in water is packaged in a standard configuration sonobuoy envelope and utilizes conventional sonobuoy deployment components. A housing within the envelope contains a plurality of tubular extendable members stored on drums and a drive means for extending the members upon deployment of the apparatus. A plurality of releasable array modules are releasably attached to the housing, each module containing an array cable and a plurality of acoustic sensors secured to and along the cable. As the apparatus enters and descends through the water, the tubular members extend to form array support booms. The array modules are synchro- nously released to the extension of the tubular members and as the modules descend, the array cables and acoustic sensors deploy, the array cables forming cate- naries between points on array support boom pairs or between the housing and a points on the various booms. A non-rigid, four-boom hanging catenary array structure is thereby deployed. -1-
