MULTIPLE-ELEMENT LINEAR DISCRETE HYDROACOUSTIC ANTENNA Russian patent published in 1997 - IPC

FIELD: design of hydroacoustic devices. SUBSTANCE: device has cylindrical air-filled elements with holders which have central holes which are located along axis of polymer hose which is filled with compound. In addition device has line of electric communications. Each holder is designed as solid cylinder which is made from elastic polymer material, is tied on end side to ends of adjacent piezoelectric elements and to carrying hawser which runs along axis of hose. In addition device has cases which center piezoelectric elements for their inner diameter. EFFECT: simplified design, sharp beam pattern. 4 cl, 2 dwg
