METHOD FOR FABRICATION OF MULTI-ELEMENT SECTION FOR HYDROACOUSTIC ANTENNA Russian patent published in 2017 - IPC H04R31/00 G01S15/00 

FIELD: radio engineering, communication.

SUBSTANCE: antenna comprises piezoelectric rod transducers, mounted in a sealed housing, a common plate made of flexible polymeric material with blind holes with the depth 0.2-0.3 of the outer diameter of the sealed housing of the piezoelectric rod transducer. Each piezoelectric transducer is mounted into the blind hole of the common plate with tight fixing; the common plate is placed into a mould. This common plate is shaped in required manner, the electrical installation of the multi-element section is performed, of sealing elements the mounting and fastening elements of the multi-element section in the sonar antenna are installed and fixed in the mould, the mould is filled with the polymer compound with adhesion to the elastic polymer common plate, and polymerization of the polymer compound is performed.

EFFECT: reduced labour intensiveness.
