NON-RIBBED HYDROACOUSTIC STATION ANTENNA DOME Russian patent published in 2012 - IPC H01Q1/42 

FIELD: physics.

SUBSTANCE: non-ribbed hydroacoustic station antenna dome, having the shape of a hydrodynamically streamlined body which is supported by excess internal pressure and a unit for attaching to the vessel hull in form of an edge of a fairing plate, located in a metal clamp, according to the invention, the fairing plate is reinforced with a polyaramid fabric and contains binder in form of an elastomer. The unit for attaching to the vessel hull is in form of two parallel metal plates, which enclose between themselves an area of the fairing plate, made from polyaramid fabric in form of reinforcing material and epoxy binder, and an area of the transition zone to the rest of the part of the fairing shell in which there is gradual smooth replacement of the epoxy binder by the elastomer binder. Polyurethane is also used as the elastomer binder.

EFFECT: higher strength, resistance to local dynamic loads and improved acoustic characteristics.
