FIELD: physics, acoustics.SUBSTANCE: invention relates to shipbuilding and specifically to hydroacoustic station domes. The non-ribbed hydroacoustic station antenna dome consists of an outer layer, an inner layer and a middle layer in between, said layers being made of polymer composite materials, and is characterised by that the middle layer is reinforced with polyaramid fibres, and the outer and inner layers are reinforced with waterproof fibres, wherein the total thickness of the outer and inner layers is not more than 0.25 times the thickness of the middle layer.EFFECT: making a hydroacoustic station antenna dome from composite materials, having high strength and operational reliability with improved acoustic properties.3 cl, 3 dwg |
