Abstract

Изобретение относитс  к судостроению . Целью изобретени   вл етс  повышение эффективности гидроакустического обтекател  путем снижени  воздействи  на работу гидроакустической станции направленных судовых источников шума. Цель достигаетс  тем, что пространство 8 между наружным.и внутренним сло ми звукопроз- рачной оболочки от фланцевого соединени  3 до плоскости, перпендикул рной продольной оси обтекател  и проход щей через вертикальную ось гидроакустической станции 7, выполнено в виде водонепроницаемых полостей, соединенных трубопроводами 9. 10 и 11. с системой их заполнени  и осушени , при этом фланцевое соединение размещено в корму от акустического экрана 4. 1 з.п.ф-лы. 2 ил.The invention relates to shipbuilding. The aim of the invention is to increase the efficiency of the sonar fairing by reducing the impact on the operation of the sonar station of directional marine noise sources. The goal is achieved in that the space 8 between the outer and inner layers of the soundproof shell from the flange connection 3 to the plane perpendicular to the longitudinal axis of the cowling and passing through the vertical axis of the sonar station 7 is made in the form of waterproof cavities connected by pipelines 9. 10 and 11. with a system for filling and draining them, wherein the flange connection is located aft of the acoustic screen 4. 1 zppf. 2 ill.
