Abstract
A noise damping system incorporating in the hull of an underwater torpedo or the like which includes a power plant having a boiler. An inner hull section includes hotwell passages about the boiler whereby subcooled liquid in the hotwell passages absorbs heat from the boiler. A noise damping elastomer layer is provided about the inner hull section whereby the hotwell passages insulate the noise damping layer from the boiler. An outer hull section has condenser passages about the noise damping layer. The hotwell passages and the condenser passages are part of the closed circulation system of the power plant.
