Device, for reducing noise and absorbing vibrations for warships and frigates, comprises unit placed in nacelle and consisting of uncoupling isolation vibration damping mounts arranged between motor and inner wall of nacelle

摘要

An absorption device absorbs vibrations generated by an electric motor that is built into a propulsion pod of a ship. The propulsion pod contains an electric motor that is cooled by circulation of a radial airflow within the propulsion pod. The electric motor rotationally drives at least one propeller through a transmission shaft. The absorption device is disposed in the propulsion pod to position and hold the electric motor inside the propulsion pod and also to filter the vibrations emitted by the motor and channel the motor cooling airflow circulation.
