FIELD: shipbuilding.
SUBSTANCE: invention relates to the field of shipbuilding, namely propellers with reduced levels of vibration and radiated noise. The propeller contains a hub, blades and a gasket made of vibration-damping material between them. The blades have an internal cavity filled with vibration-absorbing material. The width of the blade cavity and the thickness of the vibration-absorbing material filling the blade do not exceed 5 mm.
EFFECT: maximum reduction of vibration levels at resonant frequencies is achieved.
