FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, namely to the retractable devices of submarines. The hydrodynamic vibration dampener of the submarine retractable device is built into the cylindrical case of the mast of the retractable device. In the aft part of the cylindrical case of the mast of the retractable device, a number of holes with a diameter of 0.1-0.2 diameter of the mast are made at distances from each other equal to 0.5-2 of the diameter of the mast to supply water jets at a speed of 2.5-5 times the speed of the incoming flow.
EFFECT: eliminating the occurrence of intense vortex vibration of the submarine's retractable device is achieved, as well as increasing its reliability and survivability.
