FIELD: transport.
SUBSTANCE: movement acceleration device of surface and subsurface ships is installed on left-handed and right-handed boards below water line and contains gear box with conical gear wheels, and impeller. Impeller is made so that it can be rotated from shaft of the main engine and from operation of independent engine as auxiliary propeller in addition to the main propeller. Impeller is equipped with water collector at the inlet and with connection pipe at the outlet, located in the ship's body cavity and consists of hollow design in the form of a circle, inside which there are blades. Blades are rigidly fixed with discs and have backward bending. For water to pass in the centre of one disc, there is a hole, on the other disc - hole for impeller to be attached to shaft on which a sealing is installed.
EFFECT: increasing service performance of ship and economy of engine fuel.
