FIELD: transportation.
SUBSTANCE: propulsive arrangement contains the carrier rack, the casing with the propeller at its end, the annular nozzle. The annular nozzle is rigidly fixed to the casing by the support structure, that includes at least three blades. The nozzle has the inlet and the outlet, whereby the water flow channel is formed between the inlet and outlet through the inner area of the annular nozzle. The propeller pulls the ship in the direction of the movement (S1). The support structure is located between the propeller and the carrier rack in the direction of the ship movement (S1). The blades of the support structure are located between the outer perimeter of the casing and the inner perimeter of the nozzle for receiving the water flow from the propeller blades.
EFFECT: improvement of the propulsive arrangement.
