Problems solved by technology

[0003] In this traditional ship propulsion device, not all of the fluid in the tunnel unit is accelerated by the propeller, and part of the fluid flows away through the gap, thereby reducing the propulsion efficiency
[0004] In addition, in conventional ship propulsion devices, vibration waves generated at the end of the propeller and transmitted to the tunnel unit through this gap will increase the vibration noise of the hull

Embodiment Construction

[0027] Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings, any same or corresponding reference numerals are given the same or corresponding reference numerals without repeating them.

[0028] figure 1 It is a structural diagram of a section of a ship propulsion device according to an embodiment of the present invention. refer to figure 1 , the propulsion device 1 of the present invention includes a tunnel unit 10 , a propeller 20 , a drive unit 30 , a shaft 40 and a jet flow supply unit 50 . In this propulsion device 1, the jet fluid supplied by the jet flow supply unit 50 is ejected from the end of the propeller 20, and air bubbles are formed between the end of the propeller 20 and the inner surface of the tunnel unit 10, thereby improving the propulsion efficiency , and reduce the vibration noise of the hull. Here, the spray fluid may include air or water.

Abstract

The present invention relates to a propulsion apparatus for a marine vessel and to a marine vessel comprising same. The propulsion apparatus for a marine vessel according to one embodiment of the present invention comprises a tunnel unit; a propeller which rotates within the tunnel unit to generate propulsive force, and one end of which has a jet fluid outlet port; a driving unit which provides driving force for rotating the propeller; shafting for transmitting the driving force of the driving unit to the propeller; and a jet fluid supply unit which supplies jet fluid to the jet fluid outlet port such manner that a jet fluid layer is formed between the end of the propeller and an inner wall of the tunnel unit.

Description

technical field [0001] The invention relates to a ship propulsion device and a ship including the ship propulsion device. Background technique [0002] A side thruster is a ship propulsion device that generates propulsion by installing a propeller inside a tunnel unit in which a gap is formed between the end of the propeller and the tunnel unit to prevent the propeller from interfering with the tunnel Mutual interference between units. [0003] In this traditional ship propulsion device, not all of the fluid in the tunnel unit is accelerated by the propeller, and part of the fluid flows away through the gap, thereby reducing the propulsion efficiency. [0004] In addition, in a conventional ship propulsion device, vibration waves generated from the end of the propeller and transmitted to the tunnel unit through the gap will increase the vibration noise of the hull. Contents of the invention [0005] technical problem [0006] An embodiment of the present invention provi...
