Marine water jet T-shaped hydrofoil rudder

Abstract

The invention discloses a ship water spray T-shaped hydro-flap in the field of fluid dynamics of a ship. The hydro-flap comprises a water spray T-shaped hydrofoil, a rotating shaft and a first push rod, wherein the rotating shaft is connected with the water spray T-shaped hydrofoil, one end of the rotating shaft is connected with a water cooling system of a ship body, and cooling water of the water cooling system of the ship body is injected into the T-shaped hydrofoil through the rotating shaft so as to make the T-shaped hydrofoil generate spraying power; one end of the first push rod is connected with a steering engine, and the other end of the first push rod is connected with the rotating shaft so as to drive the water spray T-shaped hydrofoil to rotate through the rotating shaft. The water spray T-shaped hydrofoil comprises a horizontal wing, a vertical wing and a torpedo body, wherein the horizontal wing is horizontally arranged in an axial direction of the torpedo body, the vertical wing is vertically arranged in a radial direction of the torpedo body, a water channel communicated with the rotating shaft is formed in the torpedo body and the rotating shaft is vertically arranged in the middle of the vertical wing. According to the ship water spray T-shaped hydro-flap provided by the invention, the ship can be steered by the kinetic energy of the cooling water sufficiently under the condition of no navigational speed.

Description

technical field [0001] The invention relates to a device in the field of hull fluid dynamics, in particular to a marine water jet T-shaped hydrofoil rudder. Background technique [0002] Surface unmanned platforms generally refer to unmanned boats, power ship models, remote control speedboats, etc. Surface unmanned platforms have broad applications in both military and civilian fields, such as military unmanned combat boats, reconnaissance boats, research boats for scientific research, small reservoir rescue boats, racing electric boats, etc. For small power boat models, the propeller is usually driven by an inner rotor brushless motor or a small gasoline engine of 26cc-30cc. At present, high-power marine brushless motors and small gasoline engines require cooling systems, and the commonly used cooling systems are composed of diaphragm pumps, water inlet pipes, cooling spiral pipes and water outlet pipes. The diaphragm pump draws water from the water inlet pipe, flows thro...

Problems solved by technology

However, the disadvantage of this technology is that it cannot use the kinetic energy of the cooling water discharged from the ship's cooling system, nor does it have the steering performance of the rudder, let alone realize the steering function when the ship has no speed.

However, the disadvantage of this technology is that the water-jet rudder relies on the high-speed water jet, which needs a special water jet to realize it, which means that it consumes extra energy, and this technology does not have the ability to reduce pitch and heave and provide lift capacity
