Abstract

Marine device functioning as an inert rudder or active steering member independent of the main propulsion system of the vessel, wherein one or more hydrofoils are mounted eccentrically and rotatably about a vertical axis on a horizontal disc rotatable about a central point. The longitudinal hydrofoil can be controlled by a drive device not associated with the main drive device of the disc, so that when used as an inertial rudder of a ship, the disc is fixed in a suitable position, the longitudinal hydrofoil is aligned by the drive device in the bow-to-stern direction, the drive device also transmits the required rudder oscillation amplitude to the longitudinal hydrofoil, and when acting as an active steering, the disc is rotated according to the required propulsion direction, the separately arranged drive device is controlled, so that the longitudinal hydrofoil generates a movement of the surrounding water, thereby generating a directional thrust.

Description

Marine installations acting as inert rudders or active steering components, independent of main drive

The present invention relates to marine installations having independent reliance on the main propulsion system of the ship, acting as inert rudders or active steering components.

It is known from DE-AS1941652 that by rotating the vertical axis the ship can be flexibly steered in any direction, but this described straight-wing propeller cannot be used as an energy-saving inertial rudder while driving, because the straight-wing propulsion The kinematic characteristics of the propeller and the number of hydrofoils, that is, in the longitudinal direction of the ship and the required rudder angle, the hydrofoil arrangement state with small resistance cannot be realized. When using straight wing propellers, there is no active energy drive to achieve a desired The ship's heading angle is not acceptable.

It is known from DE4443100A1 that with this driving device, although an inertial rudder action and an active propulsion action can be obtained, the movement of the driving device works according to a certain steering law. According to active action, this propeller has the characteristics of a fixed propeller. This propulsion change must be obtained as a function of the rotational speed change. Due to the large structural dimensions of the required planetary gear, this becomes cost-intensive and heavy.

The object of the present invention overcomes these drawbacks, improves existing device, guarantees inertial, little resistance rudder effect and the generation of active thrust with less structure and construction cost.

The solution to achieve the purpose of the present invention is: a marine device that does not depend on the main transmission device of the ship and acts as an inert rudder or an active steering component, wherein a plurality of longitudinal hydrofoils are eccentrically and rotatable around a vertical axis. On a horizontal disk that can rotate around the center point,

By the use of the device inertly, the use of an independently steerable drive independent of the main drive of the puck ensures the required rudder swing, on the other hand by the active use of the device and the rotation of the puck, It makes the relative movement and circumvention of the hydrofoil possible, so as to realize high-efficiency propulsion.

The device according to the invention is illustrated in the drawings, some of the details being omitted, and only a top view of a disc with hydrofoils driven by separately arranged drive means is shown schematically.

Figure 1 depicts the device of the invention with two rudder plates.

In Fig. 1 there is depicted a device which works independently of the main transmission of the ship, not described, and which installs a horizontal disc 2 in an area of the hull not described in detail, one or more water Wing 3, one or more separately arranged drive means 1 controlling the position of the hydrofoil, and a disc 2 drive means not depicted.

The disc 2 is rotatably mounted on the hull about its midpoint, and has one or more hydrofoils 3 arranged eccentrically thereon, spaced apart from the central longitudinal axis of the disc 2, and rotatably mounted about it, And has a streamlined shape.

In an inert working state, the disc 2 is locked, and the hydrofoil 3 is arranged such that when the hydrofoil 3 is at zero position, its longitudinal axis extends parallel to the longitudinal axis of the ship, and the swing angle of the rudder is relative to its proper angle. The swing angle of the rudder is produced by pushing the hydrofoil 3 by the separately arranged drive device 1 .

In the active use state, the disc 2 rotates to generate a thrust, wherein through the control law of the driving device 1, the hydrofoil 3 determines the thrust according to the angle change of the rotation angle of the disc 2, and the thrust direction is 360 degrees The scope is variable. The separate manipulation of the drive means 1 enables the hydrofoil to be varied at any angle while the disc 2 is rotating. Like this, can change thrust according to the rotating speed of aforementioned disk 2, hydrofoil produces idling when zero position, and exceeds zero position and produces reversed thrust. In active use, the unit features adjustable propellers.
