Embodiment

[0024] Such as figure 1 Shown is a schematic diagram of the structure of the straight-wing rudder propeller, such as figure 2 Shown is a schematic diagram of the installation position of the straight wing rudder, such as image 3As shown, it is a simplified diagram of the internal structure of the straight-wing rudder. Two straight-wing rudders 600 are installed at the tail of the hull 7. The reduction gear box 2 of the straight-wing rudder 600 is fixedly connected to the hull 7 through the hull installation base 6. The rotary drum 4 is connected to the hull 7. The reduction gearbox 2 is hinged, and the drum 4 rotates clockwise in the figure. The drum 4 establishes a transmission connection with the power input shaft 1 through 12 sets of reduction gears. The middle part of the paddle 5 is hingedly connected with the drum 4. Evenly distributed along the circumference of the drum 4, the top side of the paddle 5 is processed with a slide bar 9, the middle of the drum 4 is hollo...

Abstract

The invention relates to the technical field of ship propellers, in particular to a straight-wing rudder steering control method and system. The straight-wing rudder steering control method comprisesthe following steps that (A) an operating device is selected; (B) skipping to the step (C) when the target navigational speed and the target course are input, and skipping to the step (E) when the propelling direction and the rotational speed are input; (C) the course deviation is calculated, a left correction vector or a right correction vector is selected as a correction vector according to thecourse deviation; (D) a control vector is obtained after the correction vector and a propelling vector are added, the rotational speed and the propelling direction of straight-wing rudders are generated according to the control vector, and skipping to the step (E); (E) when the propelling direction is parallel to the central axis of a hull, the propelling direction zeta is corrected according to the inclination angle theta; and (F) the steps C to F are cycled. The straight-wing rudder steering control method and system have the substantial effects that by detecting the inclination angle of thehull, the propelling direction of a straight-wing rudder propeller on the side with small inclination is corrected according to the inclination angle, thus the difference, generated by inclination, of thrust on the two sides is offset, the influence on the course is avoided, and course stability is improved.

Description

technical field [0001] The invention relates to the technical field of ship propellers, in particular to a straight-wing rudder steering control method and system. Background technique [0002] Straight-wing rudder, also known as straight-wing propeller, is a propulsion tool for ships, suitable for tugboats, ferries, and minesweepers. The straight-wing rudder is mounted on a special flat disc, and several rectangular blades perpendicular to the plane of the flat disc are installed. These blades can not only rotate with the flat disc, but also rotate by themselves through the control mechanism. At a specific position of the disc, the blades themselves rotate along the normal direction of the angular velocity, while at other positions they rotate along the direction of the angular velocity, so that only the blades at the specific position of the blade disc produce greater thrust, while the other positions The blades produce almost no thrust. There is a slide rod on one side ...
