Abstract

The invention discloses a marine rudder equipped with a spoiler, which comprises a rudder blade, a first spoiler and a second spoiler; a hydraulic drive system is arranged inside the rudder blade, and the hydraulic drive system includes a first hydraulic chamber, a second Hydraulic chamber and hydraulic pump; the first spoiler is provided with a first drive member, the first drive member includes a first drive plate, the first drive plate is arranged in the first hydraulic chamber, and the two ends of the first hydraulic chamber are provided with driving hydraulic pressure The hydraulic pump drives the first drive plate to move in the first hydraulic chamber by driving the hydraulic pipe; the two ends of the second hydraulic chamber communicate with the two ends of the first hydraulic chamber respectively through the balance hydraulic pipe. The invention discloses a marine rudder equipped with a spoiler. Spoilers are respectively arranged on the two rudder surfaces at the tail of the rudder, and the spoiler is rotated by a hydraulic drive system. When the rudder is steered, the two spoilers are opened. , to form a fishtail rudder shape to obtain higher rudder efficiency. When sailing straight or reversing, close the spoiler to form a streamlined rudder shape to reduce the resistance of the rudder.

Description

technical field [0001] The invention relates to the field of marine rudders, in particular to a marine rudder equipped with a spoiler. Background technique [0002] Ships are mainly equipped with rudders at the stern to achieve heading stability and slewability, and the performance of the rudder itself has a significant impact on the ship's maneuverability. In order to improve the rudder efficiency, people have successively proposed a series of special rudder types, among which the rudder effect of the fishtail rudder is particularly prominent. The cross-sectional shape of the fishtail rudder is like a flat fish, and the shape of the fishtail rudder is more than that of the streamlined rudder. [0003] When the fishtail rudder is in the steering state, the water pressure on the upstream surface of the rear of the rudder blade increases, which significantly improves the rudder efficiency. Direct flight or reverse performance is significantly reduced. SUMMARY OF THE INVENT...
