Speedboat veneer double acting rectifying anti-drag stabilizer

Abstract

The invention discloses a single-plate double-action rectifying-stabilizing device for yachts, comprising two driving mechanisms and an executing mechanism. The driving mechanisms are respectively arranged on the upper parts of two sides in a stern of a yacht; the executing mechanism is arranged outside the yacht; stepping motor shafts of the driving mechanisms are connected with a drive shaft; eccentric wheels are arranged in oil-bearing drive sliders; a base plate is fixed outside a stern sealing plate; a rectifying plate is arranged between the base plate and a cover plate; two oil-bearingdrive sliders support the rectifying plate; and an oil-bearing guiding slider guides the rectifying plate. Through the different combined rotation of the two driving mechanisms, the device drives therectifying plate to make different combined movements so as to allow the lower edge of the rectifying plate to cut into water, which changes the water flow field under the yacht as well as the hydrodynamic pressure center, so as to reduce swing and resistance. The device only adds few components to the stern of the yacht, which not only solves the problem that a yacht body produces great swing ina sailing process, but also reduces the resistance for the yacht in various sailing states through the water cutting movement of the rectifying plate.

Description

technical field [0001] The invention relates to a drag and roll reduction device for speedboats, in particular to a drag and roll reduction device with an adjustable fairing plate. The invention is suitable for single-hull and double-hull speedboats with flat stern sealing plates, and belongs to the technical field of ships. Background technique [0002] Speedboats (referring to displacement boats, transition boats and planing boats with a volume of more than about 1.0), when the speedboat is sailing at high speed on the water surface, due to the action of wind and waves, the single-body speedboat will produce a large roll and a large heave The catamaran speedboat will produce a relatively large pitch and heave motion, which poses a threat to the safety of personnel, equipment and boats, especially for military boats, it will make weapons unable to use normally, and even delay fighter planes. The traditional ship anti-rolling devices mainly include the following: bilge keel...

AI Technical Summary

Problems solved by technology

The adjustable wave breaker adapts to a wider speed range of the speedboat, but when the speedboat sails at a lower speed, it will still increase the resistance of the speedboat
