Controlled hydrofoil hydroplane and control method thereof

Abstract

The invention discloses a controlled hydrofoil hydroplane and a control method thereof. A groove rail is arranged on each of shipboards at two sides, a hydraulic transmission device is arranged in the groove rails, and the top end of a hydraulic push rod is fixedly connected with a hydrofoil system; a water sealing case is located in the groove rails and can slide to and fro along the longitudinal direction, and the top end of the hydraulic push rod is fixedly connected with the water sealing case; an electromotor is arranged in the water sealing case, and the output shaft of the electromotor is vertical to the shipboards, extends out of the groove rails and is fixedly connected with a hydrofoil; and a central processing unit sends a command to control the electromotor to drive the hydrofoil to rotate to an optimal variable attack angle alpha with the horizontal plane, and to control the hydraulic control system to drive the hydraulic push rod to push the hydrofoil to move so as to obtain moment, so that the heaving, pitching, rolling, swing, revolution, jerking, slowing and the like of the hydroplane can be controlled at high precision, and the seagoing performance is improved.

Description

technical field [0001] The invention belongs to the technical field of boat manufacturing, in particular to a hydrofoil planing boat. Background technique [0002] Planing boats have excellent hydrodynamic properties and are widely used in small boats, such as patrol boats, fishing boats, service boats, ambulance boats and sports boats. When the planing boat is in the gliding state, the structure at the bottom of the stern of the gliding boat serves as the main gliding surface to provide dynamic lift, lift the hull to reduce the wet surface area, reduce frictional resistance, and increase the speed accordingly. Therefore, many planing boats add appendages to the rear part to increase the sliding surface and increase the dynamic lift. Due to the lifting of the hull, the contact area between the hull of the planing boat and the water surface becomes smaller, resulting in poor seaworthiness of the planing boat. [0003] In order to improve the sailing performance of the plani...

AI Technical Summary

Problems solved by technology

The above three disclosed technologies can only improve one or several of the performance of the planing boat, and the added peripheral equipment is fixed, which cannot realize the control of the hull motion attitude, and its control range and control accuracy are limited
