Abstract

The invention belongs to the technical field of ship engineering and fluid mechanics, and particularly relates to a propeller turbocharging device. Comprising a ship body, a steering rudder driving rod is installed on the ship body, a steering rudder is fixedly installed at the lower end of the steering rudder driving rod, a support and a propeller assembly are further installed on the ship body, a fairing assembly is installed on the support, and one side of the propeller assembly is located in the fairing assembly. The propeller blade hub is driven to rotate through the propeller blade transmission shaft, the propeller blades are driven to rotate through the propeller blade hub, water flow is driven to flow through the propeller blades, and then the ship body is pushed to move forwards through the counter-acting force of the water flow. Tangential and radial velocity components in the wake flow of the propeller are extracted through a turbine area and turbine blades, and the energy is applied to increase of the water inlet pressure of the propeller. The turbine area can be driven by the wake flow area to actively provide kinetic energy and increase the water pressure at the front end of the propeller; and the direction of the ship body can be controlled through the steering rudder.

Description

technical field [0001] The invention belongs to the technical fields of ship engineering and fluid mechanics, and in particular relates to a propeller turbocharging device. Background technique [0002] The ocean development technology and equipment presented by the development of ocean engineering and science and technology in the world continue to improve, promoting the comprehensive development and utilization of ocean resources, and the development and utilization of ocean energy has become an important pillar for the development of ocean countries. [0003] A ship is composed of many parts. According to the function and use of each part, it can be comprehensively summarized into three parts: hull, ship power plant, and ship electrical. The hull is the basic part of the ship, which can be divided into the main part and the superstructure part. The main part generally refers to the part below the upper deck. It is a hollow body with a specific shape surrounded by the hul...
