Water-surface single-body unmanned boat of single-water-spraying propeller

Abstract

The invention discloses a water-surface single-body unmanned boat of a single-water-spraying propeller. A composite stabilization fin is connected under the middle of a boat stern and is composed of an appendage and a wing. The appendage is symmetrical about a boat bottom in a left-and-right mode and perpendicular to the boat bottom, and the upper end of the appendage is seamlessly connected with the boat bottom. The lower end of the appendage is fixedly connected with the wing which is horizontally arranged, and the wing is symmetric about the appendage in a left-and-right mode. Water inlet channels are formed in the wings and the appendage, and water inlets of the water inlet channels are formed in the front portion of the bottom of the wing and communicated with a water outlet through the water inlet channels. Due to the action of the wing, additional lift force is generated, the sliding efficiency is further improved, the composite stabilization fin facilitates the shipping-direction stability, the roll amplitude reduction and the like of the boat, the defect that an existing water-surface unmanned sliding boat based on water spraying propelling is low in sliding efficiency is effectively overcome, due to rapidity, the water-surface single-body unmanned boat of the single-water-spraying propeller is superior to the existing water-surface unmanned sliding boat based on water spraying propelling, and the shipping-direction stability and seaworthiness are obviously improved.

Description

technical field [0001] The invention relates to a ship, in particular to a water surface single-body unmanned boat with a single water jet propeller for dynamic monitoring of various operations on the water surface. Background technique [0002] At present, surface unmanned boats generally adopt a single-body type. Due to the small displacement and size of the boat type, it is particularly sensitive to the external wind, waves, and current environment, and has a large range of swaying motion in wind and waves. In order to maintain a relatively stable speed, for displacement boats, water jet propellers are generally installed at the bottom of the hull. Due to the small tonnage of the surface single unmanned boat, it is generally in a semi-planing or fully gliding state when sailing. At this time, simply install a water jet propeller directly on the original semi-planing or gliding hull itself, and the water inlet is on the gliding surface. On the surface, the sliding surface...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems of gliding efficiency and rapidity of existing single water surface unmanned boats, and provide a water surface single unmanned boat with composite stabilizing fins at the bottom of the tail hull of a single water jet propeller. The nozzle is under the sliding surface, which has excellent fast characteristics
