Water surface single-body unmanned wing skid with dual water jet propulsion

Abstract

The invention discloses a water surface monomer unmanned wing slip boat with double water jet propellers. The bilge part of the hull at the front of the midship of the main hull has a composite hydrofoil with double flared airfoil columns, and the double outwardly flared airfoil columns The composite hydrofoil is composed of two variable-section cylindrical appendages and two wings. The tops of the two variable-section cylindrical appendages are seamlessly connected with the hull, and the bottom of one variable-section cylindrical appendage is fixedly connected to a hull. Wing, the included angle between the two wings and the horizontal plane is 25-45°; a water inlet connected with the water outlet is opened at the front part of each wing; The nozzle descends to the bottom wing, which can not only provide forward thrust to make the ship move forward, but also provide vertical upward additional lift, so that the front of the hull can be lifted, so that the ship can slide better. The water inlet and the sliding surface The distance is widened, which is conducive to the reduction of resistance, and greatly improves the gliding efficiency and the speed of the boat.

Description

technical field [0001] The invention relates to a ship, in particular to a water surface single unmanned wing skid boat with double water jet propellers which is used 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-body unmanned boat, it is generally in a semi-planing or fully gliding state when sailing. In this way, the sliding surface is destroyed, the resistance is increased, and the gliding efficiency and rapidity of the boat are greatly reduced. Contents of the inven...
