Small water plane and semi-submersible composite unmanned surface vehicle

Abstract

The invention discloses a small water plane and semi-submersible composite unmanned surface vehicle which comprises a submerged body, a supporting body, a surface floating body and a propelling device, wherein the supporting body is vertically arranged in the middle of the submerged body; the surface floating body is fixedly supported at the top of the supporting body; and the propelling device is arranged at the stem part of the submerged body; a liftable sensing platform is embedded in the top of the surface floating body; hydrofoils in three layers are symmetrically arranged on two sides of the supporting body from top to bottom; the hydrofoil in the upper layer is arranged below the surface floating body; the hydrofoil in the middle layer is arranged below the hydrofoil in the upper layer; and the hydrofoil in the lower layer is horizontally arranged on the lower side of the supporting body. The small water plane and semi-submersible composite unmanned surface vehicle disclosed by the invention has the advantages as follows: the overall performance of the composite unmanned surface vehicle is superior to those of a single-hull planing boat and a traditional three-hull unmanned surface vehicle; particularly, the swaying motion performance is greatly improved; the seaworthiness of the composite unmanned surface vehicle is more than 60 % higher than those of the single-hull planing boat and the traditional three-hull unmanned surface vehicle, so that the condition that a small-sized unmanned vehicle normally works in a terrible ocean environment becomes possible.

Description

technical field [0001] The invention relates to an unmanned boat, in particular to a small water plane area semi-submersible composite surface unmanned boat used for water monitoring, and belongs to the technical field of high-performance ships. Background technique [0002] The surface unmanned vehicle is an intelligent unmanned platform that can perform various military and civilian tasks in complex ocean environments. Because of its small size and good invisibility, it has been valued and developed by countries all over the world in recent years. At present, domestic unmanned boats generally use single-body planing boats or conventional trimaran-type unmanned boats. Single-body planing boats and conventional trimaran-type unmanned boats have small displacement and poor stability during static floating or high-speed navigation (especially swaying). Movement), it is difficult to work normally under high sea conditions, which greatly affects its seaworthiness and poor naviga...

Problems solved by technology

At present, domestic unmanned boats generally use single-body gliding boats or conventional trimaran-type unmanned boats. Single-body gliding boats and conventional trimaran-type unmanned boats have small displacement and poor stability during static floating or high-speed navigation (especially swaying). movement), it is difficult to work normally under high sea conditions, which greatly affects its seaworthiness, and the navigation economy is poor
