Abstract

The invention discloses a variable-configuration double-navigation-state long-voyage marine unmanned vehicle driven by natural environment fluid, which has a water surface navigation mode, a navigation switching mode and an underwater navigation mode, and comprises: a wind energy collection unit for receiving aerodynamic force applied by marine wind to drive the vehicle to navigate; a buoyancy adjusting unit which is used for adjusting the buoyancy of the aircraft in an underwater navigation mode and realizing heaving motion and horizontal advancing of the aircraft in combination with hydrodynamic force applied by head-on water flow when the aircraft moves; a wing keel; a linkage unit which is used for completing pose transformation of the sail and the wing keel during sailing mode switching; and a photovoltaic power generation unit which is used for collecting solar energy in a water surface navigation mode and providing electric energy supply for an aircraft power consumption device.According to the variable-configuration double-navigation-state long-voyage marine unmanned aircraft driven by the natural environment fluid, energy self-sufficiency is achieved through sea surface wind and air flow, underwater water flow and sunlight of the natural environment, and the variable-configuration double-navigation-state long-voyage marine unmanned aircraft has the long-distance navigation capacity under the water surface navigation state and the underwater navigation state.

Description

technical field [0001] The invention relates to the technical field of new marine unmanned aerial vehicles, in particular to a variable-configuration dual-navigation long-range marine unmanned aerial vehicle driven by natural environment fluids. Background technique [0002] Marine unmanned aerial vehicle refers to an unmanned system navigating in the ocean, and it is an important tool for modern ocean observation and detection. According to the navigation space, it is usually divided into two types: surface unmanned aerial vehicles (unmanned ships) and underwater unmanned aerial vehicles (unmanned submersibles). Surface navigation and underwater navigation are two different navigation states. In order to adapt to different navigation spaces and navigation states, existing surface unmanned aerial vehicles are mostly developed and built based on the technical system of small ships. Existing underwater unmanned navigation Most of the devices are developed and built based on t...
