A dual-function deep-sea unmanned submersible with variable wing shape and its working method

Abstract

The invention discloses a variable wing shape dual-function deep-sea unmanned vehicle and a working method thereof, which relates to the field of underwater vehicles. The variable wing shape dual-function deep-sea unmanned vehicle comprises a variable wing system, a retractable propulsion system and a distributed pressure-resistant system. The retractable propulsion system includes a retractable propulsion vehicle located at the after portion of the submersible vehicle. Distributed withstand pressure system includes withstand pressure battery cabin, main withstand pressure electronic cabin, hydrodynamic light shell, head and tail residual buoyancy device. The variable wing system consists of front and rear main wings and spokes. The main wings and spokes are symmetrically distributed alongthe axial direction of the airframe. The main wings are designed with high aspect ratio contractible mechanism. The spoke includes a movable rudder. The problems of drag and dynamic instability are solved, and the two modes of large-scale gliding and high-speed direct navigation are fused.

Description

technical field [0001] The invention relates to the field of underwater vehicles, in particular to a variable-wing dual-function deep-sea unmanned submersible and a working method thereof. Background technique [0002] In the current unmanned underwater vehicle technology, the underwater glider is suitable for performing long-term and large-scale marine environment detection and monitoring operations due to its unique low-speed gliding advantages of low power consumption and long range. It can only perform zigzag gliding at low speed in water bodies. [0003] Generally, propellers can be added to enable the underwater glider to perform both "zigzag" gliding motion and linear motion, but in this way, the propellers equipped with "zigzag" gliding motion will have a negative impact on the gliding motion. Motion produces greater resistance, which affects the speed of gliding and the distance of gliding. When performing linear motion, the hang glider used for gliding motion will...

[0002] In the current unmanned underwater vehicle technology, the underwater glider is suitable for performing long-term and large-scale marine environment detection and monitoring operations due to its unique low-speed gliding advantages of low power consumption and long range. It can only perform zigzag gliding at low speed in water bodies

[0003] Generally, propellers can be added to enable the underwater glider to perform both "zigzag" gliding motion and linear motion, but in this way, the propellers equipped with "zigzag" gliding motion will have a negative impact on the gliding motion. Motion produces greater resistance, which affects the speed of gliding and the distance of gliding. When performing linear motion, the hang glider used for gliding motion will generate greater resistance to linear motion and instability. In addition, due to the increase of the propeller It will lead to a more bloated design of the submarine, and there will not be enough space for other detection sensors
