Problems solved by technology

[0006] The current cable-free underwater robot AUV is an underwater autonomous robot that relies on propeller movement, and relies on pre-programmed programs to complete tasks. However, AUVs rely solely on batteries as energy sources, with short working hours and short distances, and are not capable of long voyages. Observation tasks

Abstract

The invention relates to a novel large-span hybrid-driven unmanned underwater vehicle, which comprises a shell structure, a large-span structure, an antenna, a gliding wing, a propeller and a tail fin. The invention is characterized in that: a buoyancy adjusting system, a pitch adjusting system, a control system, a throwing device, a sensor and a communication antenna are arranged in the shell structure; The underwater vehicle can realize the switching of three motion modes according to different tasks and work requirements, and achieve the requirements of saving energy and completing tasks. Mixed gliding and propulsion modes can be used when accelerated diving and descent are required; By controlling the different differential speeds of the two wing-end thrusters, the spatial spiral motion with different radii of gyration can be realized. By adjusting the wing structure and the overall layout of the glider, the anti-disturbance flow performance during gliding is optimized, and the stability of the unmanned aerial vehicle is improved. The underwater vehicle realizes the combination of the advantages of the glider and the AUV, and has the advantages of long range, sufficient space,powerful function, high stability, and strong maneuverability.

Description

technical field [0001] The invention relates to the field of underwater vehicles, in particular to a novel hybrid drive unmanned underwater vehicle with a large wingspan. Background technique [0002] The underwater glider is a new type of unmanned underwater vehicle. It combines the hydrodynamic principle of low energy consumption and long endurance of marine animals with the aerodynamic principle of bird gliding to design an underwater navigation based on unpowered gliding. The method achieves the purpose of low energy consumption, long battery life and simple structure. [0003] In recent years, underwater glider is a new type of underwater vehicle driven by net buoyancy and hydrodynamic force, which has been widely used in the fields of ocean exploration, marine environment investigation, detection and data acquisition. It is favored for its low power consumption, low cost and wide operating range. [0004] The design of traditional underwater gliders generally adopts ...
