An Adaptive Multifunctional Catamaran Underwater Glider

Abstract

The invention relates to a self-adaptive multifunctional double-body underwater glider, and belongs to the technical field of underwater vehicles. The problems of poor stability, low running speed, low positioning precision and insufficient endurance to maintain large-scale and long-range experiments and researches in the prior art are solved. The self-adaptive multifunctional double-body underwater glider comprises two single glider bodies which are symmetrically arranged with the same structure; each single glider body includes a main glider body, wings symmetrically arranged on the two sides of each main glider body, an attitude adjusting module coaxially arranged in each main glider body, a buoyancy adjusting module coaxially arranged on each main glider body, a temperature differenceenergy driving module arranged on the outer surface of each main glider body and a control module arranged in each main glider body, wherein each attitude adjusting module at least comprises a movablebattery pack which moves along a shaft and rotates around the shaft; the buoyancy adjusting module at least comprises an inner oil bag arranged in each main girder body and an outer oil bag arrangedoutside each main glider body, and the volume of the outer oil bag can be adjusted; and the two adjacent wings of the two single glider bodies are detachably connected through self-spliced wings.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to an adaptive multifunctional catamaran underwater glider. Background technique [0002] The underwater glider belongs to the underwater autonomous vehicle and is a new type of autonomous ocean observation platform. It does not need manual monitoring and control when performing tasks underwater. The difference from ordinary underwater autonomous vehicles is that the underwater glider does not have an external propulsion device. The system is mainly driven by net buoyancy, that is, the cooperative force of gravity and buoyancy. It adjusts the relative position of its center of gravity and buoyancy by moving the weight along the main axis to change the pitch attitude, and swings the tail rudder or rotates the weight relative to the main axis. By changing the rolling attitude, the hydrodynamic components of the fuselage and the fixed tail generate lateral and l...
