A wing-changing mechanism of an underwater glider

Abstract

The invention discloses a novel underwater glider wing changing mechanism. The novel underwater glider wing changing mechanism comprises wings and a transmission system. The transmission system is composed of a planar parallel mechanism and motor assemblies. The wings include the fixed wing and the movable wing. The fixed wing and the movable wing are connected through the planar parallel mechanism. Two dovetail guide rails are arranged on the fixed wing in parallel. Dovetail sliding blocks are arranged in the dovetail guide rails respectively. Two connection points used for connecting the motor assemblies are further arranged on the fixed wing. The planar parallel mechanism is composed of a first crank, a first connecting rod, one dovetail sliding block, a second connecting rod, an output rod, one dovetail sliding block, a third connecting rod and a second crank which are sequentially hinged to one another between the two connection points. The output rod is connected with the movable wing through a screw. The novel underwater glider wing changing mechanism is high in practicality and reliable in function, the span-chord ratio and sweepback of the wings of an underwater glider can be adjusted according to task requirements, and the navigational performance is improved.

Description

technical field [0001] The invention relates to an underwater glider wing-changing scheme, and more specifically relates to a wing-changing mechanism of an underwater glider. Background technique [0002] As a brand-new ocean monitoring equipment, the underwater glider has the following working principle: generate heave motion by changing the buoyancy, generate lift through the wings on both sides, adjust the attitude by changing the center of gravity of the glider, and finally realize the zigzag gliding motion. The wing parameters of the underwater glider have an important influence on the navigation performance of the underwater glider, and the wing parameters mainly include the aspect ratio and the sweep angle. The wing aspect ratio mainly affects the navigation economy. The larger the wing aspect ratio is, the higher the navigation economy is. The wing sweep angle mainly affects the navigation stability. When the sweep angle changes within a certain range, the higher the...

Problems solved by technology

However, most current underwater gliders use fixed wings. Therefore, during a navigation mission, the underwater glider cannot adjust the shape of the wing according to the mission requirements to change the navigation performance of the underwater glider.
