Underwater glider open-loop active flow control device based on steady jet

Abstract

The invention discloses an underwater glider open-loop active flow control device based on steady jet and relates to the field of active flow control. The device comprises a miniature water spray pumpset arranged at the rear end below wings of an underwater glider; the miniature water spray pump set is communicated with a water storage bin; the bottom of the water storage bin is communicated witha miniature submersible pump; and the miniature submersible pump and the miniature water spray pump set are respectively connected with a control unit. The miniature water spray pump set is connectedwith a fixed nozzle, the end of the fixed nozzle is communicated with a steady jet opening, and the steady jet opening is formed in the rear end of the upper surface of the underwater glider wing. Local disturbance in a steady jet mode is achieved through the miniature water spray pump set, and then active flow control is completed.

Description

technical field [0001] The invention relates to the technical field of active flow control, in particular to an open-loop active flow control device for an underwater glider based on a steady jet. Background technique [0002] Underwater Glider (UG) is a new type of underwater vehicle that uses net buoyancy and attitude angle adjustment to obtain propulsion. Compared with traditional underwater vehicles, underwater glider has the advantages of long range, strong continuous working ability and good economy. As an underwater unmanned intelligent mobile platform, underwater glider has broad application prospects and great potential value in the fields of exploring marine resources, marine scientific investigation and military affairs. According to the appearance, underwater gliders can be divided into two types: traditional rotary type and wing-body fusion type. Since the shape of the rotor shell cannot provide very high lift like hydrofoils, the maximum lift-to-drag ratio of...

AI Technical Summary

Problems solved by technology

At present, the lift-to-drag ratio of wing-body fused underwater gliders can reach 15-20 through shape optimization. Further improvement of the lift-to-drag ratio

Moreover, only relying on shape optimization to increase the lift-to-drag ratio of an underwater glider will narrow the internal space of the glider, reducing its detection capability or working time.
