An active flow control system for a wing-body fusion underwater glider

Abstract

The invention discloses an active flow control system for wing-body fusion underwater glider, which relates to the field of flow control, including an electromagnetic flow control actuator unit installed on the front end of the upper surface of the wing of the underwater glider, and an The position where the electromagnetic flow control actuator unit is installed on the surface is alternately provided with a steady jet port and a synthetic jet port; a steady jet flow control actuator unit is provided below the steady jet port, and a synthetic jet port is provided below the synthetic jet port. The flow control actuator unit; the electromagnetic flow control actuator unit, the steady jet flow control actuator unit and the synthetic jet flow control actuator unit are respectively connected with the signal processing and control system, and the signal processing and control system is connected with sensors, The sensor is fixedly arranged on the wing of the underwater glider. The invention can realize the flow control objectives of different parts on the underwater glider under different flow control strategies.

Description

technical field [0001] The invention relates to the field of active flow control, in particular to an active flow control system for a wing-body fusion underwater glider. 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 traditional rotor gliders...

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.
