Flying airfoil towfish driven by ocean currents

Abstract

The invention belongs to the technical field of underwater robots, and particularly relates to a flying airfoil towfish driven by ocean currents. In the absence of a buoyancy adjusting device, an anchoring base and an anchor chain are fixed in a certain area, the lifting action force of the ocean currents is changed by adjusting the attack angle between a wing body and the ocean currents, and three different motion effects of floating up, diving down and suspension are realized. The flying airfoil towfish driven by the ocean currents does not rely on a water surface communication buoy, can emerge from the water periodically and uses a hydrofoil antenna mast for communication and data transmission. A flow guide housing in a blended wing body form is adopted, the lift-drag ratio of the flying airfoil towfish can be greatly improved, and it is ensured that the flying airfoil towfish can still operate normally under the condition of small ocean currents. Meanwhile, the flying airfoil housing provides a large volume space and can carry more mission sensors to meet different mission requirements. The flying airfoil towfish driven by ocean currents has the characteristics of low energy consumption, large effective payloads, high security and good concealment, and can be used for monitoring the ocean environment in the area for a long time.

Description

technical field [0001] The invention belongs to the technical field of underwater robots, and in particular relates to a flying wing-type towfish driven by ocean currents. Background technique [0002] In recent years, underwater robots have great application value in civilian fields such as marine environment research, marine resource detection and submarine reconnaissance, and have attracted widespread attention of scientific researchers. An underwater glider is a special kind of underwater robot. It realizes gliding motion by adjusting the difference between its own gravity and buoyancy and its motion attitude. It has many advantages that intelligent underwater robots do not have, such as long range, flexibility and low cost. It has been widely used in the collection of marine data, and it can measure different marine environmental parameters by carrying different sensors. However, due to poor maneuverability, it is difficult for underwater gliders to eliminate the inte...

However, under the influence of ocean currents, the ability of its profile movement will be greatly limited

At the same time, the adjustment method of profile movement consumes a lot of energy, and the energy system it carries is difficult to meet the requirements of ultra-long working hours
