A flexible tail structure and underwater vehicle

Abstract

The invention relates to the technical field of underwater vehicles, and discloses a flexible tail structure and an underwater vehicle, including a tail boom, a tail wire, an air tank, an air bag and an antenna. A tail wire is connected to the tail rod, and the tail wire is bendable The end of the tail wire away from the tail rod is connected to the air tank, the antenna is arranged in the air bag, the air bag and the air tank are connected, and the tail wire communicates with the antenna to transmit signals. When the underwater vehicle sinks underwater, the flexible tail structure is subjected to the resistance of the water when the underwater vehicle sails, and the tail line is straightened. When the underwater vehicle deviates from the predetermined direction, the air tank and the air bag are pulled by the tail line The tail boom applies a restoring moment to the aircraft body through the tail boom, which simplifies the structure of the tail and improves the stability of the underwater navigation of the aircraft; The role of the device is very small, the airbag is exposed to the water surface, and the antenna located in the airbag is exposed to the water surface with the airbag, which ensures the communication quality.

Description

technical field [0001] The invention relates to the technical field of underwater vehicles, in particular to a flexible tail structure and an underwater vehicle. Background technique [0002] Underwater glider is a new type of underwater robot, which uses net buoyancy and attitude angle adjustment to obtain propulsion, consumes very little energy, only consumes a small amount of energy when adjusting net buoyancy and attitude angle, and has high efficiency and long endurance. It has the characteristics of low manufacturing cost and maintenance cost, reusable, and large-scale delivery, and is widely used in large-scale ocean exploration. [0003] In order to improve the directional stability of the vehicle during movement, the water tank vehicle generally needs to be equipped with a vertical tail and a horizontal tail in the design, so that the underwater vehicle can sail stably along a given direction, reduce the frequency of directional control, reduce energy consumption, a...
