A kind of unmanned underwater vehicle and method based on jet steering

Abstract

The invention discloses an unmanned underwater vehicle based on jet steering; an air jet system, a control system, a buoyancy control system and a power supply module are arranged in the outer shell of the aircraft; After the tank passes through the aircraft shell through the air pipeline, a nozzle that provides steering power for the aircraft is formed on the surface of the aircraft shell; the buoyancy control system includes a water tank with a water inlet pipe. The water flow channel between the cabin and the outside of the aircraft shell; the control system includes an air valve for controlling the jet gas flow, a water valve for controlling the water flow in and out, a sensor group for obtaining aircraft operation data, and a control board; the nozzle An air valve is set on the top, and a water valve is set on the water inlet pipe. The sensor group, the air valve and the water valve are all connected to the control board for signals; the sensor group, the air valve, the water valve and the control board are all connected to the power supply module connect.

Description

technical field [0001] The invention relates to an unmanned underwater vehicle, in particular to an unmanned underwater vehicle using jet steering. Background technique [0002] With the development of technology, human beings continue to improve ocean exploration methods. As a favorable tool for ocean exploration, unmanned underwater vehicles have played an important role in both military and civilian applications. In the complex deep-sea environment, there are interference and uncertain factors, which requires strong anti-interference ability for unmanned underwater vehicles. When encountering interference from seawater fluctuations or ocean currents, the unmanned underwater vehicle detects its own attitude changes through sensors and makes timely adjustments to eliminate the interference to ensure that it travels according to the predetermined trajectory; when the interference is large, although the unmanned underwater vehicle It can be adjusted with the help of an advan...

Problems solved by technology

For underwater vehicles driven by rudder propellers, the control ability of rudder blades is related to the speed of the vehicle. At low speeds, the steering sensitivity is low and cannot change direction quickly; for underwater vehicles driven by full propellers, the propellers required The quantity is large, the power consumption is high, and the requirements for the control system are high; the water jet drive is limited by the power of the water pump, and the thrust generated by the water jet is limited, and the underwater vehicle that uses water jet propulsion is difficult because the water flow passes through the interior of the vehicle structure. control its balance
