Unmanned underwater vehicle based on gas jet steering and method thereof

Abstract

The invention discloses an unmanned underwater vehicle based on gas jet steering. A gas jet system, a control system, a buoyancy control system and a power module are arranged in a vehicle housing; the gas jet system comprises a gas storage tank with a gas charging port, the gas storage tank penetrates through the vehicle housing by virtue of a gas transporting pipeline, and a nozzle for providing the vehicle with steering power is formed on the surface of the vehicle housing; the buoyancy control system comprises a water chamber with a water inlet pipe, wherein the water inlet pipe penetrates through the vehicle housing to form a water flow channel between the water chamber and the exterior of the vehicle housing; the control system comprises a gas valve for controlling the flow rate of a jet gas, a water valve for controlling water flow to go in and out, a sensor group for obtaining the operation data of the vehicle, and a control mainboard; the gas valve is arranged on the nozzle, the water valve is arranged on the water inlet pipe, and the sensor group, the gas valve and the water valve are all in signal connection with the control mainboard; the sensor group, the gas valve, the water valve and the control mainboard are all electrically connected with the power module.

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...

AI Technical Summary

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
