The invention discloses an underwater vehicle microbubble drag reduction device and a control system, and relates to the technical field of underwater vehicles, the underwater vehicle microbubble drag reduction device comprises a liquid gas evaporation box and a gas diversion bin, the liquid gas evaporation box and the gas diversion bin are both installed in an underwater vehicle, and a heating plate is arranged at the bottom of the liquid gas evaporation box; the top of the liquid gas evaporation box is connected with a third flexible gas conveying pipe, one end of the third flexible gas conveying pipe is connected with a fourth flexible gas conveying pipe, the fourth flexible gas conveying pipe is installed on a gas distribution bin, pressure dynamic feedback control is achieved through a single-chip microcomputer, and gas generation in the system is controlled through heating and gasification of a hydraulic box. The device is simple in structure, efficient and energy-saving, a multi-section multi-nozzle air injection mode is adopted, the bubble coverage area large enough is formed around the underwater vehicle, the fine bubble stone with the smaller hole diameter is adopted to improve the flow speed of water at the air release structure, and the drag reduction purpose is achieved. And a solution is provided for reducing the resistance of the underwater vehicle in the diving process and accelerating diving.
