Wake flow adjusting device of underwater vehicle

Abstract

The invention discloses an underwater vehicle wake flow adjusting device and an adjusting method thereof. The underwater vehicle wake flow adjusting device comprises a centrifugal pump, a drainage pipe, a flow guide cover, a supporting plate, a spraying pipe, an electromagnetic control nozzle and an electromagnetic spraying controller. The wake flow adjusting device is advantaged in that non-uniformity of a wake flow field is adjusted through appearance structures of the flow guide cover and the supporting plate, in addition, the electromagnetic control nozzle can be adjusted and controlled inreal time according to the wake flow field information collected by a central controller of the underwater vehicle, adjustment of the flow, the flow speed and the direction of outlet water flow of the electromagnetic control nozzle is achieved, and then non-uniformity of the wake flow field of the underwater vehicle is changed. The wake flow adjusting device of the underwater vehicle is advantaged in that by means of a central controller of the vehicle, the wake flow field of the vehicle is accurately adjusted and controlled in real time, propelling efficiency of the propeller thruster is guaranteed, and the vehicle can smoothly sail underwater.

Description

technical field [0001] The invention belongs to the technical field of ships and ocean engineering, and in particular relates to a wake regulating device for an underwater vehicle. Background technique [0002] An underwater vehicle is a vehicle that sails underwater, including manned underwater vehicles and unmanned underwater vehicles. With the help of underwater vehicles, underwater exploration, detection, and even military offensive and defensive etc. It can be seen that underwater vehicles play an important role in both civilian and military fields. As ocean development becomes more and more important today, various countries pay more and more attention to the development and improvement of underwater vehicles. [0003] When navigating in water, the conical shell at the stern of the underwater vehicle and the cylindrical shell on the hull will cause strong distortion of the wake flow field of the vehicle, and the propeller propeller will generate strong axial thrust vi...

AI Technical Summary

Problems solved by technology

[0004] Existing wake regulation devices for underwater vehicles are generally passive vane-type fairings. The blades are fixed on the inner wall of the fairing and the stern conical shell, which cannot actively change the non-uniformity of the flow field, and cannot timely adjust the propeller. The velocity, flow and direction of the incoming flow in front of the paddle disk have very limited effects on the vibration and noise reduction of underwater vehicles
