Wake regulation device for underwater vehicle

Abstract

The invention discloses a wake regulating device of an underwater vehicle and a regulating method thereof. The wake regulating device of the underwater vehicle comprises a centrifugal pump, a drainage pipe, a deflector, a support plate, a nozzle pipe, an electromagnetic control nozzle and Electromagnetic injection controller. The wake regulating device of the underwater vehicle adjusts the non-uniformity of the wake field through the shape structure of the shroud and the support plate, and at the same time, it can also realize real-time The electromagnetic control nozzle is adjusted and controlled to realize the adjustment of the flow rate, flow velocity and direction of the water flow from the electromagnetic control nozzle, thereby changing the non-uniformity of the wake field of the underwater vehicle. The underwater vehicle wake regulating device of the present invention realizes the real-time and accurate control of the vehicle wake field by means of the central controller that comes with the vehicle, ensures the propulsion efficiency of the propeller propeller, and makes the vehicle smooth sailing.

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
