Electromagnetic energy-saving drag reduction device for unmanned underwater vehicle

Abstract

The invention discloses an electromagnetic energy-saving drag reduction device for an unmanned underwater vehicle. The device comprises a power generation module and an electromagnetic drag reductionmodule. The power generation module comprises a generator impeller, a generator impeller fixing support and transmission mechanism and a generator set. The generator impeller is arranged on the outerside of a propeller, the generator impeller fixing support plays a fixing role, the transmission mechanism is connected with one side of the impeller and the generator set, and the generator set is connected with an electric energy output end. The generator impeller is composed of a plurality of impellers, so that residual energy is convenient to collect. The generator set provides electric energyfor the electromagnetic drag reduction module; the electromagnetic control module comprises thin strip-shaped magnets, thin strip-shaped electrodes, a fixing frame and a rechargeable battery, the overall shape of the module is consistent with the shape of an airfoil and is tightly attached to the airfoil of the unmanned underwater vehicle, an electromagnetic activation plate is composed of strip-shaped magnets and strip-shaped electrodes which are arranged at intervals, the polarities of the tops of every two adjacent strip-shaped magnets are opposite, and the polarities of every two adjacentstrip-shaped electrodes are opposite. The thickness of the electrode is equal to that of the magnet, and the electrode and the magnet are fixed and connected through the fixing outer frame. And the electrode magnetic poles are arranged in parallel along the flow direction. The device provides electric energy for the electromagnetic drag reduction module, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The present invention belongs to the field of drag reduction of flying bodies, in particular to an electromagnetic energy-saving drag reduction device for unmanned underwater vehicles. Background technique [0002] Unmanned submersibles generally refer to devices under the water surface that can navigate underwater by remote control or automatic control. Unmanned submersibles can be used for various tasks such as marine reconnaissance, anti-submarine warfare, and mines. Many unmanned submersibles adopt a hull + wing layout, which looks like a small plane, so unmanned submersibles are also called underwater gliders. [0003] Underwater power is currently one of the most effective means to collect intelligence and implement power projection in the "anti-access / area denial" environment. Major military powers are trying to build or maintain underwater advantages by vigorously developing underwater unmanned equipment with autonomous submersibles as the mai...
