U-shaped circulation convection flap propulsion device

Abstract

The invention relates to a U-shaped circulation convection flap propulsion device, which includes a circulation pipeline with an integral hollow structure, the openings at both ends of the circulation pipeline are arranged at relative intervals; a wing plate is installed in the interval between the openings at both ends of the circulation pipeline, An adjustment seat is installed at the end of the wing plate, and the axial direction of the wing plate swinging with the adjustment seat is perpendicular to the connection line between the openings at both ends of the circulation pipeline; one or more sets of axial flow pumps are arranged inside the circulation pipeline along the axial direction, and the circulation The openings at both ends of the pipeline are the inlet and outlet respectively. Under the action of the axial flow pump, the fluid enters from the inlet of the circulation pipeline, flows out from the outlet and passes through the wing plate and then enters the inlet to form a cycle. The fluid generates thrust on the wing plate, so that most of the fluid circulates in the pipeline to generate thrust, while effectively suppressing the generation of the wake characteristics of the existing propeller, and greatly assisting the low-noise and quiet operation of the propulsion device.

Description

technical field [0001] The invention relates to the technical field of underwater navigation propellers, in particular to a U-shaped circulation convection vane propulsion device. Background technique [0002] In the prior art, a ship or an underwater vehicle mainly converts mechanical energy into kinetic energy for the ship to advance through a rotating part—the propeller. force. [0003] The propeller propeller has the advantage of high propulsion efficiency, but it has inherent deficiencies in the control of vibration, noise, and cavitation. In water, it is easy to cause vibration, noise and cavitation problems; in addition, during the rotation of the propeller, a part of the energy will inevitably be brought into the wake. The strength of the trailing target is not conducive to its target concealment. Contents of the invention [0004] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provides a U-shaped circulation conv...

[0003] The propeller propeller has the advantage of high propulsion efficiency, but it has inherent deficiencies in the control of vibration, noise, and cavitation. In water, it is easy to cause vibration, noise and cavitation problems; in addition, during the rotation of the propeller, a part of the energy will inevitably be brought into the wake, such as cavitation on the surface of the blade, which is easy to transmit the air bubbles to the far rear, increasing the The strength of the trailing target is not conducive to its target concealment
