A multi-helical channel annular superconducting magnetic fluid propeller

Abstract

The invention provides a multi-spiral-channel annular superconducting magnetic fluid propeller. A plurality of tangential-feeding and tangential-discharging single-spiral-channel superconducting magnetic fluid propelling units (1) are layered in the longitudinal direction of an underwater vehicle housing (4) and are uniformly distributed on the outer surface or the inner surface of the underwatervehicle housing (4) in the circumferential direction of the underwater vehicle housing (4). Each single-spiral-channel superconducting magnetic fluid propelling unit (1) comprises a spiral tube superconducting magnet (1-1) and a tangential-feeding and tangential-discharging spiral channel (1-2), and is connected with a water inlet pipe (2) and a water outlet pipe (3); and seawater flows into the spiral channels (1-2) in the tangential direction of the water inlet pipe (2), and flows out of the spiral channels (1-2) in the tangential direction of the water outlet pipe (3). The spiral tube superconducting magnets (1-1) of the superconducting magnetic fluid propelling unit (1) on all layers are distributed uniformly in the circumferential direction to form a closed magnetic circuit, and magnetic lines are closed in the single-spiral-channel superconducting magnetic fluid propelling units on all the layers.

technical field [0001] The invention relates to a superconducting magnetic fluid propeller. Background technique [0002] The helical channel superconducting ferrofluid thruster uses a helical tube superconducting magnet and a helical channel. The helical tube superconducting magnet can realize a high magnetic field in a large magnetic field space. The helical channel increases the effective length of the electromagnetic force, thereby improving the propulsion efficiency and Thrust density is currently the most researched and the closest to practical ferrofluid propulsion. [0003] figure 1 It is a traditional axial-in-axial-out single-helical channel superconducting magnetic fluid propeller, which is mainly composed of a spiral tube superconducting magnet and an axial-in-axial-out helical channel, and an axial-in-axial-out helical channel Horizontal through the magnetic hole of the solenoid superconducting magnet.

image 3 The arrangement of the multi-helical channel superconducting ferrofluid propeller shown in the figure takes up a huge space, and its inlet 2 and outlet 3 must be parallel to the direction of travel of the ship, that is, the longitudinal direction of the hull, which is not conducive to the coordinated arrangement of the propeller and the hull.

[0005] Additionally, for figure 1 and image 3 In the single helical channel shown axially in-axially out, the electromagnetic force is in the circumferential direction, that is, the seawater flows helically along the helical blade in the area where the electromagnetic force acts, and the seawater enters axially and flows out of the helical channel axially. Under the action of deflectors and rectifiers, the smooth transformation between axial flow and helical flow can be carried out, and the local resistance loss can be greatly reduced. However, deflectors and rectifiers have three-dimensional spatial structures and complex structures. The flow area where deflectors and rectifiers are located The local resistance loss of the
