Problems solved by technology

There are few research activities on the MHD thruster as an independent propulsion unit. The main reason is that the magnetic fluid thruster is heavy and bulky, and it is not easy to be installed or used independently. The design of the ship body requires the collaborative design of the main engine factory, which has high time and economic costs, and is not easy to carry out practical research on MHD propulsion technology

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, the integrated magnetic fluid propeller of the present invention is a streamlined structure, the left side is the inlet end, which is a hemispherical structure; the middle part is the propeller part, which is a cylindrical shell structure; the right side is the nozzle end, which is A semi-ellipsoidal structure. The integrated magnetic fluid thruster of the present invention is, from left to right, an inlet cavity, an MHD thruster cavity, and an exit cavity. The superconducting magnet 2 and the propulsion channel 5 form the cavity of the MHD thruster, the inlet casing 1, the inlet connecting section 6, and the left load-bearing flange (2-1) of the superconducting magnet 2 are connected in sequence to form the inlet cavity, and the outlet casing 3. The outlet connecting section 4. The right load-bearing flange ...

Abstract

An integrated magnetohydrodynamic drive comprises an inlet shell (1), a superconducting magnet (2), an outlet shell (3), an outlet connecting section (4), a propelling channel (5), an inlet connectingsection (6) and a channel power supply (7). The superconducting magnet, the inlet shell, the propelling channel, the outlet shell, the inlet connecting section and the outlet connecting section formthree independent sealed buoyancy cabins. The drive has the characteristics of relatively simple structure, independent operation and the like, can be used as an independent propelling unit, and can also be externally connected to equipment such as ships and warships to be used as the drive.

Description

technical field [0001] The invention relates to a magnetic fluid thruster. Background technique [0002] Magnetic fluid (MHD) propulsion technology has attracted much attention due to its ultra-quiet effect, but since the efficiency of magnetic fluid is proportional to the square of the magnetic field strength, higher propulsion efficiency requires a higher magnetic field strength; high magnetic fields must use superconducting magnet. At present, all superconducting magnets need to use a cryogenic system, which will inevitably increase the volume and weight of the thruster. Due to the volume and weight of the propeller, the current research on the noise and flow characteristics of ferrofluid propulsion under high field strength is basically carried out through the pipeline platform. There are few research activities on the MHD thruster as an independent propulsion unit. The main reason is that the magnetic fluid thruster is heavy and bulky, and it is not easy to be install...
