Embodiment 1

[0022] Example 1: Permanent Magnetic Magnetic Suspension Rotor Structure

[0023] exist Figure 4 In the shown first embodiment of the present invention, the magnetic levitation ring 9 on the rotor wheel 3 and the magnetic guide rail groove 10 in the disc shell are both made of homogeneous and evenly distributed permanent magnet materials, forming a permanent magnet magnetic levitation rotor structure.

[0030] Embodiment 3: Superconducting maglev rotor structure

[0031] According to the Meissner effect, in the magnetic field, when the superconductor is in the superconducting state, the magnetization generated inside it completely cancels the external magnetic field, and the internal magnetic induction is zero. Therefore, magnetic levitation can be realized by using the diamagnetism of the superconductor.

Abstract

The invention discloses a magnetic suspension rotary wing type flying disk, comprising a disk shell, a disk capsule which is arranged on the bottom of the disk shell and connected with the same, an engine which is installed in the disk capsule and a rotary wing wheel which is installed in the disk shell and is driven by the engine, wherein the rotary wing wheel is formed by the sequential connection of a rotary wing shaft, a propeller hub, propeller blades and a magnetic suspension ring to form a wheel type structure, and a magnetic guide-track groove is installed on the circumference corresponding to the magnetic suspension ring in the disk shell. The magnetic suspension ring and the magnetic guide-track groove can be made of permanent magnet materials, or superconduct materials, or normal conductive materials or ordinary conducting materials and the principle of magnetic suspension is utilized for forming the lifting of the rotary wing wheel of the flying disk. The magnetic suspension rotary wing type flying disk can prevent the rotary wing from contacting or rubbing the interior of the disk shell, increase the dynamic power conversion efficiency, reduce energy consumption, and guarantee the safe running of the rotary wing and the flying disk. The invention can be improved by the technical scheme that two sets of rotary wing wheels can be coaxially overlapped and installed in the disk shell to form a coaxial double-magnetic suspension rotary wing, thereby eliminating reactive torque formed during the rotation of the rotary wing wheel.

Description

technical field [0001] The invention belongs to the field of aviation aircraft, and in particular relates to a magnetic levitation rotor type flying saucer. technical background [0002] Most of the power of flying saucers comes from jet devices or rotating devices. Among them, the flying saucer rotating device requires a compact structure and high-speed rotating performance, which leads to friction or collision between the rotor and the saucer shell during work, and even accidents; at the same time, due to the wear and tear of the mechanical structure, it will greatly affect the dynamic performance of the flying saucer. and service life, specifically refer to the flying saucer provided by Chinese patent application publication "flying saucer with non-rotating body" CN 1919397A and "flying saucer" CN 1114279A. The use of magnetic levitation rotor flying saucer will greatly reduce the friction and collision of the rotor and make the flight more stable while meeting the power...
