[0042] Manned flying saucers are one of the most promising modes of urban air transportation in the future, but there is currently a lack of research on saucer-shaped aircraft.

[0043] The magnetic levitation power system and magnetic levitation manned flying saucer provided in this application are intended to solve the above technical problems of the prior art.

Specifically, the control unit 21 and the sensors 22 transmit signals via wired or wireless means.

[0047] The magnetic levitation system 1 includes a magnetic levitation motor and a blade 10 fixed on the power output end of the magnetic levitation motor. The magnetic levitation motor is configured to work according to the operation information under the control of the control unit to drive the blade 10 to rotate, so that the magnetic levitation manned flying saucer operates according to the operation information. Specifically, the multiple sensors 22 also include a gyroscope, an acceleration sensor 22, and a magnetic sensor 22. Specifically, the magnetic levitation motor includes a rotor 11, a stator 12, a housing 13, a thrust magnetic levitation bearing 14 and a radial magnetic levitation bearing 15, a sensor 16 and a magnetic levitation controller 18.

When an electrical signal is provided to the stator 12, the stator 12 generates a magnetic field so that the rotor 11 rotates.

[0055] Specifically, the electromagnetic flux of the thrust magnetic bearing 14 and the electromagnetic flux of the radial magnetic bearing 15 generate the electromagnetic force of the stator 11 in the axial direction and the rotor in the radial direction, which can control a controllable gap between the rotating rotor 11 and the stator 12. The controllable gap makes the rotor 11 have no contact with the stator 12 during the rotation process.

[0056] The magnetic levitation power system provided in this embodiment, through the cooperation of the avionics system and the magnetic levitation system 1, enables the magnetic levitation motor to drive the rotation of the blades 10 to generate power, so as to serve as the power system of the magnetic levitation manned flying saucer. The advantages of the magnetic levitation motor mainly include no friction, no wear, high precision, high efficiency, etc.; the magnetic levitation motor realizes rotation without mechanical contact, so there is no mechanical wear and friction resistance, thereby improving the reliability and life of the magnetic levitation motor; in addition, the magnetic levitation motor has high precision and fast response speed, so the control accuracy is high; finally, the magnetic levitation motor has high efficiency, can reduce energy consumption and reduce operating costs.

[0059] Specifically, in an optional embodiment, the communication unit uses a communication mode based on a 5G / 5G-A ground communication base station. With the development of satellite Internet, ground base stations and satellite Internet can work together to fully meet the communication needs of the maglev manned flying saucer. In addition, in order to meet the airworthiness requirements, the maglev manned flying saucer adapted by the maglev power system provided in this embodiment is equipped with at least two VHF radio stations.

[0060] like Figure 4 As shown, in the magnetic levitation power system provided in this embodiment, the avionics system 2 also includes a navigation system, and the navigation system includes one or more of an inertial navigation system, a satellite navigation, a micro-electromechanical sensor 22, a magnetic compass, an airspeed meter, a barometric altimeter / radar altimeter, etc.

It should be noted that the "three directions" mentioned in this application are the directions of the xyz axes in the spatial rectangular coordinate system.

[0064] Specifically, in the magnetic levitation power system provided in this embodiment, the multiple sensors 22 also include a gyroscope, an acceleration sensor, and a magnetic sensor. In combination with the above sensors, the calculation process of the control unit 21 is as follows:

[0065] The control unit 21 calibrates the three-axis angular velocity values ​​according to the sampling values ​​of the gyroscope to obtain the angular velocity ω1 / ω2 / ω3, corrects the drift of the angular velocity ω1 / ω2 / ω3, and then performs a second-order Picard algorithm on the angular velocity ω1 / ω2 / ω3 after the drift correction to obtain the real-time quaternion q1 / q2 / q3 / q4, inputs the real-time quaternion q1 / q2 / q3 / q4 into the Euler angle conversion technical formula, and calculates the Euler angle ψ1 / ψ2 / ψ3.

[0066] The control unit 21 calibrates the three-axis acceleration value according to the sampling value of the acceleration sensor to obtain the acceleration a x / a y / a z , for the three-axis acceleration a x / a y / a z The control unit 21 calibrates the three-axis magnetic value m according to the sampling value of the magnetic sensor x / m y / m z .

[0067] Among them, the angular velocity correction value e used to correct the drift of angular velocity ω1 / ω2 / ω3 is x / e y / e z It is determined based on the calculation error, which is determined by the three-axis magnetic value m x / m y / m z Perform attitude calculation and convert the three-axis magnetic force value m x / m y / m z The attitude solution result and the three-axis acceleration a x / a y / a zThe result after smoothing filtering and the quaternion value of the previous moment are fused and solved.

[0068] Therefore, the control unit 21 controls the magnetic levitation motor based on the above-mentioned sensors and solution methods, so that the magnetic levitation power system provides the required power.

[0069] Based on the same inventive concept, the present application also provides a magnetically suspended manned flying saucer, such as Figures 5 to 8 As shown, the magnetic levitation manned flying saucer provided in this embodiment includes the magnetic levitation power system of any one of the above embodiments, and has the beneficial effects of the magnetic levitation system in the above embodiments, which will not be repeated here.

The housing 13 of the magnetic levitation motor is fixed to the inner wall of the duct 32 through a connector 19.
