Effective date : A magnetic suspension electric rotor flying saucer comprises: a saucer shell 1 , a saucer cabin 2 , a rotor system 3 , and a control system 4. The rotor wing system is a magnetic suspension electric rotor wing system 3 composed of a magnetic suspension rotor wing wheel 5 , an electrodynamic ring 6 , a magnetic suspension shaft 7 and magnetic suspension lead rails 8. The electrodynamic ring 6 , the magnetic suspension shaft 7 and the magnetic suspension lead rails 8 are fixed on the saucer shell 1.
The magnetic suspension rotor wing wheel 5 is suspended in space limited by the electrodynamic ring 6 , the magnetic suspension shaft 7 and the magnetic suspension lead rails 8 and rotates around the magnetic suspension shaft 7 by the electromagnetic thrust. The lift and thrust of a rotary-wing aircraft are formed by a rotary wing rotating at a high speed. The power for the rotation of the rotary wing comes from an engine.
The current rotary-wing aircrafts include all kinds of rotary-wing helicopters. The rotary wing and engine are two separate and independent systems and connected with a transmission mechanism.
Compared with ordinary rotary-wing aircrafts, the particularity of a rotary-wing flying saucer is that the rotary-wing system and its power system need to be installed inside a saucer shell.
The internal space of the saucer shell is limited and restricts the structure and layout of the rotary-wing system and its power system.
Therefore, the paramount task for the design of a rotary-wing flying saucer is how to make full use of the limited internal space of the saucer shell and design a rotary-wing system and its power system with a compact structure, reasonable layout, small weight, high motive power conversion efficiency and easy manipulation and control.
When the rotary wing rotates at a high speed in the saucer shell, due to pneumatic vortex, flexibility of the rotary wing, maneuver of the saucer and other factors, the rotary wing and the saucer shell might collide with each other, resulting in failure and even a serious accident.
For more information, please refer to Patent CN A. There exists the foregoing defect. Therefore, one of the important tasks for the design of a rotary-wing flying saucer is how to avoid the contact and friction between the high-speed rotary wing and the interior of the saucer shell, reduce the noise of the rotary wing during high-speed rotation as well as the vibration of the saucer shell and the saucer cabin, raise motive power conversion efficiency, reduce energy consumption and guarantee the operational safety of the rotary wing and the flying saucer.
Similar to ordinary rotary-wing aircrafts, reactive torque will be generated when the rotary wing of a flying saucer rotates.
There is the problem that the body of the flying saucer suffers uncontrollable reactive torque. Therefore, how to overcome the reactive torque of the rotary-wing flying saucer is also another important task for the design of a rotary-wing flying saucer. The object of the present invention is to make full use of the limited internal space of the saucer shell and design and construct a rotary-wing flying saucer which has a compact structure, reasonable layout, small weight, high motive power conversion efficiency and owns an easily manipulated and controlled rotary-wing system and its power system.
The electrical driven flying saucer based on magnetic suspension provided in the present invention comprises a saucer shell, a saucer cabin, a rotary-wing system and a control system, wherein the rotary-wing system is a magnetic suspension electromotive rotary-wing system and comprises magnetic suspension rotary-wing wheels, an electromotive ring, a magnetic suspension shaft and a magnetic suspension guide rail.
The electromotive ring, the magnetic suspension shaft and the magnetic suspension guide rail are fixed to the saucer shell. The magnetic suspension rotary-wing wheels are suspended in the space restricted by the electromotive ring, the magnetic suspension shaft and the magnetic suspension guide rail and go around the magnetic suspension shaft under an electromagnetic thrust.
The magnetic suspension rotary-wing wheels comprise blades, a magnetic suspension inner ring and a magnetic suspension outer ring. The blades are connected between the magnetic suspension inner ring and the magnetic suspension outer ring along the radial direction X-X to form an impeller.
The magnetic suspension guide rail includes a magnetic suspension inner ring guide rail and a magnetic suspension outer ring guide rail. The magnetic suspension inner ring guide rail comprises an inner ring upper guideway and an inner ring lower guideway.
The magnetic suspension outer ring guide rail comprises an outer ring upper guideway and an outer ring lower guideway. The magnetic suspension inner ring of the magnetic suspension rotary-wing wheels surrounds the magnetic suspension shaft in the radial direction X-X and is disposed between the inner ring upper guideway and the inner ring lower guideway in the axial direction Y-Y.

This paper deals with the design of a shock absorbing system with a rack and pinion mechanism of a suitable gear ratio which harvests electric energy from the shocks and impulses generated during the driving.
The integration of this system with hybrid or electric vehicles will result in the vehicle having a better range. They provide with consistent contact, comfort and control and hence maximizing friction between tires and surface of the road during any type of motion [1]. Suspension systems also provide steering stability and improves the handling of the vehicle.
A basic suspension system takes into use of the tires, tire air, springs, shock absorbers and auxiliaries which act in unison to absorb the energy of vertically accelerated wheel allowing the frame and body of a vehicle to be undisturbed whilst holding the road, thus isolating the vibrations.
Suspension Systems are sub-categorized into the following: x Conventional Dependent Suspension System x Independent Suspension System x Air Suspension System x Hydro Elastic Suspension System Independent Suspension Systems are widely used due to one major advantage, that is, the vertical motion of one wheel is independent of the other wheel.
Both, front and rear wheels are utilized actively for providing suspension, and this imparts more stability, better control and handling to the driver. A simplified Independent Suspension System is shown in Fig. This suspension system also provides us with electric power regenerated from motion of individual wheels [2].
Further design is done taking into consideration that Independent Suspension System is used. A shock absorber is a mechanical or hydraulic device which is designed in a manner which smoothens out or damps out any sudden shock or impulse by converting the Kinetic Energy in the form of Heat Energy and then dissipating it.
This energy is usually wasted in the form of heat [3]. Independent Suspension System Springs have an innate property of oscillating harmonically, which is, they oscillate for a long time period with smaller reductions in amplitude. Ideally there are no reductions in the amplitude Fig. Shock absorbers reduce the amplitude and time taken for the oscillation, and eventually damps the vibrations completely.
The amplitude of oscillation decreases with time, eventually becoming zero, and the profile of the wave is an exponentially decreasing sinusoidal wave Fig. A better understanding can be obtained from the figures below. They work on the principle that viscous fluids resist motion of the piston, due to viscous friction.
The piston has slots for the viscous fluid to pass through and are known as piston valves. Fluid in the shock absorber casing is forced to flow through restricted valves, thus generating hydraulic resistance.
This resistance is needed and provides for the damping effect [5]. Damped Oscillations Electro Magnetic Ride Suspensions are basically used to actively control the damping force of suspension system.
