Abstract

In order to enable the full potential of linear motor speeds to be applied to surface transport by curing the instability of magnetic levitation and overcoming all the problems of aerodynamic phenomena and sonic boom, the vehicle (5) is stabilised in a ring of magnetic levitation elements (2) and propelled inside a tube (1) the interior of which is maintained under a vacuum and which is accessed through a condensation lock (3). <IMAGE>

Description

A transport system in which the vehicle travels in a vacated (vacuum) tube, orientated and propelled magnetically The invention relates to a system for the fast transport of people and goods comprising a vehicle travelling along a vacated (vacuum) tube, the vehicle being orientated by surrounding magnetic levitation elements and propelled by a linear motor and gaining access to the vacuum tube through a condensation (steam or air) lock.
Magnetic levitation makes it possible to float a vehicle on opposing magnetic fields thus eliminating the friction of contact between two moving bodies.
Linear motors make possible the propulsion of a vehicle by the use of attractive or repeling magnetic forces between elements in the track and in the vehicle.
Magnetic levitation and linear propulsion can also be combined in the one element.
magnetic levitation is achieved by a number of systems described in patents beginning with thab of temper (15v4) German patent lso 643316.
Linear motor systems are described in 45 major patents since that of Meeus J. (184G) British patent o 10196.
A combinea levitation and propulsion system was demonstrated by Fellows and Laithwaite at Dulles, Washington D C in 1972 ('Transpo 72' Magnetic River).
Because of the absence of friction, magnetic levitation and linear motors used together make very high speeds possible.
The firm Linear Motors of Loughborough in England is developing a mach 6 motor.
Current applications of these methods to transport use traditional mass movement formats of train or bus on flat track in open air.
The heavy civil engineering constructions required to balance the reactive forces of forward thrust and to overcome the natural instability of magnetic levitation make these last mentioned formats too costly.
Also aerodynamic profiles will not cure the problems of sonic boom at high speed and can only slightly lessen the fourfold increase in fuel costs each time speed is doubled.
In addition high speed in air gives tendency to take off and skin heating problems.
The invention as claimed is designed to remedy these drawbacks. It solves the problem of magnetic levitation stability by surrounding the vehicle by diametrically opposed balancing forces and solves all the problems of aerodynamic phenomena at any speed by placing the vehicle in vacuum thus lowering construction and fuel use costs.
The advantages offered by the proposed invention are mainly that the magnetic levitation elements can have a simpler outline since they are only required to prevent spin in addition to levitating, and vehicle is stable in a circie of repulsion, that propulsion thrust required for acceleration will be in simple direct proportion to the higher or lower speed attained, that momentum achieve will not be reduced by air pressure that the passage of a vehicle will be noiseless whatever its speed, that vehicle speeds will not be restricted by aerodynamic factors.
One way of carrying out the invention is described below with reference to simplified drawings which illustrate only one specific embodiment, in which: Figure 1 is a simplified cross section of the vacuum tube with square sectioned vehicle suspended between four levitation elements, one at each corner, figure 2 is a do metric projection showing a simplified outline of the system.
The figures show a transport system in which the vehicle 5 travels in a vacated tube, orientated and propelled magnetically, comprising essentially a vacuum tube 1 with four levitation elements 2, and a condensation lock 3 with two sliding access doors/ports 4.
