Method and apparatus for combined levitation and guidance along guideway curvature in electrodynamic magnetically levitated high speed vehicle

An electrodynamic magnetic levitation and guidance system, said system including the combination of:

• a guideway;
• a vehicle which travels along the guideway;
• an array of secondary conductors arranged along said guideway, said conductors each having a spatially dependent inductance to resistance electrical time constant and a spatially variable coil internal impedance;
• an array of uniformly constructed primary field electromagnetic coils on said vehicle which produce a vertically orientated magnetic field to interact with said secondary conductors and developing a levitation force capable of suspending said vehicle in regard to the secondary conductors, said vehicle experiencing two or greater bidirectional electrodynamic forces from the array of secondary conductors and array of primary field coils for creating a differential in levitation force across the width of the vehicle to offset centrifugal forces acting on the vehicle;
• a controllable electrical power supply for regulating said primary field coils, said power supply connected to the primary field coils;
• null-flux electrical loop control means located on the guideway operative to regulate the magnetic field linking the secondary conductors to the primary field coils, such that the magnetic field produces a differential levitation force across the width of the guideway for offsetting the centrifugal force acting on said vehicle, said control means in communication with said array of field coils.
