Abstract

A flying craft has an aerodynamic aircraft fuselage structure preferably disc shaped. A pair of coaxial electrokinetic motor-generators are mounted concentrically, and preferably centered within the disc shaped structure of the craft. Each of the motors is toroidal in configuration, providing a ring-shaped stator and rotor portions. The rotor portions of the motors drive counter rotating fans which are electro-magnetically levitated. The structure is open to the fans so that air may be drawn into the structure and expelled downward providing vertical lift to the aircraft. By use of auxiliary air braking flaps and electrokinetic thrusters, the craft may be tilted so as to develop a desired horizontal thrust. By impulse breaking one of the fans through tracking solenoids at different points around the stator, the aircraft may be made to rotate about its own vertical axis for changing direction. By a series of sudden braking of the motors the craft may be made to move by inertial reaction.

Dependent claims

A flying craft comprising:

an aircraft structure supporting therein a twin pair of coaxially mounted electrokinetic motor-generators;
each of the motors providing:
a motor rotor providing a fan having radial fan blades, each of the fan blades terminating at opposing ends thereof with rotor levitation solenoids;
the motor rotor further providing a plurality of tractor coils each fully embedded within one of a plurality of radial slots in a ferromagnetic material of the motor rotor, the slots and the tractor coils arranged in a circle in spaced apart positions on the motor rotor;
a motor stator secured by a plurality of radially oriented struts, the struts engaging:
a plurality of stator permanent magnet levitation solenoids, by position and orientation, electromagnetically interactive with the rotor permanent magnet levitation solenoids during rotation of the motor rotor;
a plurality of tractor solenoids, by position and orientation, electromagnetically interactive with the tractor coils during rotation of the motor rotor;
a plurality of intermediate end effect magnetic field control electromagnets at each side of the tractor solenoids, for controlling a magnetic end effect of the tractor solenoids;
and
an electrical power supply circuit providing a pulsed electrical current to the stator levitation solenoids and the tractor solenoids, the power supply circuit including a controller for synchronizing rotation between the pair of coaxially mounted motors.
