Patent ID: 7226018

Claim:
An aircraft landing gear assembly for an aircraft, comprising: a nose gear and a main landing gear, the main landing gear comprising: a nonrotational base portion configured to connect to an airframe of the aircraft; a wheel connected to and rotatable with respect to the base portion about a rotational axis; a plurality of stators connected to the base portion, wherein each of said plurality of stators comprises a disk having a plane that is substantially perpendicular to said rotational axis; a plurality of rotors connected to the wheel and configured to rotate with respect to said stators, each of said plurality of rotors comprising a disk having a plane that is substantially perpendicular to said rotational axis; wherein each of said pluralities of stators and rotors is configured to generate an axial magnetic flux substantially parallel to said rotational axis; and wherein said pluralities of stators and rotors are configured so that interaction of their axial magnetic fluxes causes at least one of: converting electrical energy to rotational torque energy of the wheel, and converting rotational torque energy of the wheel to electrical energy of a magnitude suitable for use to decrease the rotational velocity of said wheel.
