摘要:
A landing gear for an aircraft has a set of axially spaced wheels rotatable about a common axis drive by a transverse flux drive. In another feature, a transverse flux drive includes a first rotor and a second rotor. One of the first and second rotors is positioned radially inwardly of the other. A single stator is positioned radially intermediate the first and second rotors. In another feature, a landing gear combination for use on an aircraft has a nose wheel assembly including at least one nose wheel to be associated with a nose cone on an aircraft. A main landing gear assembly is also associated with the aircraft. A transverse flux motor provides on-ground propulsion and/or braking to the aircraft.

摘要:
A dual generator system includes a main generator and an auxiliary generator. The main generator generates at least a first phase main output and a second phase main output. The auxiliary generator generates at least a first phase auxiliary output and a second phase auxiliary output, wherein the first phase auxiliary output is combined with the first phase main output to generate a first phase main output. An auxiliary generator control unit (AGCU) monitors the first phase combined output and the second phase combined output and in response independently regulates the first phase auxiliary output and the second phase auxiliary output.
