Abstract: A generator and/or motor device that includes an inner stator having one or more inner coils, an outer stator shell having one or more outer coils, and a rotor assembly arranged radially between, and configured to rotate relative to, the inner stator and the outer stator shell. The rotor assembly has one or more outer magnetic elements adjacent to the outer coils and has one or more inner magnetic elements adjacent to the inner coils. An electromotive force may be generated in at least one of the inner and outer coils upon relative rotation of the rotor assembly. Alternatively, relative rotation of the rotor assembly may be caused upon an electromotive force being applied in at least one of the inner and outer coils. The rotor assembly may be attached to an input shaft. The rotor assembly includes a rotor spool to which the inner and outer magnetic elements are secured.

Abstract: A cooling air transferring apparatus is provided particularly for transferring cooling air from hollow convergent flaps and seals to hollow divergent flaps and seals respectively in aircraft gas turbine engine variable nozzles. The preferred embodiment includes two semi-circular tubes, the first partially received within the second and both having a common center and radius of curvature so as to slide about the pivot point of the variable nozzle's pivotable convergent and divergent flaps and seals. The preferred embodiment further includes an entrainment opening on the second tube through which part of the first tube is received. The entrainment opening induces cooling air from the nozzle bay into the cooling air transfer tube to help cool the divergent flaps and seals.
