The vortex turbine (30) includes a first and a second array (38, 40) of blades (32a, b) (34a, b) extending respectively from a first and a second hub section (32, 34). Hub sections (32, 34) may be independently pivoted about a common axis of rotation (36) to a stowed position for landing, take-off, or ground operation, whereat none of the blades (32a, b) (34a, b) extend below a minimum ground clearance of the aircraft, or beyond a maximum horizontal extension of the wing (16). In flight, the hub sections (32, 34) may be deployed and the pitch of the blades adjusted to maximize dissipation of the lift induced vortex (28), thereby minimizing drag and providing improved safety for other aircraft flying through the wake of the aircraft (10) producing the vortex (28). The hub sections (32, 34) may also be locked together to form a turbine wheel (46) having a circumferentially symmetrical array of blades. The turbine wheel (46) is rotatable about the axis of rotation (36) for extracting usable energy from the lift induced vortex (28) and/or free stream air passing through the turbine wheel (46).

Abstract: A switched reluctance machine comprises a stator (48) having an even plurality of salient stator poles, each of which having a stator winding disposed thereon and electrically coupled one to another to form diametrically opposed pole pairs which may be coupled to an external source of electrical energy, a rotor (20) having an even plurality of salient rotor poles (22, 24, 26, 28), and at least one compensation (30, 32, 34, 36) disposed on each of the rotor poles. The compensation coils are electrically coupled one to another to form diametrically opposed compensation pairs (30 and 32, 34 and 36) in which flows a flux generating current when one of the stator windings of a pole pair is either open or shorted. The flux generated equalizes the unbalance forces resulting from the faulted stator winding, thereby increasing the fault tolerant capability of the switched reluctance machine.
