    Abstract: A system for driving an environmental control system (ECS) of a vehicle with ground-based electrical power may include a turbine engine on board the vehicle, coupled to the ECS to pneumatically drive the ECS, and an electric machine, on board the aircraft, mechanically coupled to the turbine engine, to drive the turbine engine. A control system such that the electric machine provides motoring assistance to the turbine engine, and that the motoring assistance is limited to match the available current from the ground-based electrical power.

    Abstract: Apparatus for generating and supplying electrical power to AC loads on an aircraft may include a prime mover, an exciter generator rotatably coupled to the prime mover and a main generator with a main generator rotor electrically coupled to the exciter generator to receive AC power from the exciter generator. One or more capacitors may be electrically coupled to the main generator rotor to increase a power factor of the main generator rotor.

    Abstract: A retention component for retaining a coil in a slot of a stator for a generator having a rotor includes a first segment and a second segment, both of which are configured to be inserted into the slot. At least one of the first and second segments is made entirely of laminated sheets that together form a unitary structure of magnetic material. At least one of the first and second segments has an interfacing surface configured to directly interface a rotor surface in the absence of a structure therebetween. A channel is between the first and second segments, and a third segment that extends along and within the channel. The third segment is less magnetic or non-magnetic than at least one of the first and second elements.

    Abstract: The present disclosure broadly relates to apparatuses and methods for generating electric power. More particularly, the present disclosure relates to a self-excited electric generator. The self-excited electric generator may include auxiliary windings to provide a source of electricity to an associated generator control unit (GCU). The apparatuses and methods of the present invention may provide added benefits of reducing excitation requirements from the GCU. Thereby, the apparatuses and methods may reduce cost, weight, and size of an electric generator, and may increase reliability of associated systems.
