Systems and methods are provided for distributing DC power in an aircraft. In one example, a method is provided that includes generating a plurality of DC voltages from a plurality of independent sources driven by one or more turbines of the aircraft, providing each of the plurality of DC voltages to respective dedicated DC buses, and setting a plurality of switches that selectively couples a first set of dedicated DC buses to a synchronization bus to allow for bus sharing between the first set of dedicated DC buses and bus isolation of a second set of dedicated DC buses.

Aircraft DC power distribution systems and methods

An apparatus is provided for supplying electrical power and cooling for an aircraft. The apparatus includes a cooling turbine coupled to a shaft, a compressor coupled to the shaft, and including an input for receiving engine bleed air or ambient air, and an output for discharging compressed air, a flywheel coupled to the shaft, a power turbine coupled to the shaft, and a starter generator coupled to the shaft between the compressor and the power turbine.
