Classification: CPC F  H | IPC F  H

Claim 10:
11. A vehicle, comprising:
a propulsion system; and
an electrical power generation system operably connected to the propulsion system, comprising:
one or more fuel storage tanks configured to store a fuel;
one or more compressed air tanks connected to utilize compressed air to provide a motive pressure to drive liquid fuel from the one or more fuel storage tanks through a turbine speed control valve within a micro-turbine alternator;
the micro-turbine alternator, comprising:
a combustion chamber;
at least one turbine driven by combustion gases from the combustion chamber;
a first stage compressor;
a second stage compressor located aft of the first stage compressor, the first stage compressor and the second stage compressor being operably connected to the combustion chamber to provide a compressed airflow thereto;
one or more shafts connecting the at least one turbine to the first stage compressor and the second stage compressor such that rotation of the at least one turbine drives rotation of the first stage compressor and the second stage compressor, the one or more shafts including a compressor shaft attached or operably connected to the first stage compressor, a turbine shaft attached or operably connected to the at least one turbine, and a coupling assembly operably connecting the turbine shaft to the compressor shaft, and wherein an inlet hub of the micro-turbine alternator has a diameter at a forward edge of the first stage compressor less than a diameter of the compressor shaft; and
an electric generator disposed along the one or more shafts such that electrical power is generated via rotation of the one or more shafts, wherein the electric generator is disposed along the one or more shafts between the first stage compressor and the second stage compressor.
