Unmanned underwater vehicle propulsion system including an AC power distribution bus

摘要

A propulsion system for an unmanned underwater vehicle includes a turbine engine having a rotational output, an electrical generator mechanically connected to the rotational output and electrically connected to an Alternating Current (AC) power bus. A magnitude of an AC output of the electrical generator is independent of rotational speed of the rotational input. An electrical motor connected to the AC power bus, and includes a mechanical output.
