Abstract
A propulsion system for an unmanned underwater vehicle includes a turbine engine, a generator mechanically coupled to an output shaft of the turbine engine, an electrical motor mechanically decoupled from the turbine engine and electrically coupled to the generator via a power bus architecture, and a propulsor mechanically coupled to a rotational output of the electrical motor. The power bus architecture includes a pair of AC buses and a DC bus.
Claims5
A method for driving an unmanned underwater vehicle propulsion system comprising:
- providing power from an electrical energy storage system to a generator via a DC bus and a pair of AC buses in an engine start mode;
- providing power from the electrical energy storage system to a motor via the DC bus and the pair of AC buses in a range mode;
- and
- providing power from the generator to the motor via the pair of AC buses in a sprint mode.
