ABSTRACT:
The present invention provides a multi-mode secondary power unit comprising a first starter/generator unit operably coupled to a shaft. The first starter/generator motor is operable in a motor mode for causing rotational movement of the shaft and is operable in a generator mode for generating electric power from rotational movement of the shaft. A thermal engine is operably coupled to the shaft and is operable in a fuel burning mode for causing rotational movement of said shaft and is operable in a non fuel burning mode for receiving rotational movement from the shaft. A load compressor is operably coupled to the shaft for pressurizing air to a predetermined level.
