Abstract
An emergency power unit comprises a turbine; a main combustor subsystem upstream of the turbine, with the main combustor subsystem being capable of operation at an augment power output and a main power output; a bleed air subsystem upstream of the turbine, with the bleed air subsystem capable of alternating operation with the main combustor subsystem; and a controller for controlling the operation of the said main combustor subsystem and the bleed air subsystem. In another embodiment, the emergency power unit comprises a turbine; a main combustor subsystem upstream of the turbine; a bleed air subsystem upstream of the turbine, with the bleed air subsystem capable of alternating operation with the main combustor subsystem; a secondary combustor subsystem in communication with the main combustor subsystem, while the secondary combustor subsystem is capable of simultaneous operation with either the bleed air subsystem or the main combustor subsystem; and a controller for controlling the operation of the the main combustor subsystem, bleed air subsystem, and secondary combustor subsystem.
