Zusammenfassung:	The invention relates to secondary power system (10) apparatus and method for use aboard aircraft in place of conventional auxiliary power units (APU's) and emergency power units (EPU's). The invention integrated power unit (12) (IPU) performs the function of both an APU and an EPU, while avoiding the use of hazardous monofuels. The IPU (12) includes a turbine engine (20) operable on pressurized ambient air, or on pressurized stored air, along with jet engine fuel. The structure of a combustion chamber (26) for the engine which is able to use pressurized air from two separate sources; of a control (18) able to selectively operate the engine as an EPU, as an APU, and to effect operating transition from EPU to APU; and of a complete secondary power system (10) with the IPU (12) are all disclosed.
