1. Multi function integrated power unit apparatus comprising;

  • a first combustion turbine engine having a rotary dynamic compressor inducting and pressurizing ambient air, a first combustor receiving said pressurizing air along with a first supply of jet engine fuel to support combustion producing a first flow of motive gas, a first turbine expanding said first flow of motive gas substantially completely to ambient to rotatably drive only said compressor and a first rotatable power output shaft, a second combustion turbine engine including an inlet for receiving pressurized air from a storage source thereof, a second combustor receiving said pressurized air from said storage source via said inlet along with a second supply of jet engine fuel from a respective fuel storage source dedicated only to said integrated power unit to support combustion producing a second flow of motive gas, a second turbine expanding said second flow of motive gas substantially completely to ambient to rotatably drive only a second power output shaft, a plurality of accessory devices for consuming all shaft power from said power output shafts, gear train means drivingly connecting said plurality of accessory devices for delivery of shaft power thereto only from said first power output shaft and said second power output shaft, and one-way overrunning clutch means for drivingly connecting the one of said first power output shaft and said second power output shaft having the higher rotational speed to drive said gear train means while overrunning with respect to the other of said first power output shaft and said second power output shaft.
