Weight and spatial concerns in aircraft are alleviated or minimized through a combined auxiliary and emergency power unit including a gear box 10 adapted to drive a generator 16 and a hydraulic pump 18 as auxiliary to emergency power supplies for the aircraft. The system includes a pair of turbine wheels 22 and 24 along with a pair of motion transmitting paths 12, 26, 42; 14, 68, each including a selectively operable clutch 42, 68 so as to connect the turbine wheels 22, 24 to the gear box 10 in mechanical parallel. A rotary compressor 28 is connected to ...


CM,1. A combined auxiliary and emergency power unit comprising: a gear box; energy producing equipment mechanically coupled to said gear box to be driven when said gear box is provided with a rotary power input; first and second turbine wheels; first and second clutches for respectively coupling said first and second turbine wheels to said gear box to provide a rotary power input thereto; a rotary compressor connected to said first turbine wheel to be driven thereby and for providing a compressed air source; a first combustor for receiving fuel and compr...
