초록

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 ...
