초록

An emergency on board power source (28) for jet aircraft having high (22) and low speed (14) spools is disclosed for operation above altitudes where auxiliary power units (14) are operational. A power takeoff (56) is provided from the low speed spool of the jet engine to drive an emergency power unit (28) for supplying electrical and/or hydraulic on board power to the aircraft to maintain control during emergency conditions during which the auxiliary power unit is not operational or is not operational to supply sufficient power to maintain hydraulic or e...
