초록

An accessory driving apparatus for an aircraft system is connected to an accessory unit to be driven, such as a PCU pump. A gear set for transferring rotational power from the driving shaft to the driven shaft is provided for selective arrangement in first and second configurations in order to permit the driving shaft to rotate in either rotational direction without affecting a predetermined rotational direction of the driven shaft.

청구항

I claim: 1. A method for powering respective first and second propeller control unit (PCU) pumps of respective first and second propeller engines of a multi-engine aircraft, the first and second engines having respective pump driving shafts which rotate in opposite rotational directions relative to one another when the aircraft is operated, the method comprising the steps of: providing a driven shaft of the first PCU pump disposed at an angle with respect to the pump driving shaft of the first engine; providing a driven shaft of the second PCU pump disp...
