Beschreibung
Zusammenfassung:	Disclosed is a transmission having: an input shaft (220) configured to rotationally communicate with a gas turbine engine; an output shaft (230) configured to rotationally communicate with an aircraft accessory; and a gear system (330) connected between the input shaft and the output shaft, the gear system including: a plurality of clutches (420) that are axially aligned and radially offset, the plurality of clutches configured to engage in parallel the output shaft and shift the transmission to generate a plurality gear speeds; and a plurality of pistons (600) that are configured to engage the respective plurality of clutches, the plurality of pistons being hydraulically controlled and adapted to receive fluid from a respective plurality of ports (610) in the output shaft.
