Abstract
An aircraft powerplant assembly includes a gearbox and a power coupler. The gearbox includes a first power transfer apparatus and a second power transfer apparatus independent of the first power transfer apparatus. The power coupler includes a clutch. The first power transfer apparatus is configured to operatively couple and transfer mechanical power through the gearbox between a first engine apparatus and an engine accessory. The power coupler is configured to operatively couple a power coupled accessory to the second power transfer apparatus when the clutch is engaged. The second power transfer apparatus and the power coupler are collectively configured to operatively couple and transfer mechanical power through the gearbox between a second engine apparatus and the power coupled accessory when the clutch is engaged. The power coupler is configured to operatively decouple the second power transfer apparatus from the power coupled accessory when the clutch is disengaged.
