    Abstract: A method of operating a multi-engine drive system of an aircraft includes driving a main rotor of the aircraft by a main engine of the multi-engine drive system at an operating speed of the main engine, operating a supplemental engine of the multi-engine drive system at approximately 80% of an operating speed of the supplemental engine, wherein, during the operating step, a clutch interoperably coupled to the supplemental engine is interoperably decoupled from the main rotor and, responsive to a command to interoperably engage the clutch, if the clutch successfully engages such that the clutch is interoperably coupled to the main rotor, providing, by the supplemental engine, power to the main rotor.

    Abstract: In an embodiment, an aircraft includes a drive system, a main engine coupled to the drive system to provide first power, and a supplemental engine coupled to the drive system to provide second power additive to the first power. The aircraft also includes a control system to control the main engine and the supplemental engine to optimize usage of the supplemental engine. The control system is operable to maintain the supplemental engine in a reduced power state at least until a determination is made that supplemental power is needed to satisfy a total power demand of the drive system. The control system is also operable to determine that supplemental power is needed to satisfy the total power demand of the drive system. The control system is further operable to increase a power level of the supplemental engine in response to the determination that supplemental power is needed.
