SUPPLEMENTAL ENGINE POWER CONTROL

A rotorcraft (10) has a drive system including a main rotor (12) coupled to a main rotor gearbox (34) to rotate the main rotor (12) at a rotor speed, a main engine (32) coupled to the drive system to provide a first power, a supplemental engine (40) coupled, when a first clutch is engaged, to the dr...

Beschreibung
Zusammenfassung:	A rotorcraft (10) has a drive system including a main rotor (12) coupled to a main rotor gearbox (34) to rotate the main rotor (12) at a rotor speed, a main engine (32) coupled to the drive system to provide a first power, a supplemental engine (40) coupled, when a first clutch is engaged, to the drive system to provide a second power additive to the first power, and a control system operable to control the main engine (32) and the supplemental engine (40) to provide a total power demand, where the main engine (32) is controlled based on variations in rotor speed and a power compensation command to produce the first power, and the supplemental engine (40) is controlled to produce the second power in response to a supplemental power demand.
