MULTI-ENGINE SYSTEM AND METHOD

A method of operating a multi-engine system of a rotorcraft includes, during a cruise flight segment of the rotorcraft, controlling a first engine (10A) to provide sufficient power and/or rotor speed demands of the cruise flight segment; and controlling a second engine (10B) to by providing a fuel f...

Beschreibung
Zusammenfassung:	A method of operating a multi-engine system of a rotorcraft includes, during a cruise flight segment of the rotorcraft, controlling a first engine (10A) to provide sufficient power and/or rotor speed demands of the cruise flight segment; and controlling a second engine (10B) to by providing a fuel flow to the second engine (10B) that is between 70% and 99.5% less than a fuel flow provided to the first engine (10A). A turboshaft engine for a multi-engine system configured to drive a common load is also described.
