Abstract
There is provided a system and a method for operating a multi-engine rotorcraft. When the rotorcraft is cruising in an asymmetric operating regime (AOR) at least one engine is an active engine and is operated in an active mode to provide motive power to the rotorcraft and at least one second engine is a standby engine and is operated in a standby mode to provide substantially no motive power to the rotorcraft, at least one of a power level of the at least one second engine is increased and at least one variable geometry mechanism of the at least one second engine is moved to shed any ice accumulation on the at least one second engine.
Claims22
A method for operating a multi-engine rotorcraft, the method comprising:
- when the rotorcraft is cruising in an asymmetric operating regime (AOR) in which at least one engine is an active engine and is operated in an active mode to provide motive power to the rotorcraft and at least one second engine is a standby engine and is operated in a standby mode to provide substantially no motive power to the rotorcraft, at least one of increasing a power level of the at least one second engine and moving at least one variable geometry mechanism of the at least one second engine to shed any ice accumulation on the at least one second engine.
A system for operating a multi-engine rotorcraft, comprising:
- a processing unit;
- and
- a non-transitory computer-readable medium having stored thereon program instructions executable by the processing unit for:
- when the rotorcraft is cruising in an asymmetric operating regime (AOR) at least one engine is an active engine and is operated in an active mode to provide motive power to the rotorcraft and at least one second engine is a standby engine and is operated in a standby mode to provide substantially no motive power to the rotorcraft, at least one of increasing a power level of the at least one second engine and moving at least one variable geometry mechanism of the at least one second engine to shed any ice accumulation on the at least one second engine.
