System and method for controlling engines of a multi-engine aircraft engine assembly

A method for controlling engines of a multi-engine aircraft engine assembly, the method comprising:

• identifying a first operating rule for a first engine of the multi-engine aircraft engine assembly, and the first operating rule includes a first target rate of change of a first engine power for the first engine;
• identifying a second operating rule for a second engine of the multi-engine aircraft engine assembly, the second operating rule includes a second target rate of change of a second engine power for the second engine, and the first target rate of change of is different than the second target rate of change;
• and
• controlling the first engine power of the first engine using the first operating rule and controlling a the second engine power of the second engine using the second operating rule to power an engine load with each of the first engine and the second engine;
• wherein the first engine has a first power output capacity, the second engine has a second power output capacity, and the first power output capacity is different than the second power output capacity.

An engine assembly for a multi-engine aircraft, the engine assembly comprising:

• a propulsor;
• a plurality of engines including at least a first engine and a second engine, and each of the first engine and the second engine are coupled to the propulsor by a gear assembly;
• and
• at least one controller including a processor in communication with a non-transitory memory storing instructions, which instructions when executed by the processor, cause the processor to:
• identify a first operating rule for the first engine and a second operating rule for the second engine based at least on a quantity of accumulated engine loading cycles of each of the first engine and the second engine, the first operating rule including a first target rate of change of a first engine power parameter, and the second operating rule including a second target rate of change of a second engine power parameter which is different than the first target rate of change of the first engine power parameter;
• and
• control the first engine power parameter of the first engine using the first operating rule and control the second engine power parameter of the second engine using the second operating rule.
