<p>A system and method of adaptively synchronizing the performance margin of a multi-engine system, eg two turbo-shaft gas turbine propulsion engines 102-1, (102-2, fig.1) in a helicopter, includes continuously, and in real-time, determining the performance margin of a first engine and the performance margin of the second engine. A difference between the performance margins of the first and second engines is calculated, and the first and second engines are controlled to attain a predetermined difference between the performance margins of the first and second engines. The feedback controller 200 of each engine's processor receives control and performance data, eg torque, turbine inlet temperature and engine speed, from the other feedback controller. The feedback controllers 200 shift load between the engines so that there is more load on the engine with the higher performance margin. Parameters that can be used as measures of performance margin include turbine inlet temperature and turbine speed.</p> |
