Abstract
A method of controlling a flow of a fuel mixture of different types of fuel in a gas turbine engine is described which includes determining a combustive energy value of an input of the fuel mixture in the engine, extracting fuel schedule data from a fuel schedule established for a reference fuel, determining a desired fuel mixture flow rate by adapting the fuel schedule data to the fuel mixture based on the combustive energy value, and controlling a fuel metering device of the engine such that the fuel mixture flow rate corresponds to the desired fuel mixture flow rate.
