Abstract
In a gas-turbine engine control system, a temperature of the air supplied to mixers and a pressure of the fuel supplied to the mixers are detected and based on the detected fuel pressure, a flow rate of the fuel supplied to the mixers is determined based on at least the detected pressure of the fuel. Then, an adiabatic flame temperature in a combustion chamber is determined based on at least the determined flow rate of the fuel and it is determined whether a selected one of combustion modes including premixed combustion and diffusive combustion is to be switched to other based on the determined adiabatic flame temperature and the detected air temperature and the selected combustion mode is controlled to switch to the other in response to a result of determination. With this, it becomes possible to achieve switchover to the stabler combustion mode and realize better low emission performance by utilizing the premixed combustion range.
