A control system for gas turbines with a gas generator which comprises a compressor, a combustion chamber, and a compressor turbine, with a power take-off device and a thrust device arranged past said gas generator and adjustable as to through-put preferably in the form of an efficiency turbine provided with an adjustale guide wheel, with a thrust nozzle variable with regard to its cross section or with an adjustable propeller, and with a fuel metering valve the metering cross section of which in influenced by values of condition of state of the gas generator. As values of condition of state for the adjustment of the fuel metering valve there are selected the temperature at the entrance into the combustion chamber or at the exit of the compressor, or the pressure in front of the compressor turbine, or a setting member of a speed governor of the gas generator which adjusting member is adapted to be influenced at will. The adjustment of the through-put of the power take-off and the thrust device is effected in conformity with the differential of the measured value of the temperature at the entrance into the combustion chamber or the exit of the compressor and the setting member of the speed governor.
In combination with a gas turbine including a gas generator comprising a compressor, a combustion chamber, a speed governor, for said gas generator with a setting member therefor, and a compressor turbine;
In combination with a gas turbine including a gas generator comprising a compressor, a combustion chamber, a speed governor, for said gas generator with a setting member therefor, and a compressor turbine;
A method of controlling a gas turbine having power take-off means with a gas generator comprising a compressor, a combustion chamber, and a compressor turbine, which turbine also includes a fuel metering valve and means for controlling the cross section of said fuel metering valve in conformity with values of condition of state of the gas generator, which includes in combination the steps of employing as values of condition of state for adjusting the fuel metering valve first the temperature at the inlet to the combustion chamber and alternately at the exit of the compressor, and finally effecting the adjustment of the through-put of the power take-off means dependent upon the difference in the measuring value of the temperature at the inlet to the combustion chamber or at the exit of the compressor and the setting member for the speed governor.
