Method and arrangement for providing and controlling a gas turbine (1) at least one turbine (11, 20, 20'), at least one compressor (2, 5) driven by the turbine and a combustion chamber (16) arranged between the compressor and the turbine in the airflow path. The gas turbine includes devices (8) for direct measurement of the air mass flow at a position upstream of the combustion chamber in the airflow path, with the aim of regulating the quantity of fuel that is delivered to the combustion chamber (16) on the basis of the measured air mass flow.

What is claimed is: 1. A gas turbine (1), comprising: at least one turbine (11,20, 20'), at least one compressor (2,5) driven by the turbine and a combustion chamber (16) arranged between the compressor and the turbine in an airflow path of the gas turbine (1); and said gas turbine further comprisi
What is claimed is: 1. A gas turbine (1), comprising: at least one turbine (11,20, 20'), at least one compressor (2,5) driven by the turbine and a combustion chamber (16) arranged between the compressor and the turbine in an airflow path of the gas turbine (1); and said gas turbine further comprising measurement means (8) for directly measuring the air mass flow at a position upstream of the combustion chamber (16) in the airflow path and a regulating means that regulates the quantity of fuel delivered to the combustion chamber in dependence on the measured air mass flow; wherein the measurement means (8) further comprises one of (1) hot-film and (2) hot-wire for measurement taking. 2. The gas turbine as recited in claim 1, wherein the gas turbine (1) further comprises adjustment means (40, 40', 45) for variably adjusting geometry of at least one of the turbine (11,20, 20') and the compressor (2,5). 3. A gas turbine (1), comprising: at least one turbine (11,20, 20'), at least one compressor (2,5) driven by the turbine and a combustion chamber (16) arranged between the compressor and the turbine in an airflow path of the gas turbine (1); and said gas turbine further comprising measurement means (8) for directly measuring the air mass flow at a position upstream of the combustion chamber (16) in the airflow path and a regulating means that regulates the quantity of fuel delivered to the combustion chamber in dependence on the measured air mass flow; wherein the gas turbine (1) further comprises a heat exchanger (14) arranged between the compressor (2,5) and the combustion chamber (16) for recovering exhaust gas heat. 4. The gas turbine as recited in claim 1, wherein the measurement means (8) is arranged in the inlet to the compressor. 5. The gas turbine as recited in claim 1, wherein the gas turbine further comprises two compressors (2,5) with an intercooler (9) arranged therebetween. 6. The gas turbine as recited in claim 5, wherein the measurement means (8) is located downstream of the intercooler (9) and upstream of the second compressor (5) in the airflow path. 7. A gas turbine (1), comprising: at least one turbine (11,20, 20'), at least one compressor (2,5) driven by the turbine and a combustion chamber (16) arranged between the compressor and the turbine in an airflow path of the gas turbine (1); and said gas turbine further comprising measurement means (8) for directly measuring the air mass flow at a position upstream of the combustion chamber (16) in the airflow path and a regulating means that regulates the quantity of fuel delivered to the combustion chamber in dependence on the measured air mass flow; wherein the gas turbine (1) further comprises temperature measuring means (28) for measuring the temperature of the air at a position upstream of the combustion chamber (16) in the airflow path and a fuel regulating means for regulating the quantity of fuel that is delivered to the combustion chamber in dependence on the measured temperature. 8. The gas turbine as recited in claim 1, wherein the gas turbine (1) is incorporated into a vehicle (100) that is thereby propelled. 9. A method for controlling a gas turbine, comprising: directly measuring an air mass flow in the airflow path of the gas turbine at a position upstream of a combustion chamber (16) thererof, and regulating the quantity of fuel that is delivered to the combustion chamber based on the measured air mass flow; wherein the airflow is measured using one of (1) a hot-film and (2) hot-wire technology. 10. A method for controlling a gas turbine, comprising: directly measuring an air mass flow in the airflow path of the gas turbine at a position upstream of a combustion chamber (16) thererof, and regulating the quantity of fuel that is delivered to the combustion chamber based on the measured air mass flow; wherein the temperature of the air is measured at a position upstream of the combustion chamber (16) of the gas turbine in the airflow path and the quantity of fuel that is delivered to the combustion chamber is regulated on the basis of the measured air temperature.
