Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
97 words
IN OPERATIVE ASSOCIATION WITH A GAS TURBINE ENGINE, HAVING A COMPRESSOR SUPPLYING COMPRESSED AIR THROUGH A HEAT RECUPERATOR TO FUEL COMBUSTION CHAMBER, A FUEL CONTROL COMPRISING: MEANS SUPPLYING FUEL TO SAID COMBUSTION CHAMBER, AT A RATE VARYING IN ACORDANCE WITH THE MASS RATE OF AIR FLOW THERETO, AND MEANS FOR AUTOMATICALLY MODIFYING THE RATE OF SAID FUEL SUPPLY, IN ACCORDANCE WITH A FUNCTION OF THE PRODUCT OF THE COMPRESSOR DISCHARGE PRESSURE AND THE TEMPERATURE OF THE AIR LEAVING SAID RECUPERATOR, SO THAT THE TEMPERATURE OF THE GASES LEAVING SAID COMBUSTION CHAMBER NEVER EXCEEDS A PRESELECTED MAXIMUM LIMIT.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
95 words
IN OPERATIVE ASSOCIATION WITH A GAS TURBINE ENGINE, COMPRISING: A FIRST, LOW-PRESSURE AIR COMPRESSOR, DRIVEN BY A FIRST GAS TURBINE; A SECOND, HIGH-PRESSURE AIR COMPRESSOR, DRIVEN BY A SECOND GAS TURBINE; FOR SUPPLYING COMPRESSED AIR THROUGH A HEAT RECUPERATOR TO A FIRST FUEL COMBUSTION CHAMBER; AND A SECOND FUEL COMBUSTION CHAMBER, INTERPOSED IN GAS FLOW SERIES RELATION BETWEEN SAID FIRST AND SECOND TURBINES; A SINGLE-UNIT FUEL CONTROL, COMPRISING: A MANUAL POWER CONTROL LEVER, MEANS FOR COORDINATELY REGULATING FUEL FLOW FROM A COMMON SUPPLY SOURCE TO SAID FIRST AND SECOND COMBUSTION CHAMBERS, SO AS TO MAINTAIN
