Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
A gas turbine engine comprising: an air compressor; a combustion chamber connected to said air compressor for burning fuel with air from said air compressor, said combustion chamber including means for receiving water and combining said water with gases generated by the burning of said fuel to generate a gaseous output; first and second turbines driven in parallel by said gaseous output of said combustion chamber, said first turbine accommodating a maximum mass flow that is greater than or equal to the maximum gaseous output of said combustion chamber in the absence of said water and less than the maximum mass output of said combustion chamber in the presence of said water; and means for recovering heat from said gaseous output after said gaseous output has passed through said turbines.
Claim 2
Dependent Claim
130 words
A gas turbine engine comprising: an air compressor; a combustion chamber connected to said air compressor for burning fuel with air from said air compressor, said combustion chamber including means for receiving water and combining said water with gases generated by the burning of said fuel to generate a gaseous output; first and second turbines driven in parallel by said gaseous output of said combustion chamber, said first turbine accommodating a maximum mass flow that is greater than or equal to the maximum gaseous output of said combustion chamber in the absence of said water and less than the maximum mass output of said combustion chamber in the presence of said water; and means for recovering heat from said gaseous output after said gaseous output has passed through said turbines.
