Abstract
A gas turbine engine including a compressor, a pressure-gain combustor, and a turbine is disclosed. The compressor compresses air drawn into the engine and delivers high pressure air to the pressure-gain combustor. In the pressure-gain combustor, fuel is mixed with the high pressure air and is ignited. Products of the combustion reaction in the pressure-gain combustor are directed into the turbine at a pressure greater than that of the air discharged by the compressor. In the turbine, work is extracted by actively cooled turbine blades to drive the compressor and, sometimes, an output shaft. In illustrated designs, some compressed air from the compressor is diverted around combustion in the combustor to provide active cooling for the turbine blades.
