ABSTRACT:
An additional turbine, an air-to-water heat exchanger, and an air-to-air heat exchanger are added upstream of a recuperated gas turbine engine. Incoming air at atmospheric temperature is expanded and cooled in the additional turbine and then passes through the air-to-water heat exchanger where it is used to cool warm water to a suitable drinking temperature. The cool air then passes through the air-to-air heat exchanger, where it precools the incoming atmospheric temperature air. The output shaft of the additional turbine is coupled to an additional compressor downstream of the original compressor of the engine, thus resulting in a higher net pressure ratio.
