ABSTRACT:
A work reducing composite engine system that uses ambient air for a primary energy source. The device consists of a unitary turbine/compressor assembly utilizing a turbine for producing work output and a downstream compressor for receiving fluid exhaust of the turbine and for compressing the turbine exhaust. An internal heat exchanger is provided between the turbine and the compressor so that fluid in the compressor is cooled, thereby reducing compression work requirements and the turbine exhaust is heated by the compressor, thereby decreasing input heat requirements.
