Abstract
A recuperated gas turbine engine. The gas turbine engine includes a heat exchanger, and gas turbine (including compressor, can-type combustor and turbine). The heat exchanger includes a compressed air passageway and a turbine exhaust gas passageway adjacent to each other within the casing which extend spirally throughout the heat exchanger and towards an inner cylindrical chamber in which the combustor is positioned approximately to the center of the casing. Improved engine fuel efficiency is achieved by preheating the compressed air before it reaches the combustor with the higher-temperature exhaust gas. A can-type combustor is used for alleviating heat-dissipation issues to improve efficiency of the combustion. A concentric back-to-back rotor arrangement significantly shortens the length of a conventional engine turbine rotor which improves on the operational stability of a gas turbine engine.
