HIGH EFFICIENCY COMPACT GAS TURBINE ENGINE

摘要

This disclosure relates generally to the field of vehicle propulsion and power generation and, more specifically, to a gas turbine engine architecture for high efficiency shaft power output and more specifically to increasing gas turbine engine thermal efficiency to levels approaching and exceeding 50% utilizing multiple stages of intercooling and reheat, ceramic technology, turbocharger technology and high pressure combustion. The approach includes utilizing a conventional dry low NOx combustor for the main combustor and thermal reactors for the reheat apparatuses. In a first configuration, there are three separate turbo-compressor spools and a free power turbine spool. In a second configuration, there are three separate turbo-compressor spools but no free power spool. In a third configuration, all the compressors and turbines are on a single shaft. Each of these configurations include two stages of intercooling and two stages of reheat.
