Innovative Gas Turbine Architecture

University of Notre Dame Background
Gas turbines are widely used for propulsion mobility applications, including flight, ground, and marine vehicles, as well as for land-based power generation. Conventional gas turbines engines ingest air from the atmosphere which is compressed, heated through fuel-added combustion, and expanded to produce power. Key considerations when selecting an engine include system efficiency/fuel burn rate, weight, cost, reliability, and emissions. Due to the broad usage of gas turbine engines, the market is continually investing in new technologies to deliver improvements of these critical attributes.
Technology Overview
Researchers at the University of Notre Dame have recently developed an innovative gas turbine cycle architecture particularly applicable for propulsion mobility applications. This engine architecture integrates a closed-loop power and thermal management cycle in an innovative manner that radically changes the engine configuration and system efficiency. A significant benefit of this architecture is the elimination of the complex shafting characteristic of conventional gas turbine engines allowing novel packaging. The architecture also provides higher cycle thermodynamic efficiency and improved power to weight. This innovation is a disruptive change that provides significant benefit and supports the ongoing evolution of the mobility and power generation industries.
