Abstract Society is going through transformations at a rate that is unprecedented in human history. One such transformation is the energy transition, which will affect almost every facet of our society. Gas turbine engines are state of the art machines, a backbone of modern society, and used in various applications, right from power generation to propelling aircraft and ships. This paper reviews the possibilities offered by the Inter-stage Turbine Burner (ITB) configuration for both aviation and power generation with a view on sustainability and fuel flexibility. First, the thermodynamic characteristics of a Brayton-Joule cycle with ITB is elaborated, followed by discussions on the design and the off-design performance characteristics of such a gas turbine architectural variation. Finally, the viability of ITB architecture in reducing emissions and enabling “Energy Mix” in aviation is elaborated. The paper concludes with an outlook on the technological readiness ladder that the engineering community will have to address in the future.
Highlights Using an ITB relaxes the design constraints imposed by off-design requirements, improving the engine mission performance. Using an ITB reduces the turbine inlet temperature substantially and the associate cooling requirements and NOx emissions. The working environment of ITB allows the application of the low NOx flameless combustion technique in aircraft engines. Using an ITB enables the “energy mix” concept, allowing cryogenic fuels, like LH2, to be used for future aviation.
