Designing a Probable Engine for Future Supersonic Transport Aircraft

Supersonic transport (SST) is poised to revolutionize the aviation industry once again, offering the potential for significantly reduced travel times across transcontinental and transoceanic routes. This paper delves into the key engine design elements for next-generation SST aircraft, focusing on critical areas such as fuel efficiency, environmental sustainability, and noise reduction. With a particular emphasis on low-bypass turbofan engines, variable cycle technology, and afterburner integration, this paper provides a comprehensive analysis of the technological advancements necessary to address the challenges that previously plagued supersonic transport, such as the high fuel consumption and environmental impact of earlier designs like the Concorde [1]. The paper also explores the role of alternative fuels—namely, sustainable aviation fuel (SAF) and liquid hydrogen—and their implications for the future of high-speed aviation. Through computational modeling and materials analysis, the paper proposes a conceptual engine model that balances performance, sustainability, and regulatory compliance. Areas for future research, particularly in noise abatement and thermodynamic efficiency, are also outlined.
