Comparative assessment of different propulsion cycles for turbojet applications

The quest for more efficient propulsion systems and the necessity to align with the ambitious long-term goals for emission reduction has prompted an investigation into various thermodynamic cycles. This research presents a comparative assessment of different propulsion cycles for turbojet applications, focusing on the Brayton-Joule cycle, in both simple and regenerative configurations, and on the Atkinson-Humphrey cycle. Utilizing MATLAB simulations, the performance characteristics of these cycles are analyzed and compared. MATLAB programming allows for the simulation and modeling of the thermodynamic cycles under various operating conditions and parameters: the performance of the cycles is evaluated for various compression ratios and different flight Mach numbers. Performance metrics such as efficiency, specific thrust, and specific fuel consumption are computed and compared across different cycles, providing a quantitative basis for their assessment.
