A composite cycle engine (CCE) is an air-breathing jet engine that combines the power density of turbomachinery with the thermal efficiency of a piston engine. The present work investigates the synergies of combining the CCE with hydrogen fuel. A system level model is presented and used to estimate the performance of a short-medium range aircraft engine, focusing on fuel burn and emissions.
