Abstract: Enabling high overall pressure ratios (OPR), wave rotors, and piston concepts (PCs) seem to be solutions surpassing gas turbine efficiency. Therefore, a comparison of a wave rotor and three PCs relative to a reference gas ...

Abstract: Fair comparison of future aircraft engine concepts requires the assumption of similar technological risk and a transparent book keeping of losses. A 1000 km and a 7000 km flight mission of a single-aisle airplane similar ...
