Design and testing of a low mass flow RDE running on ethylene-oxygen
Design and testing of a low mass flow RDE running on ethylene-oxygen
A modular laboratory rotating detonation engine (RDE) for combined mass flow rates below 10 g/s has been designed. Since a large chamber diameter to width ratio is used, first tests with stoichiometric ethylene-oxygen mixtures have revealed detonation modes with one, two and three separate detonation heads, depending on mass flow rate. Spectrograms from high-frequency pressure data and high-speed photography are used to confirm successful operation and identify the operational modes reliably.

Abstract
A modular laboratory rotating detonation engine (RDE) for combined mass flow rates below 10 g/s has been designed. Since a large chamber diameter to width ratio is used, first tests with stoichiometric ethylene-oxygen mixtures have revealed detonation modes with one, two and three separate detonation heads, depending on mass flow rate. Spectrograms from high-frequency pressure data and high-speed photography are used to confirm successful operation and identify the operational modes reliably.
