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
ethylene­oxygen mixtures have revealed detonation modes with one, two and three separate detonation
heads, depending on mass flow rate. Spectrograms from high­frequency pressure data and high­speed
photography are used to confirm successful operation and identify the operational modes reliably.
