The most studied RDGT configuration is the axial one, which is particularly relevant for high-power systems. However, the specific configuration considering the coupling between a radial RDC with a radial turbine presents a great advantage in terms of compactness and could also offer an interesting potential gain of efficiency. This particular configuration will be studied here for the RDC alone and in coupling configuration with a radial turbine. Hence, a dedicated experimental setup will be installed allowing performance determination of such an integrated system. Hydrogen-air configuration will be considered to represent airbreathing applications. Pressure measurements and high-speed visualization will be performed to characterize the detonation properties. The radial RDC will benefit from the injection technology developed at ONERA by DC04 to optimize the detonation process in such specific geometry. Moreover, set up will allow for consideration of the mixing aspects between burned gas flow exiting from the RDC and a cooling/co-flow. This configuration will produce experimental reference data for the work carried out by SAFRAN (DC08) that considers ejector modelling for turbine integration. Finally, the set up will allow to identify the configuration that gives the best system efficiency.
