Abstract
Recent European interest in LOX/hydrocarbon propulsion systems focuses on LOX/kerosene versus LOX/methane propellants for liquid booster stages. For the preparation of a fair technical trade-off among the two propellant combinations, EADS-ST and DLR have started complementary activities addressing critical areas for the related thrust chamber development. These activities are closely coordinated, and are targeting on fundamentals such as the characterization of the propellant fluid properties, the propellant cooling characteristics, material characteristics, and ignition studies. Besides these fundamental research activities, further technology activities focusing on future application towards open and closed cycle engines have been started. This includes experimental verification of injector head designs, but also the enhancement of design tools to predict the hot gas side and coolant side heat transfer at relevant operational conditions. The technology activities finally focus on staged combustion battleship demonstrators for the coupled thrust chamber / preburner system, allowing for a fair technical trade-off between both hydrocarbon fuels.
