The design of the injector head is a crucial factor in the design process for future LOX/kerosene rocket engines. Different injector configurations were investigated in a single-element subscale rocket combustion chamber. Recorded data of static wall pressure and heating of the cooling fluid allow for the assessment of characteristic parameters. The influence of combustion on the element’s pressure drop was investigated with a comparison of spray test data with measurements made during hot fire tests. For the different configurations, the influence of a design change on the distribution of heat release, heat transfer and the combustion efficiency were characterized. The insights gained allow for a tailored design of the injector head of an oxidizer rich staged combustion cycle rocket engine. Furthermore, the data recorded represents a board database for the validation of numerical simulation tools.
