L75 LOX Ethanol engine: Current status of thrust chamber and turbopump cooperative development

Resumo

In 2011, the German Aerospace Center and the Brazilian Space Agency started to cooperate in the field of liquid rocket engines. They agreed to jointly develop the L75 engine which is using Liquid Oxygen and Ethanol as propellants. Within the last year, the first hot-firing test campaign with pre-development models of the thrust chamber assembly successfully took place. Furthermore, important milestones in the development of the turbomachinery of the L75 engine, as run-in of test facilities and spin testing, have been achieved. This paper details the progress of the project, concentrating on the description of the joint activities of the consortium.
