Abstract

The LUMEN project at the DLR Institute of Space Propulsion has the goal of producing a bread-board demonstrator engine powered by LOX/LNG. This paper describes the design of the baseline injection system for the LUMEN thrust chamber which uses the advance porous injector (API) concept. Numerical analysis of internal flow characteristics and acoustics of the injector used in the design phase are presented. The injection system was designed to avoid injection-coupled combustion instabilities. A prediction of the low-frequency stability characteristics is also presented.
