N2 - Results of theoretical investigations on expander bleed cycle engines as well as operational experience with the LE-5B rocket motor are described. Based on results of an earlier cycle analysis, an improved engine variant of a high thrust, cryogenic bleed cycle engine is analyzed. Its performance is calculated, and a preliminary engine sizing and mass analysis is carried out. Improvement options as well as growth potential of the cycle is investigated. Special attention is paid to the critical heat-transfer in the thrust chamber region. Finally, an ascent trajectory optimization and an assessment of the complete vehicle are performed to evaluate the engine as part of a future semi reusable launch system.
