Abstract

Influence of primary rocket location along the flow-patch on the performance of RBCC at sea-level static was researched by CFD on an inlet-combustor combined RBCC structure. It is concluded that the influence of moving primary rocket along the flow-patch backward on intake performance is very complicated and closely bound up with the mass flow rate of primary rocket. However, moving primary rocket backward has always positive influence on the RBCC thrust and specific impulse. Moving primary rocket as backward as possible at sealevel static is recommended to maintain optimal performance of the RBCC engine.

Key words： RBCC; primary rocket; location; sea-level static; performance; influence
