Abstract

The variable inlet concept was proposed based on the rocket-based combined cycle engine (RBCC). The flow field characteristics and performance parameters of the variable inlet concept were obtained by numerical simulations. The influence of inlet throat height on compression level and the influence of compression level on combustor performance were analyzed in detail at Ma=5.0. The results show that: the variable inlet concept provides the desired cycle static temperature ratio in ramjet mode and scramjet mode and possesses a proper starting Mach number which meeting the demand of mode transition in ejector mode. What’s more, the results also show that the inlet throat height imposes evident influence on the compression level, while the compression level imposes evident influence on the combustor performance.
