Abstract
Analysis of rocket jet and secondary combustion to thermal environment on pylon under high thermal load was carried out for RBCC engine at Mach 5.5 with different operating mode and active thermal scheme was designed. At the rocket-scramjet mode, pylon was heated by rocket plume and secondary combustion whose thermal environment was the most serious which presents a trend of "high-low-high" in the direction of flow because the protection of film formed by fuel injection. Based on rocket-scramjet working mode, comparing three kinds of channel layout found that increasing number of channels and flow rate would improve cooling effect at severe highly heated parts and uniformity of temperature distribution which kept the engine work stably for a long time. Adopting kerosene after cooling makes engine thrust increase 1.5%.
