A RBCC engine is applicable in a reusable spacecraft such as the first stage of the two stages to orbit Tengyun space plane.

Is this the Tengyun space plane?

Application in SSTO space plane, it will take off horizontally from an airfield, rocket + ramjet take it to Mach 2+, then operating in turbine + ramjet in Mach 5+, then liquid fuel rocket accelerate it from Mach 10+ to Mach 25+ to enter orbit. Re-entry takes the form of unpowered glide. Once in atmosphere, it operate in powered flight with the RBCC engine to land horizontally.

Another application is in a twin engine SSTO HTHL spacecraft.
