A scramjet inlet compresses the flow from Mach 8 to Mach 3 at the combustor entry. The flow remains
Answer: A
Correct answer: Supersonic throughout
Mach 3 at the combustor entry is supersonic, so the flow has been compressed but never brought below sonic speed - that is the definition of scramjet operation. The inlet is a series of oblique shocks and compression surfaces with no normal shock and no throat that would force the flow subsonic. Keeping it supersonic is what keeps the static temperature within reach of the structure and of useful combustion chemistry.
