Which outcome limits scramjet performance at high Mach?

💡 Explanation

Decreased combustion efficiency limits scramjets because supersonic airflow inhibits flame holding; therefore, injected fuel may exit uncombusted due to insufficient residence time for complete oxidation rather than effective energy conversion.
