Hypervelocity scramjet engines promise an efficient air-breathing propulsion system with access-to-space capability. Difficulties arise when operating a scramjet engine at high altitudes and flight Mach numbers, notably above Mach 10. Oxygen enrichment is a technique proposed to augment scramjet thrust under these adverse conditions, where a small amount of oxygen is pre-mixed with the fuel before injection.
