"In order for the scramjet engine to ignite,..."
- HPsquared 5y agoThese engines (ramjets, including scramjets - the 'sc' means supersonic combustion, which is the hard part) rely on forward airspeed to compress the air as it enters the engine. You can't have a ramjet without some sort of booster stage (or non-ramjet mode of operation). In this case, there's probably a conventional rocket engine to get it up to speed, which is then sustained by the (sc)ramjet engine.
