TīmeklisRamjets have a velocity range of 1 to 6 Mach in theory, but Scramjets have a range of 12 to 24 Mach in theory. Because ramjets and scramjets can’t produce thrust at zero velocity, they need a lot of airflows to start started. Scramjets have a higher specific impulse than Ramjet. Owing to subsonic combustion, Ramjet has greater efficiency … Tīmeklis2024. gada 23. sept. · Ramjet facts for kids. A ramjet is a type of engine which uses the properties of air to create thrust.
