Abstract: For atmospheric flight at speeds above Mach 3, and even for M < 3 for unmanned vehicles, the most promising propulsion systems are ramjets and air-augmented rockets. Many ramjet-powered vehicles have been developed (see, e.g., Refs. 1–3), including a successful experimental turbo-ramjet airplane [4]. Three operational ramjet missiles have been deployed: Talos (still in the United States Fleet), Bomarc, and the British Bloodhound. Air-augmented, solid-propellant rockets are simpler than ramjets and should be as good or better for some applications, and air-augmented liquid rockets offer versatility in thrust/specific-impulse tradeoffs during flight. Still simpler is the “external burning ramjet,” which employs combustion over an external surface and could be used for range extension or side forces on simple bodies. For hypersonic propulsion, ramjets with internal supersonic combustion (scramjets) show great promise (see also Chapter 14).
