Associated Engines
  • XRJ47-W-5 Wright ramjet engine. 33.4 kN. Out of production. Thrust is maximum thrust at cruise altitude. Specific impulse is that at cruise design point. Isp=1200s. Used on Navaho G-26 launch vehicle. First flight 1956. More...

Associated Launch Vehicles
  • Navaho G-26 American intermediate range cruise missile. The Navaho G-26 was a 2/3 scale test version of the operational Navaho G-38. The Navaho program was cancelled on 13 July 1957, but already-built G-26 test missiles were flown to the end of 1958. More...

Associated Propellants
  • Air/Kerosene Ambient air (78 % nitrogen, 21% oxygen, etc.) is scooped up by air intakes and used in turbojet, turbofan, ramjet, scramjet, or other airbreathing engines. It is used to burn aviation-grade kerosene, commercial grade JP-4 or JP-5, their military equivalents, or special high-temperature blends such as those used in the SR-71. More...
