Associated Engines
  • RD-012U Bondaryuk ramjet engine. 76 kN. Burya. Out of production. 1.2 m diameter ramjet to be used in Burya cruise missile. Thrust is maximum thrust at cruise altitude. Specific impulse is that at cruise design point. Isp=1500s. First flight 1957. More...

Associated Launch Vehicles
  • Burya A government decree on 20 May 1954 authorised the Lavochkin aircraft design bureau to proceed with full-scale development of the Burya trisonic intercontinental cruise missile. Burya launches began in July 1957. The project was cancelled, but the team was allowed final tests in 1961 that demonstrated a 6,500 km range at Mach 3.2 with the 2,350 kg payload. In cancelling Burya the Russians gave up technology that Lavochkin planned to evolve into a manned shuttle-like recoverable launch vehicle. 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...
