Associated Engines
  • NK-231 Kuznetsov turbofan engine. 226.5 kN. Tu-160. Development ended 1992. Turbofan engine used in Tu-160. Thrust is maximum sea level thrust; specific impulse is sea level value at that thrust. Isp=1980s. More...

Associated Launch Vehicles
  • Burlak Russian air-launched winged orbital launch vehicle. Burlak air-launched satellite launcher was proposed in 1992 and studied by Germany in 1992-1994. Evidently based on secret anti-satellite missile. Air launched from Tu-160 bomber, released at 13,500 m altitude and Mach 1.7. Development estimated to cost only DM 50 million, but not proceeded with. Burlak/Diana variant would have been launched from Concorde. 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...
