Soviet Scramjet liquid propellant engine model 5D67, 72 inches in height, on wheeled stand, weight approximately 300 lbs crated. Provenance: From the air and space collection of Professor Alexander Roudakov. The Kholod, or Hypersonic Flying Laboratory (HFL) was created as a joint effort of the Russian Central Institute of Aviation Motors and NASA. Collectively, the Kholod was an experimental rocket design for testing dual-mode scramjet engines, both air and liquid-cooled, combined with a Russian SA-5 rocket booster, for a total of 6 engines: four solid fuel boosters, the main 5D67 engine, and another scramjet in the forward part of the rocket. In 1991 the Kholod reached a maximum speed of Mach 6.47 - at the time the fastest powered flight in history (not including spacecraft operating outside the Earth's atmosphere).
