Scientific paper
The latest Soviet heavy-lift launch vehicle, Energiya, derives much of its performance capability enhancement relative to older systems to the use of hydrogen rather than kerosene fuel in its 'sustainer' second stage; hydrogen yields three times more energy/ton than kerosene. Even the kerosene-employing first stage engines, however, have been able to set records for thrust generation on the basis of 250,000-hp turbopumps. The present account of the design features and operational procedures associated with Energiya and the Buran reusable manned vehicle gives attention to the difficulties overcome in such matters as ensuring cryogenic fuel safety at the launch site and the transportation to site and mating of Energiya with Buran.
