The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a unit in the system that supplies the liquid components of rocket propellant or the working fluid in a liquid-propellant rocket engine or the liquid fuel in certain aircraft engines, for example, ramjet engines. A turbopump consists of one or more pumps and the aircraft gas turbine that drives them. The working fluid for the turbine of a turbopump is usually formed in gas or steam-and-gas generators. Liquid-propellant rocket engines with a turbopump are used in the launch vehicles of spacecraft and in intercontinental missiles.
