LIQUID ROCKET ENGINES FOR LARGE THRUST - PRESENT AND FUTURE

The possibility of an increase in economy and rise in efficiency of li quid-propellant rocket engines of launch vehicles and flight vehicles is considered. The characteristics of liquid-propellant rocket engines , made in the Soviet Union, U.S.A., France, Japan, China and other cou ntries, and working on the following fuels: O2, + H-2, O2 + kerosene, N2O4 + H2N-N(CH3)2, HNO3 + dimethylhydrazine, etc. are recalled. Ways of further improvement of liquid-propellant rocket engines are outline d and the problems, arising during their realization, are discussed.
