FIELD: engines and pumps.
SUBSTANCE: launching booster for rocket includes engine housing, nozzle with a cap, transportation and startup conveyor at the bottom of which there located is engine housing and combustion chamber in which thermoemitting element, ignition device and working medium is located. Working medium represents liquid material forming superheated steam during combustion of thermoemitting element. Thermoemitting element is made from thermit mixture in the form of hollow tube with walls of cyclically variable thickness and covered on all sides with thin-wall metal with high heat conductivity. Inside combustion chamber coaxially to thermoemitting element there located is heat resistant tube having the length equal to the length of thermoemitting element. Pump with drive for supply of working medium to lower part of combustion chamber to thermoemitting element is located immediately above engine housing; at that, smaller part of working medium returns from pump to hollow cavities of tanks for their wetting.
EFFECT: higher reliability of launching booster.
