FIELD: engines and pumps.
SUBSTANCE: multistage booster-rocket contains central block of the first stage with side rocket blocks and central block of the second stage with side rocket blocks of the second stage, at that all the blocks have housing, tanks of oxidant and fuel inside housings and at least one liquid propellant rocket engine in each rocket block. Also there are roll nozzle blocks containing two roll nozzles oppositely installed, at that roll nozzle blocks are installed on external surface of housings of side rocket blocks of all the stages distant from axis of booster-rocket. Even number of side rocket blocks of the first stage was analysed, roll nozzle blocks of the first stage are installed on two diametrically opposed side rocket blocks of the first stage. Odd number of side rocket blocks of the first stage was analysed, roll nozzle blocks of the first stage are installed on all side rocket blocks of the first stage. Number of side rocket blocks of the second stage corresponds to number of side rocket blocks of the first stage. Proposed liquid propellant rocket engine includes power frame, combustion chamber with head, cylindrical part and nozzle, the chamber is fixed on power frame by suspension assembly providing movement in two planes; also it includes gas generator and turbo-pump unit containing turbine, oxidiser pump, fuel pump, gas line connecting the outlet of turbine to head of combustion chamber through suspension assembly; at that, roll nozzles are grouped into roll nozzle blocks in pairs and installed on lower power ring installed in lower part of nozzle and connected to nozzle section, pipelines of gas-generator gas delivery are connected to roll nozzles via three-way valves of gas and fuel, the other ends of pipelines are connected at first to pipeline of gas removal and fuel pipelines, at that roll nozzles blocks are fixed on lower power ring by two inclined rods. Roll nozzles block contains two nozzles installed oppositely and combined in one assembly containing common housing, at that a pair of roll nozzles is equipped with three-way valves of gas and fuel installed between roll nozzles and having common drive.
EFFECT: improved control of thrust vector and control of rocket as to roll.
