FIELD: engines and pumps. ^ SUBSTANCE: liquid propellant engine with controlled thrust vector includes power frame, combustion chamber having head, cylindrical part and nozzle, which is fixed on power frame by means of suspension assembly providing the possibility of rolling in two planes by means of drives attached to power ring made on combustion chamber, gas generator and turbo pump unit which in its turn contains turbine, pump of oxidiser, fuel pump, gas line connecting the turbine outlet to head of combustion chamber through suspension assembly, according to invention the roll nozzles are grouped into blocks of roll nozzles in pairs and mounted on annular header installed in lower part of nozzle, which has diametre which is more than that of nozzle section; gas generator gas removal pipeline is connected to annular header, and the other end of the above pipeline is connected to gas passage; annular header is attached by means of two articulated rods to turbo pump unit and by means of two articulated rods to damper bracket installed on gas generator gas removal pipeline. Roll nozzle block contains two roll nozzles combined into one assembly; at that, pair of roll nozzles is opposite installed and equipped with three-way valve installed between them; three-way valve has the drive connected to shaft. ^ EFFECT: improved control of thrust vector and control of rocket as to roll. ^ 5 cl, 3 dwg |
