FIELD: engines and pumps.
SUBSTANCE: liquid-propellant engine consists in power frame, combustion chamber that can swing in two plane surfaces, gas generator and turbo-pump unit connected to gas generator by means of gas passage. Gas passage in its turn includes turbine, oxidiser pump, fuel pump and additional fuel pump, gas passage that connects turbine output with combustion chamber. According to invention combustion chamber is pivoted to power frame with the possibility of swinging in two plane surfaces. The engine is equipped with two pairs of roll nozzles that are connected to gas pipelines coming from gas passage. Turbo-pump unit is connected to frame by means of rods. Below combustion chamber lower cut there concentrically installed is strong ring with diametre larger than combustion chamber lower cut. The ring is connected with roll nozzles that are connected with gas-pipelines coming from gas passage and fuel pipelines. The other ends of fuel pipelines are connected to fuel pump output. The output of fuel pump through bellow is connected to combustion chamber main manifold. Turbo-pump unit is reviewed.
EFFECT: improvement of thrust vector control.
