FIELD: engines and pumps.
SUBSTANCE: proposed engine with controlled thrust vector comprises housing, combustion chamber that has head, cylindrical section and nozzle. Said combustion chamber is secured in housing by means of suspension to be swung by drives in two planes. Engine comprises also gas generator and turbo pump. The latter comprises turbine, oxidiser fuel pumps, gas line to communicate via bellows and by branch pipe on combustion chamber head. Note here that gas generator is secured to housing by hinge. Turbo pump is attached the housing by, at least, two articulated tie rods. Gas line, compensator with tube and flange and branch pipe are aligned and have spherical joints with their inner parts being made integral with tube flanges. In compliance with the invention, Note here that gas generator is secured to housing by hinge. Turbo pump is attached the housing by, at least, two articulated tie rods. Suspension assembly is made up of spherical hinge joint arranged at combustion chamber head top. Spring thrusting against flanges is arranged concentric with the tube. Guide vanes are arranged inside combustion chamber head. Suspension assembly comprises outer fixed part rigidly secured to the housing and inner moving part rigidly secured to combustion chamber head. In compliance with this invention, said parts form spherical articulated joint with spherical sealing surfaces. Note here said outer fixed part is made up of two, top and bottom, parts bolted together via shim.
EFFECT: higher reliability of LPRE combustion chamber suspension, simplified design.
