    摘要： The invention relates to rocket engine manufacturing, and may also be used in aircraft engine manufacturing. A chamber comprises a casing, ignition means and a mixing head. The mixing head consists of an internal injector face, a middle bottom, an external bottom. Bipropellant injectors are fixed in the internal injector face and the middle bottom. A portion of the bipropellant injectors are mounted projecting from the internal injector face, while another portion are recessed in the internal injector face. The ignition means are made from jet injectors mounted in a structural casing behind the internal injector face. Axes of diverging ports of jet injectors are positioned at an acute angle to an outlet from the structural casing and deflected in a circle in a lateral plane from the longitudinal axis of the structural casing in an identical direction. The chamber casing comprises a combustion chamber and a nozzle, made from an external structural envelope and an internal fire wall. A regenerative cooling passage is positioned between the external structural envelope and the internal fire wall. A ring-like slot of a gas-screen belt is made in the internal fire wall before the nozzle throat. The regenerative cooling passage of the chamber is made with a branched inlet. One of its branches communicates with the space of the chamber regenerative cooling passage between the nozzle throat and its scarf, a second branch—with the space of the chamber regenerative cooling passage before the nozzle throat, and a third—with the space of the chamber regenerative cooling passage before the ring-like slot of the gas-screen belt.

    摘要： The liquid-propellant rocket engine comprises two combustion chambers, a gas generator, a turbopump assembly, pipelines as well as a frame having footpads and supports located in different planes that are perpendicular to the engine axis, said frame being made up of at least two welded rod sections. Said sections are fastened to each other by a plane rod joint. The engine pipelines are connected to the combustion chambers and comprise bellows balances or flexible hoses which have their movable ends connected directly to the combustion chambers or to pipes joined thereto. The frame is made demountable due to the use of threaded connections that joint together the frame sections and the plane rod joint. The frame is made as a compensation frame by placing the footpad plane over the support plane. A curved pipe joint comprises a curved pipe, a hinge and a frame. At its end on the outlet side, the pipe is provided with a balance for compensating angular displacements, for instance, a bellows balance with a cardan mechanism. The curved pipe is connected to the frame by a hinge, and its outlet end is gas-tightly connected to the bellows of the balance.

    摘要： The engine comprises a chamber, fuel and oxidizer booster pumps, a turbopump unit, a gas generator, an electrically driven thrust regulator, and a fuel throttle. A programmable starting and ignition system is introduced, which includes a fuel tank, connected to the thrust regulator, and a first ampoule with starting fuel, an output of which through a starting/cut-off valve is connected to fuel injectors of the gas generator. The aforesaid tank is also connected through a second ampoule to the starting fuel and by a jet to autonomous ignition injectors located in the space of the combustion chamber of the engine. An inclined Archimedian screw pump with a gas turbine as an actuator and an oxidizing gas as a working medium is used as an oxidizer booster pump. The gas is discharged after its use in a turbine into an outlet manifold of the booster pump. A heat exchanger, in which the gas used for rocket tank pressurization is heated, is mounted on a pipeline feeding the gas to the aforesaid gas turbine of the booster pump actuator.

    摘要： A method includes the round billet skelping, several runs of each round billet drawing up to a given size, packing the drawn billets into a multilayer bank, corrugating the bank with the bellows formation as a result and its heat treatment. Each round billet is skelped of the age-hardenable nickel alloy containing components of the following group: niobium, aluminum, titanium, tungsten and molybdenum. Each round billet is drawn, heated up to the temperature of 1000-1130° C., held in the shielding medium at the above temperature, and cooled down, after that the above operations of drawing, heating, holding and cooling are repeated until the given size of each round billet is reached. The drawn round billets are packed into the multilayer bank and the bank is corrugated for forming the multilayer bellows. The heat treatment of the bellows is made by its heating up to the temperature of 1000-1130° C., holding in the shielding medium at this temperature until the strengthening phase is completely dissolved in the alloy and subsequent cooling down to the temperature of the phase transition termination in the alloy. A rarefied air medium or argon are used as the shielding medium.
