摘要： A gas generator is produced of separate units, including a mixing head, a casing and an outlet branch pipe, which are interjoined by welding. The mixing head is welded to the outlet branch pipe through a spacer and a structural spherical casing. The spacer and the outlet branch pipe are made of two inter-brazed envelopes, the inner envelopes of the spacer and the branch pipe are welded at their end faces by electron-beam welding, and the outer structural envelopes are welded by electron-arc welding using a split ring. The spacer is joined to the mixing head by automatic gas-shielded welding. The spherical casing of the gas generator is welded to the outlet branch pipe and the mixing head after the spacer is welded to the mixing head and the outlet branch pipe.

摘要： A combustion chamber for a liquid-propellant rocket engine includes an injector head jointed to a combustion chamber casing having an exhaust head on a nozzle output. The casing is made of a steel jacket and a bronze-steel internal fire wall, which are joined with each other and contain shells connected in series. The exhaust head with shells of the casing, jointed to the exhaust head, are brazed using a solder on the basis of nickel, chromium and manganese. Parts of the injector head and other members of the combustion chamber casing are brazed using a copper-silver solder. Shells of the fire wall are connected by an electron-beam welding, directing an electron beam into axial gaps left while brazing between shells of the jacket. The shells of the jacket are then sequentially connected by an automatic gas-shielded arc welding through corresponding ring spacers.

摘要： The invention relates to the field of producing the means for protecting the alloys on the nickel base against the influence of corrosive media, and more particularly concerns the metal-ceramic coatings used for protecting the flow parts of the turbines of turbopump liquid-propellant rocket engines (LRE). The composition for producing the metal-ceramic coating consists of nickel and of oxides of barium, boron, aluminum, cerium and zirconium at the following percentage of components by mass: nickel--36-58, barium oxide--16-19, boron oxide--7-13, aluminum oxide--6-9, cerium oxide--14-19, zirconium oxide--1-2. The coating is produced of a slip, that is applied to the pieces by dipping, spraying or flooding. The slip layers are dried in the flow of hot air. The coating is fired in a furnace in the inert gas medium, argon for example, at a temperature of 1000-1100.degree. C. during 0.5-1 hour. The use of the composition for producing a metal-ceramic coating for the pieces and units of complicated shape made of nickel alloys with a layer of nickel secures their serviceability and reliability at a cyclic action of a high-temperature flow of oxidizing generator gas containing the particles of AMg6 alloy at the temperature of up to 900.degree. C.
