    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.

    摘要: A tank comprises a structural envelope made in a form of hemisphere with a tube connection having a ring groove in its surface. A tightening ring of the structural envelope. An elastic diaphragm made in a form of hemisphere integrated with a cylinder provided with an end projection that fits into the ring groove. A bottom is made in a form of a sphere part. A thin-walled ring with a shoulder is introduced that is mounted between the tightening ring and elastic diaphragm in the place of its end projection location. The tube flange is provided with an end projection. The tightening ring is equipped with a lateral flange providing a possibility for the thin-walled ring shoulder tightening by it to the ring projection of the tube flange. The external surface of the tightening ring and internal surface of the tube flange are made tapered in the direction from the ring groove to the hemisphere of the structural envelope above the ring groove. The bottom is made to be hollow and its' internal surface is provided with holes. A splitter is introduced that is mounted in the bottom space.

    摘要: A device comprises a bellows with protective rings arranged between corrugations of the bellows. Support rings are connected in a sealed manner to a gas line and a combustion chamber. A gimbal ring is positioned outside the bellows and via hinges is connected to structural brackets with support rings. A shield is mounted inside the bellows, the shield consisting of two cylindrical envelopes telescopically inserted one in another with a gap. The cylindrical envelopes are fixed in cantilever to support rings, forming a chamber which via channels for feeding a cooling working medium made in the support rings is connected to a main line for feeding the cooling working medium, and via the gap between the envelopes—to the cavity of the bellows unit. A housing is arranged outside the protective rings and adjoining them, and is made in the form of a metallic cylindrical helix, the ends of which are connected to the support rings (FIG. 2).

    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.
