A gas-turbine engine comprises an axial multi-stage compressor, a turbine and body of the back bearing with communications that connects those, they go under tubular-circular counter-flow combustion chamber. Communications are placed in tube space, are concentric pipes, the inner pipe is communication one, the outer is screening one, cavities between those are connected to atmosphere at whole length. A method for assemblage of gas-turbine engine consists in that communications are assembled and one checks tightness of those out of gas-turbine engine, vertical and inclined parts of communication pipe are welded together, one checks tightness of welded joint, to communication pipe one mounts vertical and inclined parts of screening pipe, one welds those, after that one welds together communication and screening pipes, with check of tightness of welded joints. |
