FIELD: engines and pumps.SUBSTANCE: transition duct for connection of a combustion chamber and a turbine part of a gas turbine engine comprises a shell including the first and second surfaces. The first and second surfaces of the shell are connected by piercing, and the shell of the transition duct is made at least from one sheet stamped into a shape that creates a transition duct with a double shell. The other invention of the group relates to a gas turbine engine comprising the above transition duct. When the above transition duct is manufactured, the shell is produced, which comprises the first and second surfaces, and connection is made by piercing to connect the specified surfaces.EFFECT: group of inventions makes it possible to simplify manufacturing of a transition duct.12 cl, 10 dwg |
