  • the first and second annular walls can be assembled by welding, axial interlocking or bolting. Joining by welding makes it impossible to dismantle the first and second walls, for example for maintenance or for the replacement of one of these walls.
  • the assembly by axial interlocking has the disadvantage of not being sealed, combustion gases can escape through the fitting areas of the first and second annular wall.
  • the assembly by bolting has the disadvantage of promoting the appearance of cracks and fissures in the vicinity of the bolt screw engaging holes, which weakens the combustion chamber.

  • first and second complementary assembly means are nested or engaged with each other by rotating them relative to each other around the axial direction of the combustion chamber.
  • azimuthal engagement makes it possible to reduce the leakage of combustion gases with respect to an axial engagement. Since radial thermal expansion is less important than axial thermal expansion, an azimuth interlocking connection makes it possible to maintain permanent contact between the first and second annular walls, thus ensuring reduced or zero gas leaks under all conditions. of uses of the combustion chamber. In addition, such azimuthal interlocking makes it possible to use reduced or even zero clearance compared to an axial interlocking. Moreover, the interlocking of the first and second annular walls makes it possible to disassemble them.

This makes it possible to improve the mechanical strength of the assembly and to reduce the leakage of combustion gases.
