摘要:
The invention relates to a device for injecting an air/fuel mixture into a combustion chamber, which is to be mounted within a restricted space. This injection device (20) comprises a bowl (70) having an external cylindrical wall (73) continued at its downstream end by a divergent section (74) provided, downstream, with a collar (75) having the form of a ring extending radially outward, the divergent section of the bowl being connected, immediately upstream of the flange, by a connecting wall (76) to a cylindrical ring (77), the cylindrical ring and the connecting wall forming a connection rim oriented in the upstream direction. At least one row of vortex holes (79) is formed in the external cylindrical wall, close to its upstream end, and the connecting wall of the connection rim of the bowl is provided with a row of cooling orifices (81) inclined axially at an angle y to the axis of symmetry of the injection device.

The present invention relates to a baffle (10) for the bottom of a combustion chamber of a gas turbine engine, comprising a flat portion of wall (10a) with an opening for an injector of the combustion chamber to pass through, two longitudinal edges (10c, 10d) for the assembly to two adjacent baffles and two transverse edges (10e, 10f), wherein at least one of the edges comprises a joint cover (10d1) arranging a housing (10d10) along said edge for an edge (10′c) of an adjacent baffle (10′) so as to seal the junction between the two edges. The invention also relates to a combustion chamber incorporating said baffles.

摘要:
A turbomachine including an annular combustion chamber, the combustion chamber presenting a connection flange at its downstream end for connection to an outer casing. The connection flange bears axially against the outer casing and is blocked in an axial direction by the upstream end of an inner casing of a high pressure turbine.
摘要:
A gas turbine engine combustion chamber including at least one deflector mounted on the chamber end wall and including an opening for a carburetted air supply device. The deflector includes an opening, corresponding to the chamber end wall opening, with an annular cylindrical part for attachment to the wall, the cylindrical part including a mechanical attachment mechanism collaborating with a complementary attachment mechanism on a metal sleeve secured to the wall and a cylindrical centering cup fixed by one end to the sleeve and housed inside the cylindrical part of the deflector.
摘要:
A turbomachine combustion chamber including a substantially L-shaped fuel injector and a device for mounting and fastening the injector in an orifice of the casing of the chamber, is disclosed. The device includes an outer collar carried by the injector and a removable annular spacer surrounding the injector and designed to be interposed between the collar of the injector and the casing.
