摘要

1. The deflector of the bottom of the combustion chamber of a gas turbine engine, comprising a wall portion with an opening for the passage of the injector of the combustion chamber, two longitudinal ribs and two transverse ribs, characterized in that at least one of the longitudinal ribs contains a butt strip forming a seat along the aforementioned ribs for a corresponding longitudinal protrusion or ribs of an adjacent deflector to seal the connection between the two ribs and to allow their mutual sliding with volume expansion of the wall of the bottom of the combustion chamber. ! 2. The deflector according to claim 1, in which the seat is formed by a ledge of the wall. ! 3. The deflector according to claim 1, in which the seat is formed by a recess. ! 4. The deflector according to claim 1, in which the transverse ribs contain part of the curved wall, while the seats are placed evenly along the longitudinal ribs of the curved part. ! 5. The deflector according to claim 1, comprising a joint strip along a longitudinal rib and a longitudinal rib without a butt strip along another longitudinal rib, both ribs being complementary for connecting to the rib of another deflector of the same adjacent position. ! 6. The deflector according to claim 1, containing a butt strip along both longitudinal ribs. ! 7. The deflector according to claim 6, containing two longitudinal ribs complemented by butt planks. ! 8. The combustion chamber of a gas turbine engine, made annular and containing an outer wall, an inner wall, a wall connecting the two walls and forming the bottom of the chamber, baffles, according to claims 1 to 7, from containing a part of the wall parallel to the bottom of the chamber and inserted into the bottom. ! 9. The combustion chamber of a gas turbine engine, made
