Abstract (en)
[origin: EP3255344A1] A combustion chamber arrangement (15) comprises an annular outer wall (50) and an annular inner wall (52) comprising at least one row of tiles (52A). Each tile in the row of tiles (52A) has a rail (53) extending towards and sealing with the outer wall (50) and a lip (63) extending in a downstream direction from the row of tiles (52A). The outer wall (50) has a row of apertures (57) to direct coolant onto the lips (63) of the row of tiles (52A). Each tile (52A) has a fastener (72) positioned upstream of the rail (53) and the fastener (72) extends through a corresponding mounting aperture (70) to secure the tile (52A) to the outer wall (50). The rail (53) of each tile (52A) defines a plurality of slots (86) with the outer wall (50) and the slots (86) are arranged in a region (84) downstream of the corresponding fastener (72). None of the apertures (57) in the row of apertures (57) are arranged in a region (90) downstream of the fastener (72) of the tiles (52A). The arrangement reduces crack generation and propagation in the outer wall (50).
