Abstract
A wall structure for a gas turbine combustor arranged to have a general direction of fluid flow therethrough includes inner and outer walls defining a space therebetween. The inner wall is made up of a plurality of tiles having axial edges aligned generally with the direction of fluid flow, a gap being defined between axial edges of adjacent tiles. Orifices are provided within the axial edges to direct leakage air passing through the gaps to give the leakage air a flow component in the general direction of fluid flow through the combustor.

A wall structure for a gas turbine engine combustor arranged to have a general direction of fluid flow therethrough, the wall structure including inner and outer walls, the inner and outer walls defining a space therebetween, wherein the inner wall includes a plurality of wall elements, the plurality of wall elements include axial edges, the axial edges being aligned generally with the direction of fluid flow, a gap being defined between adjacent axial edges of adjacent wall elements, and wherein means are provided for directing leakage air passing through the gaps such that the leakage air has a flow component in the general direction of fluid flow through the combustor.
A wall element for use as part of an inner wall of a gas turbine engine combustor wall structure including inner and outer walls, the inner and outer walls defining a space therebetween, the wall element including axial edges, the axial edges aligned in use with a general direction of fluid flow through the combustor, wherein the wall element includes means associated with the axial edges for directing leakage air passing around the axial edges such that the leakage air has a flow component in the general direction of fluid flow through the combustor.
