Wall elements for gas turbine engine combustors
First Claim
1. A wall element for a wall structure of a gas turbine engine combustor with the engine having a principal axis, the wall element comprising a base portion having an axis which in use, extends generally parallel to the principal axis of the engine, wherein the dimension of said wall element parallel to said axis thereof is greater then substantially 20% of the dimension of the wall element transverse to said axis of the wall element, and the base portion includes a plurality of rows of mixing ports to allow gas to enter the combustor in use.

Abstract
A wall element (29A, 29B) for a combustor (20) of a gas turbine engine (10). The wall element (29A, 29B) defines an axis. In use, the axis is arranged generally parallel to the principal axis of the engine (10). In one aspect, the length of the wall element (29B) along the axis is at least substantially 20% of the length of the wall element (29B) transverse to the axis. In another aspect, the wall element (29A, 29B) has a first pair of opposite edges extending transverse to the axis and a second pair of opposite edges (48, 50) extending transverse to the first pair, at least one of the second pair of edges (48, 50) being angled relative to the axis of the wall element (29A, 29B).
