A gas turbine combustor wall element for attaching to an outer wall of a gas turbine combustor, the wall element comprising:
- a ceramic body for defining part of an inner wall of the gas turbine combustor;
- and
- a support contained by the ceramic body, said support having one or more serpentine ligaments extending from a location within the ceramic body, and having an attachment element joined to the serpentine ligaments and extending from the location in a direction perpendicular to the serpentine ligaments and protruding outward from the ceramic body for securing the ceramic body to the outer wall.
A turbine engine comprising:
- a turbine;
- a compressor connected via a shaft to the turbine;
- a main fuel supply line for supplying fuel;
- and
- a combustor positioned for receiving the fuel and for releasing hot expanding gases to the turbine, said combustor including a gas turbine combustor wall element for attaching to an outer wall of a gas turbine combustor, the wall element comprising:
- a ceramic body for defining part of an inner wall of the gas turbine combustor;
- and
- a support contained by the ceramic body, said support having one or more serpentine ligaments extending from a location within the ceramic body, and having an attachment element joined to the serpentine ligaments and extending from the location in a direction perpendicular to the serpentine ligaments and protruding outward from the ceramic body for securing the ceramic body to the outer wall.
