Abstract
The invention concerns a gas turbine engine component () comprising an outer ring structure (), an inner ring structure () and a plurality of circumferentially spaced radial elements () for transferring loads between the inner ring structure () and the outer ring structure (), wherein the outer ring structure () comprises a circular ring member () for withstanding an internal pressure during operation of the gas turbine engine. The invention is characterized in that the outer ring structure () comprises a first set of circumferentially distributed and substantially straight reinforcement ribs () for achieving radial stiffness, wherein the reinforcement ribs () form sides in a polygonal shape and wherein each of said reinforcement ribs () extends between two adjacent radial elements (). The invention also concerns a gas turbine engine () comprising a component () of the above type.
