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.

Gas turbine engine component

A turbine including a rotor () that is driven by gas and that has a housing () enclosing the rotor. The turbine includes a component () suspended from the housing () that is arranged inside the housing () and at least partially beside the rotor () with respect to the direction () of the gas flow in order to impede any fragments which may come loose from the rotor from penetrating the housing in radial direction.
