Abstract

See full text

The invention concerns a gas turbine engine component (27) comprising an outer ring (21), an inner ring (20), a plurality of circumferentially spaced elements (22) extending between the inner ring (20) and the outer ring (21), wherein a primary gas channel for axial gas flow is defined between the elements (22), wherein the component (27) has an inlet side for gas entrance and an outlet side for gas outflow, and an annular load transfer structure (23) positioned internally of the inner ring (20) for transferring loads between said elements (22) and a bearing structure (24) for a turbine shaft (11) positioned centrally in the component (27), wherein the annular load transfer structure (23) extends circumferentially along at least a part of an inner side of the inner ring (20) and inwards in a radial direction of the component (27), wherein the annular load transfer structure (23) has a first portion (23a) and a second portion (23b), and wherein the first portion (23a) is located closer to the inner ring (20) than the second portion (23b). The invention is characterized in that the first portion (23a) is radially inclined between a first position (30) in the vicinity of the inner ring (20) and an axially displaced second position (31) and wherein the second portion (23b) extends from the second position (31) and is inclined in relation to the first portion (23a), and wherein the annular load transfer structure (23) is provided with a plurality of circumferentially spaced load carrying members (32) arranged at a side of the first portion (23a) axially facing in a direction towards the second position (31), wherein the load carrying members (32) are arranged to form a load carrying connection between the annular load transfer structure (23) and said elements (22) via the inner ring (20). The invention also concerns a gas turbine engine (1) comprising a component (27) of the above type.
