Abstract
An outer housing for supporting a stator assembly in a gas turbine engine, wherein the support includes two outer ring sections between which the vane segments of the stator assembly are mounted to form a ring within the cylindrical support. A central ring section is provided between the outer ring sections and is connected thereto by means of spokes. The central ring section locates the structure within the engine casing. The spokes extend at an angle to the axis of the stator assembly and define openings therebetween whereby thermal distortion between the outer rings and the central ring is attenuated.
Claims13
A cylindrical support structure for use in a stator assembly in a gas turbine engine having an engine casing, the support structure having:
- two outer ring sections between which vane segments of the stator assembly will be mounted to form a ring within the support structure;
- a central ring section by means of which the support structure will be radially located within the engine casing;
- and connecting means extending between the outer ring sections and the central ring section, the connecting means constructed to attenuate thermal distortion transmitted between the outer ring sections and the central ring section.
A stator assembly in a gas turbine engine having an engine casing, the assembly comprising a plurality of stator vane segments abutting to form a stator ring and a generally cylindrical support structure within which the vane segments are assembled to form the stator ring;
- the support structure having two outer ring sections between which the vane segments are mounted and a central ring section by means of which the support structure is radially located within the engine casing;
- and connecting means extending between the outer ring sections and the central ring sections, the connecting means constructed to attenuate thermal distortion transmitted between the outer ring sections and the central ring section.
