Abstract
An annular diffuser for a gas turbine engine includes inner and outer walls spaced apart to define a diffuser flow path, and a support member coupling the inner wall to the outer wall while allowing independent radial displacement therebetween. The support member includes a first end portion rigidly connected to the inner wall, and a second end portion extending outside of the diffuser flowpath and coupled to the outer wall by a radially extending pin. An aerodynamically-shaped shroud member surrounds the support member to thermally isolate the support member from the diffuser flowpath, thereby shielding the support member from transient thermal loads. The shroud member is pinned to the support member at a single axial location. A combustor dome panel is attached to the downstream end portion of the shroud member and is adapted to independently support inner and outer combustor liners in spaced relation to define a combustion chamber therebetween.
