THERMALLY COMPLIANT SUPPORT FOR A COMBUSTION SYSTEM

Title:

THERMALLY COMPLIANT SUPPORT FOR A COMBUSTION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2012/161905

Kind Code:

A3

Abstract:

A support structure in a gas turbine combustor end cap (24) including a bracket (60) with a first leg (61) and a second leg (62) forming a generally trapezoidal geometry. Each leg has a first end (61A, 62A) attached to an inner concentric ring (46), and a second end (61B, 62B) attached to a crossbar (65). The crossbar is attached to an outer concentric ring (48). A circular array of such brackets interconnects the two concentric rings (46, 48). Each leg has at least one curved middle portion (63, 64), such as an arcuate or sinusoidal curve at a midpoint on the length of each leg. This shape provides flexibility in a radial direction that accommodates differential thermal expansion of the concentric rings while providing a rigid connection in an axial direction.
