Transition support system for combustion transition ducts for turbine engines
First Claim
1. An adjustable transition duct support system for a transition duct that channels hot gases from a combustor exit to a gas turbine inlet of a turbine engine, comprising:
- a transition duct body formed from an outer wall that forms an internal passage extending between an inlet and an outlet of the transition duct body;
an adjustable forward transition flexible support assembly in contact with the transition duct body, wherein the forward transition flexible support assembly is formed from a base extending toward the transition duct body, and a first side support arm and a second side support arm extending from the base to the transition duct body;
wherein the first side support arm is formed from a plurality of first side flex plates spaced from each other with spacers, wherein the first side flex plates provide rigidity in circumferential and radial directions and flexibility in an axial direction; and
wherein the second side support arm is formed from a plurality of second side flex plates spaced from each other with spacers, wherein the second side flex plates provide rigidity in circumferential and radial directions and flexibility in the axial direction.

Abstract
An adjustable transition duct support system for a transition duct that channels hot gases from a combustor exit to a gas turbine inlet of a turbine engine. The adjustable transition duct support system includes an adjustable forward transition flexible support assembly in contact with a transition duct body, whereby the forward transition flexible support assembly may be formed from a base extending toward the transition duct body and first and second side support arms extending from the base to the transition duct body. The first and second side support arms may be formed from a plurality of flex plates spaced from each other with spacers that provide rigidity in circumferential and radial directions and flexibility in an axial direction. The number of flex plates used may be varied to accommodate different turbine engines. The adjustable transition duct support system may have natural frequencies for circumferential and radial modes above two engine orders.

16. An adjustable transition duct support system for a transition duct that channels hot gases from a combustor exit to a gas turbine inlet of a turbine engine, comprising:
-
a transition duct body formed from an outer wall that forms an internal passage extending between an inlet and an outlet of the transition duct body; an adjustable forward transition flexible support assembly in contact with the transition duct body, wherein the forward transition flexible support assembly is formed from a base extending toward the transition duct body, and a first side support arm and a second side support arm extending from the base to the transition duct body; wherein the first side support arm is formed from a plurality of first side flex plates spaced from each other with spacers, wherein the first side flex plates provide rigidity in circumferential and radial directions and flexibility in an axial direction; wherein the second side support arm is formed from a plurality of second side flex plates spaced from each other with spacers, wherein the second side flex plates provide rigidity in circumferential and radial directions and flexibility in the axial direction; wherein the first side flex plates are formed from an outer attachment section and an inner attachment section separated by a transition section having linear sides that are nonlinear with sides forming the outer and inner attachment sections, thereby positioning the outer attachment section offset laterally from the inner attachment section; wherein the first side and second side support arms are formed from the plurality of first and second side flex plates that are aligned with each other within each arm, wherein each side support arm has their larger, outer planar surfaces aligned with a longitudinal axis of a top beam of the base; wherein first and second outer brackets of the first and second side support arms include at least one orifice with a racetrack configuration enabling axial adjustment;
wherein first and second inner brackets of the first and second side support arms include at least one orifice with a racetrack configuration further enabling the axial adjustment; and
further comprising at least one shim positioned between the first and second side support arms and the base for radial adjustment; andwherein the base is formed from a top beam and a bottom beam that are coupled together via first and second outer columns separated by a middle column and wherein the first and second columns have thicknesses less than a thickness of the middle column. - View Dependent Claims (17, 18, 19, 20)
