Abstract
A gas turbine engine with: a compressor section; a turbine section; a combustor, disposed between the compressor and turbine sections, having at least one combustor mounting assembly connecting the combustor to the engine. Each combustor mounting assembly has: a longitudinal axis; and an articulating joint having a first and second portion constrained from relative translation transverse to the longitudinal axis, and where said first and second portion have a multiple rotational degrees of freedom relative to each other about axes transverse to the longitudinal axis.
Claims17
A gas turbine engine comprising:
- a compressor section;
- a turbine section;
- a combustor, in flow communication with the compressor and turbine sections;
- at least one combustor mounting assembly adapted to support the combustor within the engine, the combustor mounting assembly having:
- a longitudinal axis;
- and an articulating joint having;
- a first portion;
- a second portion;
- and at least one longitudinal slide surface, the first and second portions having mating concave and convex curved surfaces, said curved surfaces each having a curvature in two mutually orthogonal planes, wherein the articulating joint has a translational degree of freedom parallel to said longitudinal axis and wherein said first and second portion have a plurality of rotational degrees of freedom relative to each other about axes transverse said longitudinal axis.
A combustor for a gas turbine engine, the combustor comprising:
- at least one combustor mounting assembly having:
- a longitudinal axis;
- and an articulating joint having a first and second portion, the first and second portions having mating concave and convex curved surfaces, said curved surfaces each having a curvature in two mutually orthogonal planes to provide opposing spherical joint surfaces, said first and second portion having a plurality of rotational degrees of freedom relative to each other about axes transverse said longitudinal axis, and wherein the first and second portions are mutually nested sleeves.
A combustor for a gas turbine engine, the combustor comprising:
- a pin having a longitudinal axis and a first spherical surface slidingly engaging a second mating spherical surface of a combustor boss, wherein at least one of the pin and boss includes one of:
- an internal longitudinally sliding surface;
- and an external longitudinally sliding surface.
