Abstract
A seal assembly, includes a first brush supported between first and second plates, a second brush supported on the first and second plates transverse to the first brush seal, and a third plate attached to the second brush.
Claims18
An annular seal assembly defining an axis, comprising:
- a first brush supported between first and second plates and extending radially inward with respect to the axis;
- a second brush supported on and in direct contact with radially outward facing surfaces of the first and second plates transverse to the first brush, the second brush having at least a first portion extending in a first axial direction and a second portion at least partially extending in a second axial direction opposite to the first axial direction, the first portion being angled radially outward relative to the axis defined by the seal assembly and the second portion being angled radially outward relative to the axis defined by the seal assembly;
- and
- a third plate attached to the second brush.
1 more element
A method for assembling an annular seal assembly defining an axis, the method comprising the steps of:
- joining a first plate and a second plate to define a u-shaped radial cross section with a radially inward facing opening, relative to said axis;
- inserting a first bristlepack into the radially inward facing opening;
- positioning a second bristlepack adjacent to, and in direct contact with, said u-shaped radial cross section and transverse to said first bristlepack such that a first portion of the second bristlepack extends in a first axial direction and is angled radially outward relative to the axis, and a second portion of the second bristlepack extends in a second axial direction that is opposite the first axial direction and is angled radially outward relative to the axis;
- and
- joining a third plate to said second bristlepack.
2 more elements
A turbine engine, comprising:
- a compressor section;
- a combustor in fluid communication with the compressor section;
- a turbine section in fluid communication with the combustor, an annular seal assembly within at least one of said compressor section, said combustor, and said turbine section, said annular seal assembly defining an axis and including a first brush supported between first and second plates and extending radially inward relative to the axis, and a second brush supported on, and in direct contact with, the first and second plates transverse to the first brush, the second brush having at least a first portion extending in a first axial direction and a second portion extending in a second direction opposite the first axial direction, the first portion being angled radially outward relative to the axis defined by the annular seal assembly and the second portion being angled radially outward relative to the axis defined by the annular seal assembly, and a third plate attached to the second brush.
