Abstract
A hydrostatic seal configured to be disposed between relatively rotatable components is provided. The seal includes a seal housing. The seal also includes a shoe having a first axially extending segment, a second axially extending segment, and a radially extending segment joining the first and second axially extending segments, the shoe cantilevered to the seal housing.
Claims20
A hydrostatic seal configured to be disposed between relatively rotatable components, the seal comprising:
- a seal housing;
- and a shoe having a first axially extending segment, a second axially extending segment, and a radially extending segment joining the first and second axially extending segments, the shoe cantilevered to the seal housing, wherein the first axially extending segment, the second axially extending segment, and the radially extending segment are formed as a single unitary structure and the first axially extending segment is radially fixed to the seal housing.
A seal assembly disposed in a gas turbine engine, the seal assembly comprising:
- a first component;
- a second component, the first component and the second component relatively rotatable components;
- and
- a first hydrostatic seal disposed between the first component and the second component, the seal comprising:
- a seal housing;
- and
- a C-shaped shoe having a first axially extending segment, a second axially extending segment, and a radially extending segment joining the first and second axially extending segments, wherein the first axially extending segment, the second axially extending segment, and the radially extending segment are formed as a single unitary structure and the shoe is cantilevered to the seal housing and wherein the first axially extending segment is radially fixed to the seal housing.
A gas turbine engine comprising:
- a compressor section;
- a combustor section;
- a turbine section;
- and
- a seal assembly disposed in the gas turbine engine, the seal assembly comprising a stator, a rotor, and a first hydrostatic seal disposed between a stator and the rotor, the seal comprising:
- a seal housing;
- and
- a C-shaped shoe having a first axially extending segment, a second axially extending segment, and a radially extending segment joining the first and second axially extending segments, wherein the first axially extending segment, the second axially extending segment, and the radially extending segment are formed as a single unitary structure and the shoe is cantilevered to the seal housing and wherein and the first axially extending segment is radially fixed to the seal housing.
