Abstract
A method of manufacturing a hydrostatic advanced low leakage seal configured to be disposed between relatively rotatable components is provided. The method includes manufacturing a plurality of separate, independent components of the seal. The method also includes assembling the plurality of separate, independent components to form the seal.
Claims20
A method of manufacturing a hydrostatic advanced low leakage seal configured to be disposed between relatively rotatable components, the method comprising:
- manufacturing a plurality of separate, independent components of the seal, wherein the plurality of separate, independent components include a first portion and a second portion, the first portion comprising a shoe and a first beam, the second portion comprising a second beam and a base portion, the first portion and the second portion operatively coupled to each other;
- and
- assembling the plurality of separate, independent components to form the seal.
A method of manufacturing a hydrostatic advanced low leakage seal configured to be disposed between relatively rotatable components, the method comprising:
- manufacturing a plurality of separate, independent components, at least one of the plurality of separate, independent components formed from a machining process, and at least one other of the plurality of separate, independent components formed from an additive manufacturing process, wherein the plurality of separate, independent components include a first portion and a second portion, the first portion comprising a shoe and a first beam, the second portion comprising a second beam and a base portion, the first portion and the second portion operatively coupled to each other;
- and
- assembling the plurality of separate, independent components to form the seal.
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 being relatively rotatable components;
- and
- a first hydrostatic advanced low leakage seal disposed between the first component and the second component, the seal comprising:
- a base operatively coupled to one of the first component and the second component;
- a shoe extending circumferentially;
- a first beam operatively coupling the shoe to the base;
- and
- a second beam operatively coupling the shoe to the base, wherein the first beam and the second beam are independently manufactured components operatively coupled to each other with at least one of brazing, adhesive bonding, diffusion bonding, welding, and the like.
