Abstract
A blade outer air seal support includes, at least one arc body having a first portion and a second portion, a blade outer air seal mounting region defined at least partially between the first portion and the second portion, and an interface feature interfacing the first portion and the second portion. The interface feature is configured such that axially aligned forces are communicated between the first and second portions through the interface feature, bypassing the blade outer air seal mounting region.
Claims19
A blade outer air seal support comprising:
- at least one arc body including a first portion and a second portion;
- a blade outer air seal mounting region defined at least partially between the first portion and the second portion, and configured such that a blade outer air seal received in the mounting region contacts the first portion via a dynamic seal and directly contacts the second portion;
- and
- an interface feature interfacing the first portion and the second portion, the interface feature being configured such that axially aligned forces are communicated between the first and second portions through the interface feature, bypassing the blade outer air seal mounting region.
A method for protecting a blade outer air seal comprising:
- mounting a blade outer air seal within a mounting region of a blade outer air seal support such that the blade outer air seal contacts a first portion of the blade outer air seal support via a dynamic seal and directly contacts a second portion of the blade outer air seal support;
- and
- passing axial forces contacting the blade outer air seal support through an interface feature of the blade outer air seal support, thereby bypassing said blade outer air seal.
A blade outer air seal assembly comprising:
- a plurality of blade outer air seal arc segments, each of said arc segments being connected to two adjacent arc segments via a featherseal;
- each of said arc segments comprising a first portion connected to a second portion via an interface feature, the first portion and the second portion defining a radially inward mounting region;
- a blade outer air seal received in the mounting region and contacting the first portion via a dynamic seal and directly contacting the second portion;
- and
- the arc segments being configured such that axially aligned forces are passed through said interface feature, bypassing said mounting region.
