Abstract
An inner fixed structure (IFS) seal arrangement may comprise an IFS comprising an inner skin, and outer skin, and a cellular core located between the inner skin and the outer skin, an IFS seal, a seal retainer configured to retain the IFS seal, and a cooling flow channel disposed between the outer skin and the seal retainer.
Claims17
An inner fixed structure (IFS) seal arrangement comprising:
- an IFS comprising an inner skin, and outer skin, and a cellular core located between the inner skin and the outer skin;
- an IFS seal;
- a seal retainer configured to retain the IFS seal;
- and
- a cooling flow channel disposed between the outer skin and the seal retainer,
- wherein the inner skin, the outer skin, and the cellular core define the cooling flow channel configured to receive a flow of cooling air from a bypass flow path via an inlet aperture disposed in the outer skin,
- the IFS comprises an outlet aperture disposed in the inner skin for routing the flow of cooling air out of the cooling flow channel, and
- the outlet aperture is configured to direct the flow of cooling air towards at least one of the seal retainer or the IFS seal.

An inner fixed structure (IFS) seal arrangement comprising:
- an IFS comprising an inner skin, and outer skin, and a cellular core located between the inner skin and the outer skin;
- a seal standoff configured to be coupled to the IFS;
- a seal retainer configured to be coupled to the seal standoff;
- an IFS seal configured to be coupled to the seal retainer;
- a cooling flow channel disposed in the IFS defined by the inner skin, the outer skin, and the cellular core;
- an inlet aperture disposed in the outer skin;
- a plurality of apertures disposed in the outer skin;
- a cavity defined by the IFS and the seal standoff;
- and
- an outlet aperture at least partially defined by the seal standoff for routing the flow of cooling air out of the cavity,
- wherein the cooling flow channel is configured to receive a flow of cooling air from a bypass flow path via the inlet aperture, and
- the cavity is configured to receive the flow of air via the plurality of apertures.

A method of cooling a seal, comprising:
- routing a flow of cooling air from a bypass flow path to a cooling flow channel at least partially defined by a seal standoff;
- removing heat from an inner fixed structure (IFS);
- and
- routing the flow of cooling air from the cooling flow channel out the seal standoff via an outlet aperture at least partially defined by the seal standoff,
- wherein the IFS comprises an inner skin, and outer skin, and a cellular core located between the inner skin and the outer skin,
- and the cooling flow channel is disposed between the outer skin and a seal retainer,
- the seal retainer configured to retain the seal.
