A method for installing an inner fixed structure (IFS) seal may comprise disposing a ceramic matrix composite (CMC) member over an inner skin of an IFS, disposing a seal retainer over the CMC member, and coupling the IFS seal to the seal retainer. The CMC member may be configured to thermally insulate the seal retainer from the IFS.

A rotating machine includes a rotating body configured to rotate around a central axis, and a casing configured to accommodate at least a part of the rotating body, and the casing, includes a main section made of a metallic material, and a high-porosity section made of the same material as the main section and having a porosity higher than the main section.

A thermal paid having a high temperature side located nearest a source of heat and a low temperature side. The thermal panel includes a corrugated composite material core having hot side ridges and cold side ridges. A hot side skin is attached to the hot side ridges to form a plurality of first cells. A cold side skin is attached to the cold side ridges to form a plurality of second cells. The first cells and second cells are substantially filled with an insulating material that has a thermal conductivity which is lower than the thermal conductivity of the composite material.
