Abstract
A composite structure and an associated exhaust washed structure are provided which may be formed of ceramic matrix composite (CMC) materials. A method of fabricating a composite structure which may include the CMC material is also provided. A composite structure may include a corrugated septum extending in a lengthwise direction. The composite structure may also include a flute within which the corrugated septum is disposed to form, for example, a partitioned flute assembly.
Claims18
A method of fabricating an exhaust washed composite structure comprising:
- providing a corrugated septum comprised of a ceramic matrix composite (CMC) material extending in a lengthwise direction;
- curing the corrugated septum;
- positioning a bulk acoustic absorber so as to be interspersed with convolutes of the corrugated septum;
- forming a flute of CMC material;
- and
- disposing the corrugated septum following curing and the bulk acoustic absorber within the flute to form a partitioned flute assembly.
A method of fabricating an exhaust washed structure comprising:
- providing a wall member;
- and
- positioning a plurality of partitioned flute assemblies upon the wall member and laterally adjacent another partitioned flute assembly so that each partitioned flute assembly extends lengthwise along the wall member, wherein each partitioned flute assembly comprises:
- a corrugated septum comprised of a ceramic matrix composite (CMC) material extending lengthwise;
- and
- a flute of CMC material having the corrugated septum disposed therein.
