Sectorised CMC combustor for a gas turbine

The chamber assembly has a combustion chamber placed between internal and external metallic casings (15, 25). The chamber has internal and external walls and a chamber base linked to the walls to form an assembly divided into chamber sectors (100) between which a sealing joint (13) is placed. Each s...

Beschreibung
Zusammenfassung:	The chamber assembly has a combustion chamber placed between internal and external metallic casings (15, 25). The chamber has internal and external walls and a chamber base linked to the walls to form an assembly divided into chamber sectors (100) between which a sealing joint (13) is placed. Each sector has internal and external wall sectors (110, 120) and a bottom chamber wall sector (130). Elastically deformable connection pieces (17, 27) connect the casings respectively at the sectors (110, 120). A single ring (32) contacts with the sector (130), and is connected to the chamber sectors. The chamber sector is made from a single ceramic matrix composite piece. The sealing joint includes a fibrous structure made of refractory fibers, and is partially densified by a ceramic matrix.
