Abstract
A sectorized nozzle for a turbomachine, the nozzle being made up of cylindrical sectors and comprising two annular platforms interconnected by substantially radial vanes, together with an annular rail for supporting elements of abradable material, each inner platform having longitudinally-extending edges that are V-shaped, and each rail sector having, on at least one of its sides, means for bearing axially on corresponding means provided on an adjacent nozzle sector.
Claims13
A sectorized nozzle for a turbomachine, the nozzle being made up of cylindrical sectors placed end to end and each having two coaxial annular platform sectors interconnected by substantially radial vanes, and a sector of an annular rail for supporting elements of abradable material, the rail sector being radially inside the inner platform sector and being connected to said inner surface of the platform sector, each nozzle sector including on the longitudinally-extending edges of the inner platform sector, means for mutual circumferential engagement that co-operates with corresponding means provided on an adjacent sector of the nozzle, wherein the longitudinally-extending edges of the inner platform sectors form V-shapes.
