ROTARY MACHINE AND NOZZLE ASSEMBLY THEREFOR

摘要

A rotary machine is provided. The rotary machine includes a turbine section with a casing and a ring coupled within the casing. The ring has a groove. The rotary machine also includes a nozzle coupled to the ring. The nozzle has a first end, a second end, and an airfoil extending between the first end and the second end along a longitudinal axis. The first end includes a first hook and a second hook. The first hook has a first radially outer surface, and the second hook has a second radially outer surface. The ring and the first end of the nozzle cooperate to form an anti-rotation feature that extends from at least one of the radially outer surfaces along the axis and between the hooks.
