Selective step turbine nozzle

A turbine nozzle (18) includes segments (18a) of outer and inner bands (30,32) supporting corresponding vane pairs (28). The bands adjoin each other at corresponding ends (42,44) along splitlines (46), with each band having a forward land (42a, 44a), an opposite aft land (42b, 44b), and a middle lan...

Beschreibung
Zusammenfassung:	A turbine nozzle (18) includes segments (18a) of outer and inner bands (30,32) supporting corresponding vane pairs (28). The bands adjoin each other at corresponding ends (42,44) along splitlines (46), with each band having a forward land (42a, 44a), an opposite aft land (42b, 44b), and a middle land (42c, 44c) extending therebetween. The forward lands have a nominal aft-facing step (48), the aft lands have a nominal forward-facing step (50) and the middle lands are nominally flush.
