Boltless turbine nozzle/stationary seal mounting

The invention comprises the use of a split retaining ring (110) cooperating with an inner nozzle support member (60) to retain nozzle segments and a stationary seal (130) without the use of threaded fasteners. Elimination of bolt heads from the rotor/stator cavity reduces windage losses and enables...

Beschreibung
Zusammenfassung:	The invention comprises the use of a split retaining ring (110) cooperating with an inner nozzle support member (60) to retain nozzle segments and a stationary seal (130) without the use of threaded fasteners. Elimination of bolt heads from the rotor/stator cavity reduces windage losses and enables a shortening of the inner nozzle band overhang, reducing the requirement for high pressure cooling and cavity purge air.
