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