Gas Turbine Stationary Shroud Seals
US Patent:
3947145, Mar 30, 1976
Filed:
Oct 7, 1974
Appl. No.:
5/513001
Inventors:
Frank Michel - Swarthmore PA
Egidio J. Ruffini - Havertown PA
Egidio J. Ruffini - Havertown PA
Assignee:
Westinghouse Electric Corporation - Pittsburgh PA
International Classification:
F01D 902, F01D 904
US Classification:
415217
Abstract:
A seal is provided between adjacent stationary annular shroud members in a gas turbine. The shroud members have an axially directed gap disposed between their adjoining ends. Each adjoining end of each stationary shroud has a shoulder arrangement which provides support for a seal disposed across the gap. The shoulders on the ends of the shrouds provide restraint against radially inwardly directed dislocation, and a blade ring which supports the shroud members themselves, provides restraint against axial and radially outwardly directed dislocation. The seal prevents escape of hot motive fluid from the generally axially directed working fluid flow path.
Slidable Stator Seal
US Patent:
3938906, Feb 17, 1976
Filed:
Oct 7, 1974
Appl. No.:

Thomas M. Szewczuk - Claymont DE
Assignee:
Westinghouse Electric Corporation - Pittsburgh PA
International Classification:
F01D 1100
US Classification:
415139
Abstract:
A slidable seal is disposed in one end of each stationary arcuate shroud segment in a gas turbine. The seal is forced by a spring across a gap between adjacent shroud segments, to abut against an end of an adjacent shroud segment. The slidable seal helps control fluid leakage in both the axial and the radial direction.
