Self-adjusting seal structure
Abstract
Abstract A SELF-ADJUSTING SEAL STRUCTURE TO PREVENT LEAKAGE OF HIGH-PRESSURE COMPRESSOR AIR BETWEEN THE TRANSITION PORTIONS OF ANNULARLY SPACED COMBUSTION CHAMBERS TO THE FIRST STAGE OF A GAS TURBINE. THE COMBUSTION CHAMBERS ARE CYLINDRICAL IN CROSS-SECTION AND THE TRANSITION MEMBERS ARE ARCUATE IN CROSS SECTION AT THEIR OUTLETS. THE OUTLETS ARE IN CLOSELY SPACED ANNULAR RELATION AND JOINTLY DEFINE A SUBSTANTIALLY CONTINUOUS ANNULAR OUTLET FOR THE HOT COMBUSTION GASES FOR MOTIVATING THE TURBINE. THE SEALING STRUCTURES ARE DISPOSED BETWEEN EACH PAIR OF ADJACENT TRANSITION MEMBERS AND ARE PROVIDED WITH A PAIR OF VSHAPED MEMBERS, AXIALLY ALIGNED, AND OPPOSITELY SPRING BIASED INTO WEDGING SEALING RELATION WITH THE SUPPORT STRUCTURES EXTENDING FROM THE TRANSITION MEMBERS, TO THEREBY SEAL THE SPACES BETWEEN THE ADJACENT TRANSITION MEMBERS.
