Abstract

A seal for use between an annular combustor and a turbine nozzle, disposed downstream of the combustor, is provided with means for effectively innerconnecting the combustor with a sidewall surrounding the nozzle. The sidewall includes an upstream extending radially projecting flange and the combustor includes an axially projecting downstream extending flange. The seal includes means for frictionally engaging each of these flanges and retaining them in a sealing relationship while permitting axial and radial frictional sliding motion therebetween. In addition, the present invention provides means for passing cooling air from a surrounding plenum through the seal in a cooling fashion to a pocket formed between the combustor-associated flange and a film-promoting lip which comprises a portion of the combustor liner.

Dependent claims

A seal for use between an annular combustor and a turbine nozzle disposed downstream of the combustor, the nozzle including a circumscribing sidewall, wherein the seal comprises:

an upstream-extending first flange associated with the nozzle;
a downstream-extending second flange associated with the combustor;
clamping means for frictionally clamping and engaging said first flange, said clamping means including first and second spaced and opposed walls, each of said walls abutting and frictionally engaging said first flange, and further including tensioning means for applying a clamping load between said first and second walls said clamping load effective to hold each of said first and second walls in said abutting and frictional engagement with said first flange;
and said clamping means having a portion projecting from one of said walls for frictionally retaining and engaging said second flange.
