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.
