CONICAL-FLAT HEAT SHIELD FOR GAS TURBINE ENGINE COMBUSTOR DOME |
摘要 |
A gas turbine engine combustor conical-flat heat shield includes an annular conical section extending upstream from and being integral with a flat section with a flat downstream facing surface which may be generally perpendicular to or canted with respect to a centerline. The flat section includes radially outer and inner edges at least one of which is circular and circumscribed about a centerline and circumferentially spaced apart clockwise and counter-clockwise radial edges having an origin on the centerline. A gas turbine engine combustor includes conical-flat heat shields in one or more circular rows arranged in a non-symmetrical or asymmetrical pattern. Two or more groups (A, B, C) of the conical-flat heat shields in the circular rows may be mounted on a domeplate and one or more of the conical-flat heat shields is different in one or more of the groups (A, B, C). |

1. A conical-flat heat shield for a gas turbine engine combustor, the conical-flat heat shield comprising:
an annular conical section extending upstream or forward from and being integral with a substantially annular flat section of the conical-flat heat shield, the flat section including radially outer and inner edges, at least one of the outer and inner edges being circular and circumscribed about a centerline, and the flat section including circumferentially spaced apart clockwise and counter-clockwise radial edges having an origin on the centerline. |
