Abstract
A combustor wall louver for ducting a flow of compressed air through an inlet opening in the combustor wall from a source of compressed air outside the combustor where the louver is a circumferentially extending member, mounted to an interior surface of the combustor wall and covering the inlet opening with outlet openings fed by a channel in flow communication between each outlet opening and the inlet opening. Preferably, the circumferential member is made of arcuate segments of cast metal removably mounted to the interior surface of the combustor wall with threaded studs.
Claims16
A combustor wall louver, for ducting a flow of compressed air through at least one inlet opening in a combustor wall from a source of compressed air outside the combustor wall, the louver comprising:
- a circumferentially extending member having circumferentially extending side walls, mounted to an interior surface of the combustor wall forming an enclosed space and at least partially covering the at least one inlet opening, the member having:
- a plurality of outlet openings in flow communication with an inlet opening, the outlet openings oriented relative to the combustor wall to generate a toroidial flow of gases within the combustor.
A combustor comprising a wall, having:
- an inlet opening in communication with a source of compressed air outside the combustor;
- a louver comprising a circumferentially extending member, mounted to an interior surface of the combustor wall and covering the inlet opening, the member having:
- a plurality of outlet openings;
- and a channel in flow communication between each outlet opening and the inlet opening, the circumferentially extending member having combustor wall abutting edges bounding the channel;
- and
- an air curtain gap defined between the interior surface of the combustor wall and the combustor wall abutting edges of the louver.
A gas turbine engine comprising:
- a compressor portion;
- a turbine portion;
- and
- a combustor portion, the combustor portion including at least one combustor wall and a louver member, the louver member having circumferentially extending side walls mounted to the combustor wall forming an enclosed space and extending circumferentially around an interior surface of the combustor wall, the combustor wall having at least one air flow opening therein,
- wherein the louver member is mounted to the interior surface of the combustor wall so that at least one louver outlet opening communicates with the air flow opening in the combustor wall, the outlet opening oriented relative to the combustor wall to generate a toroidial flow of gases within the combustor.
