Clocked combustor can array
The present application provides a clocked combustor can array for coherence reduction in a gas turbine engine. The clocked combustor can array may include a number of combustor cans positioned in a circumferential array. A first set of the combustor cans may have a first orientation and a second set of the combustor cans may have a second orientation.
1. A clocked combustor can array for coherence reduction in a gas turbine engine, comprising:
a plurality of combustor cans positioned in a single circumferential array, each of the plurality of combustor cans comprising a non-circular head end of equal size;
a first set of the plurality of combustor cans comprising a first orientation with a long side facing a center point of the single circumferential array; and
a second set of the plurality of combustor cans comprising a second orientation with a short side facing the center point of the single circumferential array.
2. The clocked combustor can array of claim 1 , wherein the non-circular head end comprises an oval head end or an elliptical head end.
3. The clocked combustor can array of claim 1 , wherein the first orientation comprises a clocked position of ninety degrees from the second orientation.
4. The clocked combustor can array of claim 1 , further comprising a plurality of fuel nozzles with clockwise vanes thereon.
5. The clocked combustor can array of claim 1 , further comprising a plurality of fuel nozzles with counter-clockwise vanes thereon.
6. The clocked combustor can array of claim 1 , further comprising a plurality of fuel nozzles with clockwise vanes and counter-clock wise vanes thereon.
7. The clocked combustor can array of claim 1 , wherein each of the plurality of combustor cans comprise one piece combustor cans.
8. A gas turbine engine comprising a clocked combustor can array for coherence reduction, the clocked combustor can array comprising:
a plurality of combustor cans positioned in a single circumferential array;
each of the plurality of combustor cans comprising a non-circular head end of equal size;
a first set of the plurality of combustor cans comprising a first orientation with a long side facing a center point of the single circumferential array; and
a second set of the plurality of combustor cans comprising a second orientation with a short side facing the center point of the single circumferential array.
