    Abstract: PROBLEM TO BE SOLVED: To reduce exhausting of an NOx, a UHC and smoke by incorporating a first row passing a combustor liner at an intermediate portion of the liner, a second row coincident with the first row rear in a circumferential direction and a third row rear from the first row in a row of a dilution hole, and incorporating a specific size and a circumferential array in the hole of the third row. SOLUTION: In order to supply a jet of dilute air in a combustion area 50, a first row 52 of a dilute hole passes a liner at a substantially intermediately axially common position of an effective axial length L of the liner. A second row 54 of the hole passes the liner at a rear common axial position from the row 52 at a predetermined distance. A third row 56 of the hole passes the liner a rear common axial position at the specific distance. The specific length is longer than a predetermined distance. An arrangement with the size and circumferential direction of the hole 56 of the third row is selected to simulate to a profile specified in a flow of combustion gas generated from a rear end of the combustion can 18.

    Abstract: A low emissions combustor can 18 for an aircraft gas turbine engine includes a louvered combustor liner 24 with three arrays 52 of dilution holes 52, 54, 56. The first hole array comprises twelve equally sized, equiangularly distributed holes that penetrates the liner about midway along its axial length. The second hole array 54 comprises twelve equally sized holes, smaller than the holes of the first array, that penetrate the liner a predetermined distance aft of the first hole array 52. The holes of the second array 54 are equiangularly distributed and each second hole is circumferentially aligned with a first hole. A third hole array 56 penetrates the liner a predefined distance aft of the first array. The third holes are nonuniformly sized and nonequiangularly distributed to regulate the spatial temperature profile of combustion gases exiting the combustor can. The quantity, size, distribution and location of the holes mitigates undesirable exhaust emissions without affecting the performance or durability of the engine. Accordingly, the combustor can may be used to replace an existing combustor can in an older generation gas turbine engine.

    Abstract: An annular combustor includes an annular outer shell that includes a first flange that defines an inner diameter IDOS and an annular inner shell that includes a second flange that defines an outer diameter ODIS. An annular hood includes a radially outer hood flange and a radially inner hood flange. A bulkhead includes a radially outer bulkhead flange that defines an outer diameter ODB and a radially inner bulkhead flange that defines an inner diameter IDB. The first flange is secured at a radially outer joint between the radially outer hood flange and the radially outer bulkhead flange. The second flange is secured at a radially inner joint between the radially inner hood flange and the radially inner bulkhead flange. The IDOS and the ODB define a ratio R1 of IDOS/ODB that is 0.998622-1.001129, and the IDB and the ODIS define a ratio R2 of IDB/ODIS that is 0.998812-1.001388.
