GAS TURBINE ENGINE COMBUSTOR AND ENGINEERING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine engine combustor 20 and an engineering method thereof that can suppress generation of NOx through efficient cooling. SOLUTION: The gas turbine engine combustor 20 comprises an inboard wall 32 and an outboard wall 34. A forward bulkhead 36 extends between the walls and cooperates with the walls in defining a combustor interior volume 30. In longitudinal section, a first area 54 of the combustor interior volume converges from fore to aft, and a second area 56 aft of the first area 54 converges from fore to aft more gradually than the first area 54.
