AFT RING FOR GAS TURBINE COMBUSTOR AND AFT ASSEMBLY HAVING THE SAME

摘要

PURPOSE: An AFT ring for a gas turbine combustor and an AFT assembly including the same are provided to reduce crack on an inner ring caused by the concentration of thermal stress by employing a partition having a trapezoidal cross section. CONSTITUTION: An AFT ring(30) for a gas turbine combustor comprises a partition(32) which forms a cooling path to let cooling air flow around the exterior of the AFT ring. The partition has a trapezoidal cross section and is formed in parallel with the axial direction of the AFT ring.
