COMBUSTOR ASSEMBLY FOR GAS TURBINE ENGINE

摘要

A combustor liner assembly (46) includes a liner assembly (56), including a hot dome (82), a hot wall (78, 80), and an impingement shield (76, 96). The liner assembly further includes a convector assembly (58). The combustor liner assembly further includes an impingement dome assembly (60), including a ring-shaped portion (104) defining a plurality of apertures (106) configured to receive a plurality of fuel injectors, and a face (126). The ring- shaped portion and the face define an annular passage (128), and the face defines a plurality of apertures and a plurality of orifices (130). The convector assembly and the impingement dome assembly are operably coupled to one another, and the plurality of orifices of the face are configured such that the hot dome is exposed to air flowing in the annular passage of the impingement dome assembly. The combustor liner assembly is configured to provide flow communication between the annular passage of the impingement dome assembly and the plurality of fuel injectors.
