Combustor liner cap assembly

摘要

A liner cap assembly (30) is disclosed for use in a gas turbine engine combustor (12). The assembly includes an outer ring (52) that extends along an axis. Multiple struts (44) are circumferentially arranged about an inner diameter of the outer ring (52) and extend radially inwardly therefrom. A plate (46) is supported by and axially aligned with the struts (44). The plate (46) includes multiple circumferential openings (66) that support a collar (38) and a premix tube (42) at each of the openings (66). The plate (46) is arranged between leading and trailing edges (80,82) of the struts (44) to provide a stiffened liner cap assembly (30) that is robust and resistant to the vibrations typically found in dry low NOx systems.
