Original Abstract Submitted

A fuel nozzle/swirler assembly includes a venturi including a heat shield retaining wall. A backplate is connected to the venturi and includes a plurality of purge orifices extending through the backplate. A ceramic matrix composite (CMC) heat shield includes a heat shield attachment wall engaged between the heat shield retaining wall of the venturi and the backplate, and a seal member is arranged between the backplate and the CMC heat shield. The plurality of purge orifices are arranged between the seal member and the venturi and provide a flow of purge air therethrough to flow through a radial gap. The seal member provides a force against the CMC heat shield to axially engage the heat shield attachment wall of the CMC heat shield against the heat shield retaining wall of the venturi.
