Patent Images
1. A fuel nozzle apparatus, comprising:
- an annular injection ring disposed coaxially along a centerline axis and having a circumferential fuel gallery therein, and including a radial array of fuel orifices communicating with the fuel gallery;
an annular ring support disposed coaxially along the centerline axis and radially inward of the annular injection ring;
and a support arm interconnecting the annular ring support and the annular injection ring,wherein a forward portion of the support arm joins the annular ring support at a forward junction and an aft portion of the support arm extends axially aft of the forward portion to join the annular injection ring at an aft junction,wherein the forward portion extends in a radially outward direction and the aft portion extends in a radially inward direction,wherein the annular injection ring is cantilevered from the annular ring support by way of the support arm.
