Abstract: A fuel nozzle for a gas turbine engine includes a feed arm including a fuel passage for issuing a spray of fuel. A nozzle assembly is fixed at an upstream end of the feed arm having a fuel inlet in fluid communication with the fuel passage. A fiber optic cable is configured to collect burner radiation for a pyrometer input and has a first end centered within an optical connector of the nozzle assembly and a second end exposed from the spray outlet. The fiber optic cable fitted within the feed arm and nozzle assembly has a permanent bend radius preformed in the fiber optic cable. The bend radius can be equal to or greater than the minimum bend radii for the fiber optic cable to serve as a wave guide in wavelengths for monitoring combustion.

Abstract translation: 用于燃气涡轮发动机的燃料喷嘴包括具有用于发出燃料喷射的燃料通道的进料臂。 喷嘴组件固定在进料臂的上游端，具有与燃料通道流体连通的燃料入口。 光纤电缆被配置为收集用于高温计输入的燃烧器辐射，并且具有以喷嘴组件的光学连接器为中心的第一端和从喷雾出口露出的第二端。 安装在进料臂和喷嘴组件内的光纤电缆具有在光纤电缆中预成型的永久弯曲半径。 弯曲半径可以等于或大于光纤电缆用作波导管用于监测燃烧的最小弯曲半径。
