摘要： A fuel manifold assembly for a gas turbine engine comprises an annular fuel manifold and a plurality of fuel nozzles circumferentially distributed about the fuel manifold. The fuel manifold has at least one fuel conveying passage in fluid flow communication with the plurality of fuel nozzles and defines at least one location susceptible to overheating between two of the plurality of fuel nozzles. A slot extends through the fuel manifold in the susceptible location to reduce heat transfer in the fuel manifold while maintaining the fuel manifold assembly dynamically balanced.
摘要翻译： 用于燃气涡轮发动机的燃料歧管组件包括环形燃料歧管和围绕燃料歧管周向分布的多个燃料喷嘴。 燃料歧管具有与多个燃料喷嘴流体连通的至少一个燃料输送通道，并且限定在多个燃料喷嘴中的两个之间容易过热的至少一个位置。 狭槽在易受影响的位置延伸穿过燃料歧管，以减少燃料歧管中的热传递，同时保持燃料歧管组件的动态平衡。
