INTERNAL FUEL MANIFOLD HAVING TEMPERATURE REDUCTION FEATURE

摘要

A fuel manifold assembly (22) for a gas turbine engine (10) comprises an annular fuel manifold (21) and a plurality of fuel nozzles (30) circumferent ially distributed about the fuel manifold (21). The fuel manifold (21) has a t least one fuel conveying passage in fluid flow communication with the plur ality of fuel nozzles (30) and defines at least one location susceptible to overheating between two of the plurality of fuel nozzles (30). A slot (50a, 50b, 50c) extends through the fuel manifold (21) in the susceptible location to reduce heat transfer in the fuel manifold (21) while maintaining the fue l manifold assembly (22) dynamically balanced.
