    • An improved mixing tube design and fuel nozzle that allows for a more uniform and thorough mixing of fuel and air being fed to the combustor of a gas turbine engine, wherein each of a plurality of mixing tubes comprises a pair of concentric hollow cylinders that define a ring-like, annular path for the flow of fuel between the two hollow cylinders in each mixing tube, a plurality of air injection slots formed in the concentric hollow cylinders defining corresponding air flow paths from the outside into the interior of each mixing tube, and one or more fuel injection ports formed in selected ones of the plurality of air injection slots that allow for the flow of fuel from the annular path formed by the hollow cylinders into the air flow path, resulting in significantly better mixing and improved thermodynamic behavior of the fuel and air mixture downstream of the nozzle and upstream of the combustor.
    • 一种改进的混合管设计和燃料喷嘴,其允许将燃料和空气进一步均匀且充分地混合到燃气涡轮发动机的燃烧器中,其中多个混合管中的每一个包括一对同心的中空圆筒, 在每个混合管中的两个中空圆柱体之间的用于燃料流动的环形环形路径,形成在同心中空圆柱体中的多个空气注入槽限定从外部到每个混合管的内部的相应空气流动路径,以及 一个或多个燃料喷射口形成在多个空气喷射槽中的选定的空气喷射槽中,允许燃料从由中空圆筒形成的环形路径流入空气流动路径,导致显着更好的混合和改进的热力学行为 燃料和空气混合物在喷嘴下游和燃烧器的上游。
