摘要： An afterburner fuel-feed arrangement including an elongate fuel spraybar for distributing fuel to the afterburner section of a turbo-combustion engine. The spraybar includes a fuel-receiving spray head in fluid communication with a plurality of elongate fuel pipes, which are surrounded by an elongate, aerodynamic-shaped shroud. The surrounded fuel pipes project into an interior through-core of the engine. The shroud has an interior lateral sidewall that includes a pipe-receiving portion configured to abuttingly engage a corresponding shroud-engaging portion of an exterior surface of one of the fuel pipes. The pipe-receiving portion is configured to substantially radially fix a fuel pipe received therein relative to the shroud, thus supporting and bracing the pipe and raising the eigenfrequencies of the assembly into ranges higher than those of the incorporating engine.

摘要： Method and apparatus for providing an afterburner fuel-feed arrangement including an elongate fuel spraybar for distributing fuel to the afterburner section of a turbo-combustion engine. The spraybar has a longitudinal axis and includes a fuel-receiving spray head in fluid communication with a plurality of elongate fuel pipes surrounded by an elongate, aerodynamic-shaped shroud. The spray head is configured to be mounted in a casing of a turbo-combustion engine which projects the surrounded fuel pipes into an interior through-core of the engine in cross-wise orientation to a core gas flow thereof. The shroud has an interior lateral sidewall that includes a pipe-receiving portion configured to abuttingly engage a corresponding shroud-engaging portion of an exterior surface of one of the fuel pipes. The pipe-receiving portion is configured to substantially radially fix a fuel pipe, received therein, relative to the shroud. In this manner, the fuel pipes are supported along their length, and when the pipes are abuttingly engaged with the shroud, the braced configuration is stiffened which raises the eigenfrequencies of the assembly into ranges higher than those of the incorporating engine.
摘要翻译：一种用于提供加力燃料供给装置的方法和装置，包括用于将燃料分配到涡轮燃烧发动机的后燃器部分的细长燃料喷雾杆。喷杆具有纵向轴线并且包括燃料接收喷头，其与由细长的空气动力学形状的护罩围绕的多个细长燃料管流体连通。喷头被构造成安装在涡轮增压发动机的壳体中，涡轮增压发动机的壳体将其周围的燃料管以交叉方向突出到发动机的内部通孔中，使之与核心气体流相反。护罩具有内侧横向侧壁，其包括被配置成与一个燃料管道的外表面的对应的护罩接合部分邻接地接合的管接收部分。管接收部分构造成基本上径向地固定容纳在其中的燃料管相对于护罩。以这种方式，燃料管沿其长度被支撑，并且当管与护罩邻接地接合时，支撑构型变硬，这使得组件的本征频率高于并入发动机的本征频率。
