Abstract
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.
