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.

Abstract: A fuel injector (1) having a chamber (7) with a fuel inlet (8) and a plurality of fuel outlets (10), and including a fuel distributor (18) that is arranged in the chamber (7) for the purpose of distributing fuel introduced into the chamber (7) via the fuel inlet (8) to the outlets (10). The fuel distributor (18) includes a generally rotary symmetric distributor body (19).

Abstract: 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.
