Method and apparatus for providing an afterburner fuel-feed arrangement

An afterburner fuel-feed arrangement comprising:

• an elongate fuel spraybar for distributing fuel to the afterburner section of a turbo-combustion engine, said spraybar having a longitudinal axis and including at least one elongate fuel pipe and an elongate, aerodynamic-shaped shroud surrounding said fuel pipe, said spraybar configured to be mounted in a casing of a turbo-combustion engine and thereby project said surrounded fuel pipe into an interior through-core of the engine in cross-wise orientation to a core gas flow thereof for establishing an installed configuration of said spraybar;
• and
• said shroud having an interior lateral sidewall including a pipe-receiving portion, said pipe-receiving portion configured to abuttingly engage a corresponding shroud-engaging portion of an exterior surface of said fuel pipe, said pipe-receiving portion configured to maintain the position of said fuel pipe when received therein relative to said shroud.

An elongate, aerodynamic-shaped shroud for an afterburner fuel-feed arrangement, said shroud being configured to surround at least one elongate fuel pipe and having an interior lateral sidewall including a pipe-receiving portion configured to abuttingly engage a corresponding shroud-engaging portion of an exterior surface of an engaged elongate fuel pipe, said pipe-receiving portion being configured to maintain the position of an engaged elongate fuel pipe relative to said shroud.

An afterburner fuel-feed arrangement comprising:

• an elongate fuel spraybar for distributing fuel to the afterburner section of a turbo-combustion engine, said spraybar having a longitudinal axis and including a plurality of elongate fuel pipes and an elongate, aerodynamic, elliptically-shaped shroud surrounding said fuel pipes, said spraybar configured to be mounted in a casing of a turbo-combustion engine and thereby project said surrounded fuel pipes into an interior through-core of the engine in cross-wise orientation to a core gas flow thereof for establishing an installed configuration of said spraybar;
• and
• a pair of said plurality of fuel pipes being arranged adjacent and substantially parallel to one another in said shroud and said pair of fuel pipes being oriented crosswise to the core gas flow.

An afterburner fuel-feed arrangement comprising:

• an elongate fuel spraybar for distributing fuel to the afterburner section of a turbo-combustion engine, said spraybar having a longitudinal axis and including a fuel-receiving spray head in fluid communication with a plurality of elongate fuel pipes surrounded by an elongate, aerodynamic-shaped shroud, said spray head configured to be mounted in a casing of a turbo-combustion engine and thereby project said surrounded fuel pipes into an interior through-core of the engine in cross-wise orientation to a core gas flow thereof for establishing an installed configuration of said spraybar;
• and
• said shroud having an interior lateral sidewall including a pipe-receiving portion, said pipe-receiving portion configured to abuttingly engage a corresponding shroud-engaging portion of an exterior surface of one of said plurality of elongate fuel pipes, said pipe-receiving portion configured to maintain the position of a fuel pipe, received therein, relative to said shroud.
