FUEL MANIFOLDS

A fuel injection system includes an outer support (102) defining a fuel manifold and an inner support (104), with a feed arm (106) extending radially between the inner support (104) and the outer support (102). A plurality of outlet openings (108) extends in an axial direction from the feed arm (106) for feeding respective injection nozzles. The feed arm (106) defines a plurality of fuel passages (134) therethrough in fluid communication with the fuel manifold and outlet openings (108) to supply fuel from the fuel manifold to the outlet openings. A heat shield (140) extends from the outer support (102) to the inner support (104) and extends about the outer support (102) and the feed arm (106) to provide heat shielding to the fuel manifold and the fuel passages.
