MULTIPOINT FUEL INJECTION SYSTEM AND RELATED MANUFACTURING METHOD

A multipoint fuel injection system comprises an injection system segment (102) including a circumferentially extending outer support (104) defining a fuel manifold with a plurality of manifold passages (106) extending circumferentially therethrough. A first connector (108) is included at a first circumferential end of the outer support and a second connector (110) is included at a second circumferential end of the outer support opposite the first circumferential end. The first and second connectors are each configured to connect each manifold passage with a manifold passages of a respective outer support of a circumferentially adjacent injection system segment. The system includes a circumferentially extending inner support (112) and a plurality of circumferentially spaced apart feed arms (114) extending radially between the inner support and the outer support. A plurality of outlet openings (116) extend in an axial direction from each feed arm for feeding respective injection nozzles.
