Additively Manufactured Annular Fuel Manifold

A gas turbine engine case comprising:

• a case wall having an inner surface and an outer surface;
• at least one fuel inlet;
• a circumferentially-distributed plurality of fuel injectors protruding inward from the case wall and each having an outlet;
• and
• a fuel plenum fluidically between the at least one fuel inlet and the fuel injectors and configured so that each inlet of the at least one inlet is coupled to feed multiple injectors of the plurality of fuel injectors,
• wherein,
• the fuel plenum comprises a plurality of first legs and a plurality of second legs circumferentially alternating with the plurality of first legs;
• and
• for each injector of the plurality of fuel injectors, an associated said first leg and second leg converge from opposite circumferential directions but with forward axial component.
