Abstract
A casting (52) for a support housing (50), including: a fuel manifold (56) comprising an a-stage gas gallery (80) and a b-stage gas gallery (82); a-stage and a b-stage rocket bases (60) integrally cast with the fuel manifold (56), the a-stage gas gallery (80) in fluid communication with the a-stage stage rocket bases and the b-stage gas gallery (82) in fluid communication with the b-stage rocket bases; and one oil tube passageway (64) for each fuel rocket base (60), each oil tube passageway (64) spanning from an upstream end (66) of the fuel manifold (56) to an interior (68) of a respective fuel rocket base (60). Each oil tube passageway (64) is disposed radially inward of an inner perimeter (102) of the b-stage gas gallery (82).
