Abstract
A support housing for use in distributing fuel in a gas turbine engine includes a main body defining an inlet aperture, a plurality of outlet apertures, and a substantially planar mounting surface. A first fuel channel has a wall that defines a first flow space and a support member extends across the first flow space and has a long axis oriented at an oblique angle with respect to the mounting surface.

A method of manufacturing a support housing, the method comprising:
- coupling a base portion of the support housing to a positioning device;
- forming an outer wall and an inner wall on the base portion using an additive manufacturing process, the outer wall extending in a first direction, the outer wall and the inner wall spaced a first distance from one another, the first distance being at least a critical distance;
- forming a support member between the inner wall and the outer wall;
- and
- forming a cover wall using the additive manufacturing process, the cover wall extending from the outer wall to the support member to the inner wall and cooperating with the outer wall, the inner wall, and the base portion to enclose a first space.

A support housing for use in distributing fuel in a gas turbine engine, the support housing comprising:
- a base portion defining an inlet aperture and a substantially planar mounting surface;
- a boss portion extending from the base portion and defining a plurality of outlet apertures;
- a first fuel channel having a first wall that defines a first flow space;
- a second fuel channel having a second wall that defines a second flow space, the first flow space and the second flow space being annular spaces that are spaced apart from one another;
- a first plurality of support members extending across the first flow space and having a long axis oriented at an oblique angle with respect to the mounting surface;
- and
- a second plurality of support members extending across the second flow space and having a long axis oriented at an oblique angle with respect to the mounting surface.
