Abstract: A fuel distribution system for a gas turbine powerplant. A fuel injector with a cylindrical body defines a single internal plenum sealed at an engagement end, having multiple axial openings in a midsection, and injection ports in an injection end. A fuel manifold defines a hollow annular fuel chamber with substantially parallel and opposing top and bottom surfaces. One chamber wall includes multiple cylindrical channels extending between the top and bottom surfaces. Each channel is connected through the wall to the fuel chamber. Each channel has securing features to engage corresponding securing features of the fuel injectors. When a fuel injector is inserted through the top surface into one of the channels in the manifold and the securing features engage, the engaging feature protrudes from the top surface, the injection ports protrude from the bottom surface, and the axial openings are in fluid communication with the fuel chamber.
