SWEEP FLOW STRUCTURES FOR FUEL SYSTEMS

In accordance with at least one aspect of the present disclosure, there is provided a fuel system (100) of an aircraft engine (10), comprising: a fuel conduit interface (102) connecting a fuel conduit (104) to a component of the fuel system (100); and a sweep line structure (107, 207, 121). The sweep line structure (107, 207, 121) includes an inner surface (108) facing toward, extending around, and defining a cavity (110) around the fuel conduit interface (102), and an outer surface (112) opposite the inner surface (108), the cavity (110) being fluidly sealed relative to the outer surface (112).
