Abstract: A fuel control system for an aircraft includes first and second electric motor controlled fuel pumps connect in parallel with one another to a fuel line. A plurality of fuel nozzles are connected to the fuel line to issue pressurized fuel from the fuel line with the ability to throttle flow based on system needs along with the electric pumping. At least one fuel nozzle in the plurality of fuel nozzles includes a respective sensor system. A fuel controller is operatively connected to receive input from the respective sensor system of the at least one fuel nozzle, and operatively connected to control the first and second electric motor controlled pumps based on input from the respective sensor system of the at least one fuel nozzle.

Abstract: A seal assembly for preventing the flow of fluid includes a rotating component having a first sealing surface, a stationary component coaxial with the rotating component and having a second sealing surface with the second sealing surface configured to form a seal with the first sealing surface of the rotating component, and indents in one of the first sealing surface and the second sealing surface. The indents are configured to control a width of a gap between the first sealing surface and the second sealing surface to allow fluid to flow into the gap. At least two of the indents are at least partially aligned in the radial direction.
