Abstract:
An aircraft turbine engine Fuel Metering Unit (FMU) is provided including a main gear pump having a main drive gear and a main driven gear and a servo gear pump having a servo drive gear and a servo driven gear. The main drive gear and the servo drive gear are received on an input shaft. The main driven gear is mounted to a first shaft oriented parallel to and adjacent a first side of the input shaft. The main driven gear is in meshing engagement with the main drive gear. The servo drive gear is mounted to a second shaft arranged parallel to and adjacent a second, opposite side of the input shaft. The servo driven gear is in meshing engagement with the servo drive gear.
