APU fuel system and method
DRIVE
January 2, 2013
A control for providing fuel to an auxiliary power unit ("APU") (15) includes a constant speed electrical motor (200), a first pump (25) driven by the motor (200) and a second pump (45) driven by the motor (200). The electric motor (200), the first pump (25) and the second pump (45) provide fuel at sufficient pressure/flow capacity to run the APU (15).
