Abstract
An integrated APU is provided having a combined starter/generator device mounted within the gearbox housing so as to reduce the number of reduction gears, bearings and other redundant components sufficiently to eliminate the need for a separate lubrication oil scavenger pump as well. Further integration and savings can be achieved by de-coupling the fuel pump and lubrication pump from the gearbox and driving those pumps instead by an electric motor.
