Abstract
An aircraft auxiliary power system using a turbine to provide rotational power to a gearbox having coupled to it electric generators and pumps. Between the gearbox and turbine a clutch is provided. The clutch is disengaged when the turbine is started, thus reducing drag on the turbine shaft during starting, and the clutch is engaged after the turbine is started to provide rotational power to the coupled electric generators and pumps.
