ABSTRACT:
A plurality of accessories operatively associated with a gas turbine engine are driven by electric motors. A first motor controller initiates operation of a starter/generator mechanically coupled to the engine. After the engine has been started, the motor controller is used to accelerate other accessory motors at a predetermined rate after which they are each electrically coupled to the starter/generator for continued operation. Throughout this operation, the first motor controller serves as a back up for a second motor controller which is dedicated to the operation of a fuel pump motor. Other modes of operation can be achieved as well by reason of the flexibility provided by motor driven accessories.
