Abstract: A method for synchronizing multiple generators includes positioning a pilot feature of a shaft of a first generator positioned at a first angular position that is substantially aligned with a first predetermined reference point located at a predetermined angular position relative to an axis, locking the shaft of the first generator at the first angular position, aligning a pilot feature of a first shaft of a second generator with a second angular position that is substantially aligned with a second predetermined reference point located at a position relative to the axis that is substantially equal to the predetermined angular position, calculating an angular difference between the two angular positions, and rotating a second shaft splined with the first shaft of the second generator about the axis in another direction, based on the calculated angular difference.

Abstract: A turbine engine compressor design utilizing multiple component integration, thereby reducing the number of required engine components. In conventional compressor designs, a multiple component system makes it difficult to predict the structural behaviors due to thermal and mechanical loading during transient conditions. The compressor design of the present invention has three main parts: a forward bearing housing, a bell-mouth (heat shield) and a coupled impeller shroud/diffuser. Such a design achieves the design objectives of the present invention, including reducing weight, reducing cost, minimizing tolerance build up and improving aerodynamic performance by utilizing multiple component integration for multiple modes of engine operation.
