Abstract: A computer apparatus and method to determine aircraft fuel mileage performance. The computer apparatus including a memory and a processor disposed in communication with the memory and configured to issue a plurality of instructions stored in the memory. The instructions issue signals to receive real-time aircraft data during aircraft flight and process the real-time data to determine real-time aircraft mass data. A calculation is performed to determine the real-time fuel mileage performance for the aircraft based upon determined real-time aircraft mass data.

Abstract: A bushing for a bearing assembly is provided. The bushing includes a tubular sleeve having an inner surface and an outer surface. An inner circumferential channel is provided on the inner surface of the bushing. An outer channel is provided diagonally on the outer surface of the bushing and is configured to be in fluid communication with a lubricant supply path. Further, the bushing includes a port connecting the inner channel and the outer channel of the bushing.

Abstract: Systems and methods for detecting ice particle accumulation is disclosed herein. In one exemplary implementation, a method for detecting ice is described in which a parameter within an interior volume of a heated conduit is measured. The method also includes detecting the presence of an accumulation of ice particles based on the parameter measured within the interior volume of the heated conduit.

Abstract: A friction stir welding spindle includes a support having a center bore. A spindle shaft is adapted to support a stir welding tool and extends within the bore. A bearing assembly allows simultaneous rotational and axial displacement of spindle shaft in the bore relative to the support. A sensing device is adapted to provide an output signal indicative of at least one of a force coincident with axial displacement of the spindle shaft and an axial position of the spindle shaft.
