Abstract:

Reliability is of paramount importance in aircraft electrical systems. With higher system voltages the problems of corona, arc-over, and adaptation of utilization equipment become increasingly difficult, especially in high-altitude applications. It is shown that if the criterion of maximum utilization of copper or other conductor in the transmission system is used to establish the optimum system voltage, the weight of wiring in the transmission system is reduced to within 5 to 10 of the theoretical minimum with only a moderate increase 50 in present system voltages. A simple method was evolved to determine the variation of system wiring weight and other system parameters with increase in system voltage. The method is applicable to any system, dc or ac, and to any aircraft. Application of the method to the dc and ac transmission systems on the WF-2 aircraft indicates that a weight reduction of 30 in system wiring will result with an increase of approximately 50 in systems voltage. On application of the analysis to several representative naval aircraft, best system voltage levels for future aircraft can be determined.
