THERMAL AGING CHARACTERISTICS OF AERO-SPACE WIRE INSULATION.
Abstract
Life versus temperature curves of wire and cable insulations are needed to provide aircraft design engineers with information to design electrical circuits utilizing the minimum wire sizes required to maintain maximum reliability and yet reduce weight and bulk to a minimum. To establish the feasibility of obtaining such curves a procedure, employing functional evaluation and principles of statistical analysis, was developed and applied to produce curves of five wires representing the variations in insulation layer constructions specified in MIL-W-5086A. Cycling temperature studies were conducted on three of these wires, verifying the application of a relative aging factor formula which can be used to convert cyclic aging to the equivalent aging of a single temperature exposure.
