(SAE International: Warrendale, PA) -- SAE has convened a new standards committee, AE-9, to write performance, reliability and testing standards for materials used in electrical/electronic systems for more-electric aircraft (MEA) and more-electric engine (MEE) applications, taking into account both pressurized and nonpressurized areas of the air vehicle.

The need for this committee arose from a panel debate held during the 2017 SAE Aerospace Standards Summit between leading materials experts from major airframe and engine manufacturers, along with research institutions.

Initially, AE-9, chaired by Al Lambourne of Rolls-Royce Plc., will concentrate on the need for advanced materials suited to electrical transmission and enhanced rationalized testing criteria.

The first three topics identified and confirmed for electrical materials standardization are:
• Permanent magnet corrosion
• Soft magnetic aging
• Capacitor materials and behavior

This new generation of SAE aerospace materials specifications focused on electrical systems design and supporting performance specifications will be dedicated to controlling or meeting the demand placed on high-performance electrical systems.
