Standards Group SAE Issues Guidance On Durability and Integrity of Electric Propulsion
The new ARP8689 document from SAE International is intended to help electric propulsion system developers meet the requirements of regulators for durability and integrity.

SAE International, the global industry association focused on establishing engineering standards in the mobility sector, has proposed new guidance for companies developing electric propulsion systems for aircraft. The group’s E-40 Committee on Electrified Propulsion has just published its ARP8689 Endurance Tests for Aircraft Electric Engines document on the durability and integrity testing for new electric engines.

The document sets out recommended practices covering test procedures that will ensure that all failure modes are fully addressed. The SAE committee says that having a common approach across the rapidly developing electric aviation sector will fulfill the need to demonstrate the safe operation of electric engines under all operational limits and also to establish the duration of their service lives.
