SAE Recommended
Practice in the works
regarding durability of
aircraft electric engines
SAE International recently announced that its E-40
Committee on Electrified Propulsion has introduced
an important new work in progress, SAE ARP8689:
Endurance Tests for Aircraft Electric Engines.
ARP8689 will provide guidance on testing durability
and integrity requirements of electric engines.
As new technologies, architectures, and aircraft
designs emerge, the need to demonstrate safe
operation under all operational limits, as well as the
service life duration of an electric engine, becomes
critical. A Recommended Practice for a normalized
test procedure ensures that failure modes are
properly addressed and manufacturers can rely on
durable engines.
" Before electrical engines power traditional or even
radically new design aircraft, these engines will be
required to demonstrate both endurance and
durability, " said Richard Ambroise, Chair of SAE's
E-40 Committee and head of propelling at Airbus.
" The ARP8689 Recommended Practice will help the
industry achieve this requirement and that is needed
in the near future. "
Recent regulatory activity, including EASA's recently
published special condition for electric/hybrid
propulsion systems and the FAA's proposed
rulemaking, addresses endurance and durability
demonstration. The ARP8689 Recommended Practice

August 2021
will help the industry achieve
these requirements.
Since the SAE E-40
Committee's inaugural meeting
in March 2019, the group has
brought together more than 240
experts from industry, regulatory
authorities, and research, with
expertise and skills across the
spectrum. Diverse segments
include representation from
automotive, general aviation,
eVTOL, commercial aviation,
rotorcraft, and engines.
ARP8689 adds to the
committee's portfolio of
documents in work, which
include:
