Architecture Examples for Electrified Propulsion Aircraft

2022-08-01
CURRENT
AIR8678
The application of electric power for aircraft propulsion can take a variety of forms, ranging from partial electric to full electric. The introduction of electric engines to drive propulsors, along with the variety of available methods to generate electricity and store energy offers great degree of new design freedom for next-generation aircraft and aircraft architectures. This newfound design freedom exposes a need within the aviation industry to establish a common design language for electrified propulsion. While this need for a common design language is recognized, the intent of this document is to encourage innovation, providing reference architectures as a launching point for future work in this area. This document will describe potential electrified propulsion architectures and provide examples.

CURRENT
ARP8676
Create and publish a list of terms relevant to electrified propulsion aircraft with summary text descriptions. The terms and descriptions will not provide full explanations, diagrams, and other detailed technical descriptions. These deeper descriptions will be addressed in other documents. This document defines the relevant terms and abbreviations related to the design, development, and use of electrified propulsion in aircraft. This definition is provided to enable a consistent use of technical language throughout the standards developed by the E-40 committee.

Safety Considerations for Electrified Propulsion Aircraft

2019-04-02
WIP
ARP8677
This SAE Aerospace Recommended Practice (ARP) discusses particularities to be considered when performing the safety assessment of electrified propulsion aircraft. Its main focuses are: • The failure modes of electrified propulsion components • Methods to evaluate failure rates of electrified propulsion components • Effects of failures on example electrified propulsion system and aircraft architectures • Particular risks, common causes, and zonal considerations specific to electrified propulsion The guidance in this document may be used to generate inputs for system and aircraft safety assessment activities.
