SAE 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. The electrification of aircraft propulsion is an emerging area which holds much promise for revolutionizing transport aircraft and enabling new mobility options. These technologies have the potential for carbon footprint reduction, noise reduction, improved performance, new aerodynamic efficiencies, and better utilization of energy infrastructure. 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 drive systems to drive propulsors, along with the variety of available methods to generate electricity and store energy offers a great degree of new design freedom for aircraft and aircraft architectures. This newfound design freedom exposes a need within the aviation industry to establish a common design language for electrified propulsion. The purpose of this document is to establish a common language on a new domain, new technologies, and new architectures that describe electrified propulsion aircraft to reach a common interpretation.
