This article presents an in-depth analysis of all electric-aircraft (AEA) architectures. This work aims to provide a global vision of the current AEA state of the art, to estimate the main technological gaps and drivers, and to identify the most promising architecture configuration for future electrical aircraft in the context of a twin-propeller 20-MW aircraft. The comparison between architectures is done based on three different figures of merit: reliability, efficiency, and specific power density. The methodology presented and the trade studies are applied to a narrowbody aircraft of 20 MW, equivalent to an Airbus A320, and following current efforts of government agencies to achieve cleaner air mobility within the next two decades.

电动飞机能源动力系统的未来：架构回顾

本文对所有电动飞机 (AEA) 架构进行了深入分析。这项工作旨在提供当前 AEA 最先进技术的全球视野，估计主要技术差距和驱动因素，并在双螺旋桨 20 兆瓦飞机的背景下确定未来电动飞机最有前途的架构配置. 架构之间的比较基于三个不同的品质因数：可靠性、效率和特定功率密度。所介绍的方法和贸易研究适用于 20 MW 窄体飞机，相当于一架空客 A320，并遵循政府机构当前为在未来 20 年内实现更清洁的空气流动所做的努力。
