This document discusses distributed propulsion technology and its potential application for future all-electric commercial aircraft. It outlines challenges with current aircraft propulsion systems, including high fuel consumption and noise and emissions. Distributed propulsion aims to address these issues by dividing thrust across multiple smaller engines distributed around the aircraft. The document reviews literature on early aircraft with distributed propulsion designs. It also examines challenges for implementing distributed electric propulsion on commercial aircraft, such as managing increased weight and electrical systems complexity.
