Paragraph starter
The integration of distributed electric propulsion (DEP) offers significant potential for enhancing aircraft performance. As reviewed by Kim, Perry, and Ansell (2018), DEP systems, which utilize multiple electrically driven propulsors, can be strategically placed to leverage aero-propulsive coupling, improve boundary-layer ingestion, and enhance control authority. This allows for novel aircraft configurations that can achieve greater efficiency and maneuverability compared to traditional designs.
