Distributed Electric Propulsion (DEP)
Multiple small electric motors for boundary layer ingestion and control.

DEP uses many smaller propulsors along the wing or fuselage to re-energize boundary layers, improve stall margins, and enable new configurations (blown lift, differential thrust for yaw). Key engineering challenges are fault tolerance, thermal management, electromagnetic interference, and integration with hybrid-electric power systems.
