Electric Ducted Fan Propulsion for Small-Scale eVTOL Systems

A conceptual study of distributed electric propulsion architectures for compact vertical takeoff systems. This working paper establishes a framework for comparing efficiency, noise, and control trade-offs.

Abstract

This exploratory paper studies how distributed electric ducted fans may be evaluated as a coherent system rather than as isolated components.

Research direction

The current work defines a simulation-ready vocabulary for propulsion, control, and structural constraints. Results are intentionally presented as a research baseline, not as a validated flight claim.

Next questions

Future iterations will examine thermal behavior, acoustic signatures, and control stability under changing load conditions.
