Improved Ducted Fan Design for Small Flexible Wing Unmanned Air Vehicle

Digital Object Identifier 10.32754/JMT.2018.1.06 33 Abstract—Nowadays, equipment transportation or real time surveillance flights can be done with different types of UAVs (Unmanned Aerial Vehicles) ranging from quads to fixed wing vehicles and flexible winged ones. The purpose of this article is to build upon the research available in the field of small unmanned paramotor flexible winged gliders. Such a functional aerial vehicle has been built and initial flight data evaluation undertaken. In this paper we improve upon the initial design of the UAV and the flight behavior of its initial fan configuration. A new ducted structure is proposed and tested (numerically and experimental) for the electric fan propulsion system.
