Designing Electric Propulsion Systems for UAVs [PDF]

open access: yes, 2011
Due to the advantages of electric motors and electric batteries, the electric propulsion systems are widely used in UAVs [1,2]. The UAV's performance and endurance, the payload capacity and the flight time of the vehicle are affected highly by the structure and design of the electric propulsion system. In this paper, a new systematic design methodology
