Conceptual design of a dual battery power supply system for a fixed-wing VTOL UAV
In this paper, a dual battery power supply system is conceptually presented. It is based on the switching of the power supply from two batteries that power the systems on board a UAV with VTOL capabilities. So, the propulsion systems and batteries are determined using mathematical formulas and eCalc software. Therefore, the overall electrical diagram of the on-board electrical network is presented and the sections of the conductors on board the aircraft are calculated. Also, this paper presents the design stages of a dual battery system, the methods of determining the energy consumers on board the UAV, as well as the comparative performance between the proposed system and a classic system with a single battery. These performances are presented through relevant graphs that compare flight time, flight distance and the efficiency of the propulsion system in both configurations.
