Minimal Surfaces as an Innovative Solution for the Design of an Additive Manufactured Solar-Powered Unmanned Aerial Vehicle (UAV)

This paper aims to describe the methodology used in design and manufacture of a fixed-wing aircraft manufactured using additive techniques together with implementation technology based on solar panels. The main objective is increasing autonomy range UAV’s autonomous missions. Moreover, one targets improve capabilities aeronautical industry towards sustainable aircrafts acquire better mechanical properties owing use technologies new printing materials. Further, lower environmental impact could be achieved through renewable energies. Material extrusion (MEX) may able for stronger lighter parts by gyroids as filling printed material. proposes minimal surfaces reinforcement UAV wings. type surface was never because it not possible conventional techniques. rapid growth led many expectations methodologies industry. In this study, tests were carried out specimens different geometries address demonstrator. addition, carry prototype, 3D printer movable bench similar belt, that allows without limitations Z axis, tested. technique can structurally improved, avoid manufacturing multiple prints small will have glued later, decreasing UAV. conceptual aircraft, SolarÍO, technologies, presented. A study most innovative printers allowed an infinite Z-axis and, filler (gyroids) applied, which considerably increased parts. Finally, stated article, potential process sector future when materials more efficient processes are already developed demonstrated.
