Agriculture drones face important challenges regarding autonomy and construction, as flying time below the 9-minute mark is norm, their manufacture requires several tests research before reaching proper flight dynamics. Therefore, correct design, analysis, of structure are imperative to address aforementioned problems ensure a robust build that withstands tough environments this application. In work, analysis implementation Nylamid motor bracket, aluminum sandwich-type skeleton, carbon fiber tube arm in 30 kg agriculture drone presented. The mechanical response these components evaluated using finite element method ANSYS Workbench, material behavior assumptions assessed universal testing machine implementations. general description models numerical results This early prediction allows for mass optimization cost reductions. fast dynamics applications set restrictions ductile materials such this, requiring extensive structural manufacture. Experimental showed maximum variation 8.7% composite 13% material. properties polyamide nylon allowed 51% reduction compared 6061 alloy optimized same load case brackets design. low complexity skeletons translated into implementation. Finally, overall performance through data gathered during test, showing adequate design process.
