DESIGN AND IMPLEMENTATION OF A MODULAR LATTICE STRUCTURE OF THE BASIC FRAME OF AN UNMANNED AERIAL VEHICLE

Abstract

This article deals with a structure design of a modular unmanned aerial device (UAD), which allows building of various unmanned aerial vehicles (UAV), differing in number of rotors, bearing capacity, manouverability etc. This can be done using the same construction parts. Structure design consists of two basic parts (base and arm), to which additional construction parts are tied. These secondary parts can sipmly be modified as needed for building of specific configuration. Structure design has been created and analysed in the enviroment of 3D CAD system CREO. Basic structural analysis has also been executed by CREO CAE module SIMULATE. Theoretically (by a calculations in CAE module SIMULATE) a weight and bearing capacity has been verified for all of its configurations. When defining analysis, different materials has been taken into account for functional specimen (ABS plastic) and for final UAV (titanium). As a production method (3D printing) demonstrator, a 1:2 scaled model has been manufactured.
