Project Summary and Motivation
Project Summary and Motivation
Rapid prototyping is extensively used for manufacturing sandwich structure components for drones and unmanned aerial vehicles (UAVs). To demonstrate the efficacy of small-scale sandwich structures for aerospace applications, I designed a first-person view (FPV) drone airframe in ANSYS DesignModeler by assigning the composite sandwich material construction (carbon fibers and foam).
This experiment’s goal was to design the drone airframe's intricate parts using CAD techniques in ANSYS and utilize the ANSYS FEA optimization module to assess the optimum dimensions of the 3D model for structural integrity.

3D Modeling of the Drone Airframe- Static Structural Analysis
Similar to the wing bracket experiment, I performed a numerical mass optimization using FEA tools in ANSYS DOE to obtain the minimum mass and corresponding optimum hole diameter and drone structure thickness.
Total deformation (mm)
Equivalent Stress (MPa)
By conducting a simple static load analysis on the structure, I utilized FEA tools in the built-in ANSYS' Response Surface Optimization' (DOE) to perform a complex mass optimization process.
