The increasing use of drones in sectors like security, photography, and agriculture highlights the need for systems that can analyze key flight parameters—such as stabilization time, response time, and orientation—without significantly affecting drone movement. This project introduces a system for controlled-resistance testing under laboratory conditions, in which a drone travels along an arm with two degrees of freedom—yaw and pitch. A propeller at one end applies counteracting force, while a custom mount at the other enables free movement in three degrees of freedom with low-friction motion along the arm. Encoders measure angular displacements around different axes, providing accurate real-time motion data, enabling in-depth analysis of drone behavior and performance, while supporting development and refinement of external control systems.

This study focuses on enhancing thermal management in EV battery packs using an Octadecane-based ‘phase-change material’ (PCM) embedded with copper nanoparticles. While PCMs provide excellent latent heat storage, their low thermal conductivity limits heat dissipation. Copper nanoparticles were synthesized using a one-step method and dispersed directly into the PCM. The nano-enhanced material was characterized using ‘differential scanning calorimetry’ (DSC), Cryo-SEM, and thermal conductivity testing. To boost thermal performance, a polymer matrix coated with copper was developed, serving both as the battery pack’s structural frame and as a metal foam enhancer of heat transfer. A thermal system was designed around battery cells to evaluate real-world performance. This project integrates materials engineering and thermal design to achieve an effective, passive cooling solution for electric vehicles.
