Capstone Project

Overview

This project set out to solve a challenging problem: creating a drone capable of filming an IndyCar at full speed, providing smooth 4K footage from a dynamic, third-person perspective for an entire lap. IndyCars can reach speeds of up to 400 kph, and current drone technology lacks the combination of speed, maneuverability, and endurance to keep up.

What We Did

• Component Selection: We began by researching state-of-the-art drones and components, focusing on motors, batteries, and electronic speed controllers (ESCs) capable of handling extreme performance requirements. We opted for lightweight, high-power components, including TBS Lucid 12S ESCs and TMOTOR V3115 KV900 brushless motors, ensuring the drone could reach the required speeds while maintaining stability and efficiency​​.

• Aerodynamics and Design: Using CAD software, we designed an elliptical shell for the drone, reducing drag compared to traditional circular designs. We validated this choice through wind tunnel tests and Computational Fluid Dynamics (CFD) simulations in SolidWorks. The CFD analysis modeled the aerodynamic performance of the drone at speeds of up to 400 kph, confirming a drag coefficient of 0.19 and effective airflow through NACA ducts to cool internal components​

• Prototyping: The drone's shell was 3D-printed using Onyx material for its superior strength and finish. The internal frame securely housed all electronic components, with custom latches designed for easy assembly and maintenance. We conducted multiple iterations to ensure every aspect of the design met the stringent performance requirements​​.

Flight Tests

• Hover Test: Our initial tests focused on basic functionality and low-speed endurance. The drone hovered successfully for over two minutes, demonstrating stable control and effective cooling.

• Speed Tests: We conducted two major speed tests:

  1. In the first test, the drone reached 230 kph at 50% throttle.

  2. In the second test, it hit 302 kph at 80% throttle before experiencing a catastrophic ESC failure. This emphasized the need for further refinement in component testing​.

Looking Ahead The current prototype serves as a solid foundation, but improvements such as enhanced ESC testing, more robust cooling mechanisms, and potential redesigns around alternative components will be necessary. Additionally, conversations with McLaren’s IndyCar team remain open, and future iterations of the drone could have real-world applications in motorsports filming​.

This project showcased our ability to tackle ambitious engineering challenges, combining advanced aerodynamics, cutting-edge electronics, and rigorous testing to push the boundaries of drone technology.
