Testing MIT's Toroidal Drone Propeller Design & Sound #shorts

Introduction

In this article, we'll delve into the creation and testing of toroidal propellers, a cutting-edge development from MIT's Lincoln Laboratory. These propellers are engineered to be significantly quieter than typical drone propellers. Let's explore how these were crafted and how they fare in an actual test.

Crafting the Toroidal Propeller

Step 1: Modeling First, the toroidal propellers were modeled using Fusion 360 software. This step allowed for precise design and customization tailored for performance and quiet operation.

Step 2: 3D Printing Next, the modeled propellers were 3D printed. This phase presented some challenges due to the propellers' thin structure, demanding fine attention to detail during the printing process.

Step 3: Annealing To enhance durability, the printed propellers underwent an annealing process. Annealing helps fortify the plastic, making it less prone to breakage under stress.

Step 4: Finishing Touches As a final step, the propellers were coated in nail polish. This coating serves as a protective layer, potentially contributing to both durability and aerodynamic performance.

Testing the Propellers

To evaluate the performance and sound characteristics of the toroidal propellers, a comparison was made against standard propellers.

Stock Test Before anything else, a baseline sound test was conducted using regular propellers to set a reference point for the new ones.

Toroidal Propeller Test The moment of truth arrived. The toroidal propellers were mounted, and their sound profiles were evaluated upon operation. The article's video demonstrates this test, highlighting the variances in noise levels and operational efficiency.

Conclusion

The toroidal propeller test showcases the advancements in drone technology presented by MIT. Stay tuned for further updates on the results and implications of this innovation.
