Designing Noise Reduction Propeller System for DJI Matrice 300 Drone

Abstract

This study on designing a noise reduction propeller system for the DJI Matrice 300 drone addressed the growing concern of noise pollution, user safety, and regulatory compliance posed by unmanned aerial vehicles (UAVs). The project aimed to develop an innovative solution to mitigate the noise generated by the drone, focusing on the design of a "Toroidal" propeller. Initial assessments of noise levels from standard propeller designs were conducted to establish a baseline for comparison. The Toroidal propeller design was chosen for its potential to reduce noise emissions while maintaining the drone’s thrust, overall performance, and f light stability. Using SolidWorks, the propeller design was modelled and then 3D printed for testing. The tests demonstrated a significant reduction in noise emissions compared to standard designs. This outcome highlights the effectiveness of the Toroidal propeller in addressing noise pollution concerns associated with UAVs. The paper concludes by emphasizing the potential impact of the project’s f indings on the drone industry, particularly in terms of reducing noise pollution, improving user safety, and ensuring regulatory compliance. Future research could explore improvements to the propeller design and its application in different UAV models and environments.
