Noise mitigation of drone by modifying propeller blade

Abstract

Drone belongs to class of Unmanned Aerial Vehicle (UAV) that have good manoeuvring abilities in both hovering as well as cruising operations. Because of these capabilities, the drone industry has experienced significant growth in both militaries as well civilian purposes. Their versatility and numerous applications have driven an ever-growing demand, and several companies are in the process of transforming urban transport by lifting it to the skies. Nevertheless, this progress has created increasing concerns regarding noise pollution, mainly due to the fact that drones fly at relatively low heights and also remain in close proximity to densely populated urban areas. Therefore, in order to use drones on the same scale as conventional vehicle for transportation as well as many other civilian and military purposes, it is necessary to mitigate the noise generated by drones.
