Design and Development of Bladeless Propulsion System for UAV Applications
Main Article Content
Abstract
In aviation, the traditional propulsion systems featuring exposed propellers pose significant safety risks and by eliminating the hazards posed by exposed propellers, this innovation seeks to provide a safer operating environment. Bladeless propulsion systems offer a more energy-efficient alternative to traditional fans and propellers. By using the Coanda effect and airfoil-like shapes, these systems induce airflow without rotating blades; to get efficient thrust generation, airflow can be optimised with help of Bernoulli’s principle. Through designing and virtual testing using tools like CATIA and Computational Fluid Dynamics (CFD), the project aims to refine the nozzle attachment to Electric Ducted Fans (EDFs) to optimise performance and ensure effective propulsion. Ultimately, this initiative marks a noteworthy stride towards enhancing the safety and efficiency of aviation propulsion systems. This combination of safety, efficiency and manoeuvrability positions bladeless propulsion as a promising technology for the future of Unmanned Aerial Vehicles (UAVs), with potential applications ranging from surveillance and reconnaissance to package delivery and beyond.
