Design of Bladeless Thruster for UAV Application

Conventional multi-copters rely on multiple propellers to achieve lift, propulsion, and altitude control. However, a new type of thruster has been developed that offers significant safety advantages by eliminating external blades. This advanced thruster features a vertical inlet duct equipped with an Electric Ducted Fan (EDF), which is paired with a specially designed nozzle ring. The unique design of the nozzle ring, which has an airfoil-like cross-section, creates a pressure differential that, combined with the Coanda effect, generates thrust without the need for externally rotating blades or propellers. This bladeless technology not only enhances safety but also offers a quieter and potentially more efficient alternative to traditional propeller-based systems
