In an advanced Multi-rotor Unmanned Aerial Vehicle (UAV), the existing methodology of the propeller and its parametric modification leads to provide the various performance characteristics by inducing the operating efficiency. The subsisting solution for obtaining the thrust, rate of climb and forward speed by proliferating the propeller configuration and modification the design aspects in propeller by varying the pitch angle and consisting parameters in a Multi-rotor UAV. Instead of adding or modifying the design aspects, this article recommends the propeller with attaching Convergent-Divergent (C-D) Nozzle duct, which leads to producing the augmented thrust efficiency than the normal functioning system. And the comparison of the propeller with and without attaching the convergent nozzle duct, divergent nozzle duct, C-D nozzle duct has been analyzed using the numerical simulation and scrutinizing the optimized conceptual design of propeller is done with the help of ANSYS Workbench, where the design methodology is modeled by CATIA. By the result of the simulation, it leads to provide the efficient characteristics and design aspects of the Multi-rotor Unmanned Aerial Vehicle.
