Abstract
The present work aims to investigate and optimize the design of a self-propelled Unmanned Arm Vehicle namely UAV by using Ansys Fluent for its analysis. Design of the chosen UAV was based on HAVOC RC which is commercially available online. It has a high-wing configuration with zero dihedral angle, propelled by a single thruster powered by a Brushless DC Electric Motor and controlled wirelessly by Radio Transmitter and Receiver. The multipurpose Airplane was modeled by using Creo Parametric (Pro-E) and later on analyzed for its performance on Ansys Fluent. The modifications in the design of critical parts like wing tips, fuselage were done and later on analysis has done in order to improve its aerodynamic efficiency. It was found that the efficiency for cruise flight is better in the optimized version than in the original design. With a fewer modifications over a design the aerodynamic performance of an aircraft can be significantly improved
