Abstract

Aircraft designs rely on aerodynamics to understand how air flows and the generated lift and drag forces. This study investigates the fluid aerodynamics of a 1/5 scale Cessna 182 aircraft prototype using both experimental and numerical methods. The main objective is to analyze the drag force acting on the prototype and validate the findings through a comparative approach. In the Experimental Analysis, a prototype of 1/5 Cessna 182 was 3D printed and tested in a wind tunnel. Drag force acting on the prototype was directly measured using load cell, Arduino and software. Then, drag force is measured. In the Numerical Simulation, 1/5 scale Cessna 182 was produced using SolidWorks. Mesh independency was checked. Moreover, the model was meshed and analyzed using Ansys Fluent. Drag coefficient over the prototype was calculated. Furthermore, numerical study provided velocity distribution around the prototype, offering further insights into the airflow characteristics. For Comparison and Validation, the experimentally measured drag coefficient and the numerically calculated drag coefficient were compared. Good agreement was found between the two analyses. Using experimental and numerical analyses provide valuable data for understanding the aerodynamic performance of the Cessna 182 aircraft. The successful validation of the numerical simulation demonstrates its potential for further aerodynamic investigations and design optimization.
