Final Year Project: 3D Scanning and Airfoil Selection Analysis

This project report details the process of 3D scanning and airfoil selection, utilizing the Hexagon Romer Absolute Arm 7325OSI and Polyworks software for data acquisition and analysis. The report describes the scanning procedure, including parameter adjustments and data collection to generate point cloud data. It covers data processing, including cleaning, reduction, and polygon mesh creation. The project focuses on measuring cross-sections and standardizing the airfoil profile, using both Polyworks and CATIA V5 for analysis. The airfoil selection process is explained, with a focus on NACA airfoils and the use of the NACA airfoil tools generator to create a new profile. The report compares the scanned blade profile with NACA 4412 and NACA 4413 airfoils using Qblade software. The report also provides a brief overview of airfoil basics and related terms. The project concludes with an analysis of the airfoil profile, considering parameters like chord length, camber, and thickness, and comparing the final airfoil profile with NACA 4412, demonstrating the practical application of 3D scanning and reverse engineering in mechanical engineering.
