Abstract

The manufacture of airfoil sections for experimental purposes for a specific profile is very expensive and time consuming. Due to the complexity of its contour and the need to have a good surface finish of the final model, airfoil model for wing tunnel test need to be manufactured precisely. This project is on manufacturing of NACA 4412 airfoil wing section for wind tunnel test. By using Computer Aided Manufacturing (CAD) and Computer Aided Manufacturing (CAM) procedure, a series of coordinates according to the NACA 4412 profile will need to be input to the machine. This method is fast and also accurate thus, allowing the time and manufacturing cost to be substantially reduced, at the same time improving the accuracy and quality of the model. The fabricated model was installed in the test section of low speed wind tunnel and connected to the 3 weight balance instruments. Series of test have been conducted and the characteristics of the airfoil based on the drag, lift and pitching moment coefficients are presented.
