Abstract

Wind tunnel (wind tunnel) is a tool to help the process of analyzing the influence of air flow around solid objects. The test section is one part of the wind tunnel that serves to place the test object. airfoil, ball and half ball. The test object in the form of an airfoil is manufactured using three methods, namely: 3D printing, laser cutting, and manual. Where, in each method using different materials. The 3D printing method uses pla material, the laser cutting method uses balsa wood material, the manual method uses polyfoam material. Then an analysis was carried out on the airfoil specimen using the Simple Additive Weighting (SAW) method, the results of the analysis obtained the final ranking with a value of 0.89 obtained from the Hot Wire manufacturing method. In addition, the airfoil test object was tested to see the difference between the lab test lift results and the lift results on the ansys software, it can be seen that the highest lift is a small airfoil measuring 10cm with the laser cutting method with a comparison percentage of 0.9848.
