With the Wind tunnel in need of Test Objects to assist in wind tunnel testing. The size of the test object used must also match the size in the test section. To get the appropriate size of test object in cfd analysis to see vector speed on the test object and air flow around the wall test section whether there is interference or not. The test objects used are airfoils, balls and half balls. The test object will be placed in the test section measuring 40 cm x 40 cm with a speed of 15m /s. Furthermore, CFD analysis will be performed to get the best test object size. The object of research in this thesis is the design of test objects that will be used for practical purposes or basic research using wind tunnels. In the process of preparing this thesis, there are stages or methods of data collection that the author performs in compiling this final task, namely The Method of Literature Study, Data Analysis Method and Internet Browsing Judging from the results of vector speed analysis, the cfd simulation results are obtained using airfoil sizes 10 cm, 15 cm, 20 cm and on the size of balls and half balls using sizes 10 cm and 15cm.} }
