Abstract

Wind tunnel testing of scaled down model of flight vehicles is a must to generate aerodynamic data. Maintaining geometrical similarity between wind tunnel model and prototype is of prime importance during fabrication of such wind tunnel models. This not only requires accurate NC tool path generation for aerodynamic profile but also execution of the same through a wide variety of precise CNC machines selecting optimum cutting parameters. It was required to machine a wind tunnel model in Indonesia Low Speed Tunnel using its existing fabrication facilities. Fabrication of different components of such a wind tunnel model and complexities associated with it has been presented in this paper.
