Abstract
This work was devoted to design, build, and test a real physic platform for wind tunnel measurements with the main goal of either demonstrating phenomena or validate and verify mathematical theories in Applied Aerodynamics. To provide real-life examples that bring students, especially those in Aeronautical and Mechanical Engineering courses, closer to the phenomena seen in problems that are more related to the daily life of an engineer, this project developed a robust problem based learning (PBL) experimental aerodynamics didactic platform, with the design, construction, instrumentation, qualitative and quantitative analysis of a series of wind tunnel experiments with circular cylinder models (2D), streamlined and non- aerodynamic bodies, and 2D and 3D wing profiles. All the models were built by using additive manufacturing through 3D printing with ABS and PLA. The models have been carefully finished with surface painting and later instrumented by inserting pressure taps, mounting rods and attachment points for aerodynamic balance. A robust series of data was collected and statistically treated in terms of lift and drag coefficients as well as pressure distribution and flow visualization. All gathered data in the wind tunnel tests were compared with theoretical results and similar experimental data available in literature providing very good agreement.
