The main points we wanted to adress in our project were the visual and also the haptical component of our topic. We wanted the visitors to use a physical component as well as letting them see the complicated calculation as a visualization helping them understand the subject of fluid dynamics better. We also wanted to make the booth as modular as modular as possible to ensure simpilfied maintenance.
Our contact Mr. Wieddecke showed us a 1:4 scaled model of a wind tunnel and we were also able to get a also a short peek onto the 1:1 scaled windtunnel.
Mr. Wieddecke explained specific differences in the construction of windtunnels to us, like why their 1:1 windtunnel is curved and also which model of a windtunnel would be the easiest to construct regarding our project.
The frame of the wind tunnel itself is cutout on all four sides to fit the fan, the screen and the plexiglass board with the description.
The plexiglass board is cut out on the visitor facing side providing the user with a aluminium rod which has a scaled down version of a wing, a drop or a spoiler on the other end.
Each of these objects contains a gyroscope which is wired to an arduino board connected to a computer. The computer and other technical equipment is located below the windtunnel itself.
The gyroscopes and the IR-sensor are constantly sending data packages which allow us to move the digital shape via the modification of the code. For the gyroscopes, we only allowed them to send the data of one axis, a full 360° rotation is therefore not possible.
