Wind tunnel project
Ever since, these early wind turbines have been put to use in an experiment comparing various types and models of wind turbines. Wind turbines of both the horizontal and vertical type have been built.
The available models are classified as follows:
|Horizontal axis wind turbines:||vertical axis wind turbines:|
|2-blade horizontal axis wind turbine||Savonius rotor|
|3-blade horizontal axis wind turbine||C rotor|
|6-blade horizontal axis wind turbine||H rotor|
Modèles verticaux :
Windkanal = wind tunnel
To test the wind turbines, a small wind tunnel with a corresponding control unit was built by pupils in the context of the Windmobile extracurricular activity. The control unit was developed as a project assignment by a Year 6 technician class as part of its “Énergie et Environnement (ENVIE)” syllabus.
The first part of the test involves determining the start-up speed of the individual wind turbines, while the second part electrically charges the wind turbines at a designated wind speed. Drawing on the results of the two test parts, the children or pupils must then determine which of the miniature wind turbines performs the best.
The findings are then compared with real wind turbines and expanded upon by the experiment leader.
The wind tunnel project has been a permanent fixture of the Windmobile@school activity since 2007.
