This bachelor thesis involves making electrotechnical, mechanical, improvements on a wind tunnel owned by the University of Southeast Norway (USN). These improvements involve a rebuild from a simple demonstration object to a wind tunnel eligible for academic use. The wind tunnel will be used to test the aerodynamics of geometric shapes, e.g., models of cars, buildings, planes, and more. This implies that you control and monitor parameters. The most important parameters will be wind speed (ideally 3-dimensional field measured in the entire tunnel at any given time) and density of the gas, which primarily will be affected by the air pressure, humidity, and temperature). The USN envision using the wind tunnel to perform laboratory experiments in the field of fluid mechanics for mechanical engineering students.
The wind tunnel project was initiated by the University of South-Eastern Norway (USN) in 2020 and made available as a bachelor thesis. The project was then conducted by a bachelor group at USN campus Kongsberg in the spring of 2020, and the project is referred to as the Wind Tunnel Project 2020 (WTP2020). This year's project, the Wind Tunnel Project 2021 (WTP2021), must therefore evaluate and take all work conducted by the WTP2020 into account when making decisions throughout the project period.

2. Project- and Risk management and choosing Scrum as framework.
3. Assigning roles and responsibilities to all members of the Scrum team.
