One of the most important component of the wind tunnel is drive. The drive inside tube requires a stable and rigid clamping. There are also significant sound effects which occur during operation. For maximizing air mass is necessary to ensure a good seal. At our school we do not have possibilities for banding endless sheet metal in tube. Plastic tube which used by the municipal and meteoric water installations can provide us with some of the required physical quantities. This piece of equipment purchasing has helped us company Kostak Krsko.
This plastic piece of equipment is extremely rigid and strong. The sales's dimension is 300 mm. In the middle of the cross-section of the pipe is 12 mm high and 4.5 mm thick, the edge of which enables stable clamping of the flat flanges of the drive part of the wind tunnel. More about the installation can be seen at the link DRIVE.
