The large cavitation tunnel holds 400 cubic metres of water, which are pumped towards a scale model of the propeller design being tested.
Along one wall is a row of cabinets with numbered models of propellers. The collection goes back to the 1930s and includes around 1,600 propellers with varying blade angles and shapes.
A hydraulic system makes it possible to change the angle of the propeller blades even after the propeller has been installed on the vessel.
