Fixed pitch propeller for inland vessels
Inland shipping demands high quality propellers. A propeller must convert a lot of power into thrust with high efficiency and comfort. All this on a relatively small propeller diameter. No cavitation and vibration may occur.
In order to meet these demands, we pay close attention to the speed. This is variable and low on the tops. The result is a low vibration level.
Furthermore, the blade surface, the blade shape, the profiles and the number of blades determine the result. Therefore, the propeller is designed with a so-called skew (Sabelmodel). This significantly reduces the vibration level. In addition, we choose a blade thickness with a large reserve. The material stress in the CuAlNi material is never exceeded and less propeller damage will occur.
