The number of blades on a ship's propeller isn't arbitrary — it's a carefully balanced compromise between power, efficiency, ...

Subscribe to our newsletter for the latest sci-tech news updates. SINTEF has now designed and manufactured new measuring equipment for model testing of contra-rotating propellers. This could be good ...

Bronze has been the preferred material for open water and low ice class ship propellers for decades, said Finnish engineering company Aker Arctic that operates an ice model test basin in Helsinki."Few ...

The Kiel University of Applied Sciences (HAW Kiel) has started a research project dedicated to a problem that research has been grappling with for almost 20 years: the low-frequency underwater sound ...

The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher ...

Could the secret to transforming propeller design lie in the dimples of a golf ball? It might sound far-fetched, but the same aerodynamic principles that allow a golf ball to soar farther and faster ...
