Propeller design is one of the most complicated compromises in naval engineering, balancing thrust, cavitation, vibration, ...

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 ...

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 ...

The propellers of the world's ships and boats create a constant drone that disrupts ocean life. New propeller designs based on loops could one day quiet that drone and be more fuel efficient. Sharrow ...

Two mechanical sails have been installed on board Jumbo's heavy lift vessel (HLV) Jumbo Jubilee. The wind assisted ship propulsion (WASP) solution is the latest in a series of innovative technologies ...

French electric marine drive specialist BlueNav is preparing to put a more natural spin in its lineup. The all-new Whale Design propeller features blades that follow the contours of a whale to improve ...

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 ...
