Ship propellers are a constant compromise between efficiency, vibration, cavitation, and power delivery. This video explains why adding blades can solve serious mechanical problems, and why engineers ...

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 ...

Naval Group manufactured a new-generation propeller via a metal 3D printing process, mounted on a tripartite minehunter.This propeller is 2.5-m in diameter, supported by five 200-kg blades. The ...

A new propeller created by the Ningbo Institute of Materials Technology and Engineering (NIMTE) coated with a skin mimicking that of a dolphin holds the promise of significantly reducing fuel ...

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 ...
