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 ...

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 ...

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 ...

It’s a rare occasion when a piece of engineering transcends its pure industrial function and becomes art. And it’s even rarer when that metamorphosis is the byproduct of a quest for better performance ...

At the very crux of engineering is the desire to problem-solve, optimize, and squeeze out every bit of efficiency possible from the system being built. Aircraft design and aeronautical engineering ...
