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 ...

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 ...

Arguably there is no more important piece of the vessel’s drive train than the propeller. If propeller geometry is out of whack, either from inaccurate design or a strike in the water, the results, if ...

High-fidelity simulations demonstrate how the number of blades affects the wakes of rim-driven thrusters.

Controllable, or Variable Pitch Propellers are just one type of propulsion used on ships. Controllable pitch propellers vary the angle of each blade to control the amount on thrust produced by the ...
