German researchers are launching a new project to tackle one of the ocean’s loudest problems. Ship propellers create massive noise that disrupts marine life. This interference breaks the communication ...

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 ...

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

A quick look at some of the largest ship propellers ever built, highlighting their massive size, engineering complexity, and ...
