Vessel hull form drag is the principal system load that ultimately determines engine power, fuel consumption, and emissions, and we know that reducing this hydrodynamic “cost” is an important design objective. But is there a “best” hydrodynamic shape to achieve least... Read more
While the primary objective of most sailing vessel designs is performance under sail, auxiliary propulsion is also an important consideration. Often, the heaviest non-structural components on a sailing vessel are the engine and its fuel. Since weight reduction is key... Read more
Tugs, trawlers, and other workboats require the ability to generate thrust for more than their own transit. They need supplemental thrust – known as “towpull” – to pull nets or push other boats. More than just “bollard pull”, towpull requires a properly functioning... Read more
Tunnel thrusters are an invaluable asset for maneuvering and docking. But how do they really function? Did you know that inlet and discharge geometry can be as important as the thruster propeller itself for a successful installation? What about thruster noise? This... Read more
We start May with a webinar focused on the interaction between propeller hydrodynamics and shafting calculations. Many naval architects and propulsion equipment professionals know the basics of shafting vibration and alignment calculations, but what about the way... Read more
In this webinar, PropCad Senior Design Engineer, Adam Kaplan, will demonstrate the new CAD file import feature in PropCad Premium 2018. This new utility helps propeller designers and manufactures extract, understand, and visualize the design data from a 3D CAD file.... Read more
