We all acknowledge the environmental impact of Underwater Radiated Noise (URN) from ships, and the challenges it poses for shipping companies and shoreside organizations. While noise is produced by drive systems and other mechanical components, noise specifically from...
HydroComp’s role in the creation of this micro-sized AUV Water makes up approximately 71% of the earth’s surface, but there’s still a wide range of questions about it that need to be answered. From environmental and water quality assessments to...
New electric drive motor feature for Propulsion simulation Development for HydroComp NavCad 2021 offers new features across the range of applications. One specific highlight is NavCad’s new DC motor feature. New DC electric motor Drive option A major update for NavCad...
New features for improved wake-adapted propeller design and analysis Development in 2021 for HydroComp PropElements offers new features across the range of applications. PropElements + FINE/Marine coupling User testing is underway for the new coupling of HydroComp...
A conversation with Pete Fagan of New Hampshire eFoil Surf’s up – even with no wind or waves. Thanks to Lift Foils’ portable and versatile invention, the eFoil, the next generation of surfers is emerging. To make his dream a reality, founder Nick Leason turned to the...
Lift Foils of Puerto Rico is considered the inventor of the “eFoil” propeller-driven hydrofoil board – an electric-powered futuristic personal watercraft (The Wall Street Journal, “Surfers Want to Transform Your Commute with Hydrofoils”). The board...
New Windows “visual styles” option and other technical updates Development in 2021 for HydroComp PropExpert offers new user experience and technical features. Enhanced GUI components During 2021 HydroComp has undertaken a significant in-house initiative to enhance...
As we analyze or design a vessel, we use NavCad for hydrodynamic and propulsion system simulation. The Vessel-Propulsor-Drive system model is built upon predictions for the various component pieces of the system – resistance, propeller performance, hull-propulsor...
We all know about planing hull drag prediction and typical hull form parameters – such as deadrise, LCG, chine beam. But what about the longitudinal and transverse variation in deadrise? Or how catamaran forms affect planing predictions? What is the influence of...
We all know that rudders are a vital piece of our vessel’s operational equipment. But what determines the best type of rudder to use? How do we ensure that the rudder and propeller function well together? Can we use analytical tools to optimize a design? This...
