Lift Foils – Advanced eFoil Propeller and Shroud Design
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...
PropExpert 2021: Press Release
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...Prediction Confidence: NavCad Features to Reduce Calculation Uncertainty
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...Planing Craft in NavCad: Data, Settings, and Options
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...Rudder Design: Practical and Analytical
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...
Article: Thruster Tech – Capturing Performance Data for Design of Unmanned Vehicles
Conducting a sea trial is a necessary step upon delivery of a ship. This activity not only documents and validates anticipated ship speed and power, but if done correctly also provides performance data that can be useful for design purposes. The same holds true for...
NavCad 2021: Press Release
New features for improved Vessel-Propulsor-Drive system simulation Development in 2021 for HydroComp NavCad offers new features across the range of applications. Towed barge prediction One of the more component-intensive applications for NavCad is a towed barge being...After-market Modification of Propellers to Achieve Performance Objectives
Propeller hydrodynamics can be complicated and messy, and sometimes the combination of propeller, vessel shape, gearbox, and engine are less than perfect. Age or lack of maintenance can also compromise performance – frequently causing an overload of the engine and a...
