Waterjets are fun. They give you great maneuvering control and promise much higher efficiency at high speeds. But that flexibility comes with the price of more subtle limits on performance. Used incorrectly, waterjets perform worse than propellers. This article focuses on the merits of waterjets, with focus on the most important factor: efficiency.
We all want to feel good about paying for engineering analysis. Sometimes the best answer drives us to maximize value, rather than minimize cost. In those cases, you do better to go beyond basic safety and search for enhancements. Today we discuss four engineering tasks where you can maximize your value. Extract every last drop of knowledge from your engineering project.
No discussion of hydrofoils is complete without addressing their application to the 2013 America’s Cup yachts. Catamarans screamed across the ocean. But with all that excitement, we sometimes forget how the crew jeopardized their lives in every race. This article presents an engineering perspective on the America’s Cup hydrofoils of 2013, with options for improvement.
Why would an airplane company design a ship? When considering hydrofoil ships, aircraft share many of the same requirements. More specifically, every hydrofoil vessel needs a method of motion control, even sailing hydrofoils. This article discusses the problem of hydrofoil control and several solutions.
If you want it done best, do it yourself! DMS developed a custom built high performance computer (HPC) for CFD calculations. But the exciting part: it cost about what you paid for that Dell workstation!
Stability and seakeeping are frequently misunderstood. To understand the limits of these sciences, we must unveil the motivation behind their development. How to guarantee ship safety on an uncertain ocean?
