Several years ago, an aeronautical designer installed an aeronautical version of a paddlewheel into model airplane wings, to achieve the phenomena of “lift” at much lower speeds. Maritime hydrofoils ...

Factors such as rotational speed and the volume flowrate of the water stream compared to sailing speed determine propulsive efficiency of marine propellers, with peak propeller efficiency being ...

Soon, electric passenger ferries skimming above the surface across the seas may become a reality. A research team has created a unique method for further developing hydrofoils that can significantly ...
