Hydrofoils

One or more foils for supporting the hull are connected to the lower ends of the support arms. When the hydrofoil craft has accelerated to a sufficient velocity through the water, the lift created by the foils raises the hull above the water's surface, thus eliminating the hull's resistance. Attempts to create a hydrofoil had been made in England as early as 1861. The first hydrofoil to be tested successfully was built by Enrico Forlanini from Italy.

It used a ladder system of foils and a 60 hp engine driving two counter-rotating air props. A March 1906 Scientific American article by American hydrofoil pioneer William E. Baron Hanns von Schertel worked on hydrofoils prior to and during World War II in Germany. ChubsaFOIL2. Seaplane History -Goose. High flying torpedo or low flying aircraft? Ray Vellinga edited video.

This course deals with theory and design of hydrofoil sections; lifting and thickness problems for sub-cavitating sections, unsteady flow problems.

2.23 Hydrofoils and Propellers (13.04), Fall 2003

It focuses on computer-aided design of low drag, cavitation free sections. The course also covers lifting line and lifting surface theory with applications to hydrofoil craft, rudder, and control surface design. Topics include propeller lifting line and lifting surface theory; computer-aided design of wake adapted propellers, unsteady propeller thrust and torque. The course is also an introduction to subjects like flow about axially symmetric bodies and low-aspect ratio lifting surfaces, and hydrodynamic performance and design of waterjets. We will also do an analysis of performance and design of wind turbine rotors in steady and stochastic wind.

This course was originally offered in Course 13 (Department of Ocean Engineering) as 13.04. Microsoft® Excel software is recommended for viewing the .xls files found on this course site.
