Bookmark or Share- Hydrofoil - WikipediaA hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds.
- 2.972 How a Hydrofoil Works - MIT1. At low speeds the hull (body of ship) sits in the water and the hydrofoils are totally submerged in the water. 2. As the boat’s speed increases, the hydrofoils create lift. 3. At a certain speed, the lift produced by the hydrofoils equals the sum of of the boat and cargo weights. Therefore the hull comes out of the water.
- How Hydrofoils Work: Physics and LimitationsHydrofoils are underwater wings that allow boats to glide above the surface of the water, reducing drag and increasing efficiency. They work based on fluid dynamics principles, generating lift as water flows over the curved surface of the foil.
- Hydrofoil | Sailing, Boating, Design | BritannicaHydrofoil, underwater fin with a flat or curved winglike surface that is designed to lift a moving boat or ship by means of the reaction upon its surface from the water through which it moves. Ships that use hydrofoils, or foils, are themselves called hydrofoils. Hydrofoils can lift a boat’s hull.
- Hydrofoil Basics - Massachusetts Institute of TechnologyA hydrofoil is a wing that 'flies' in water. Hydrofoil is also used to refer to the boat to which the water wings are attached. A hydrofoil boat has two modes of operation: (1) as a normal boat with a hull that displaces water and (2) with the hull completely out of the water and only the foils submerged.
