A 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.
HMCS Bras d'Or (FHE 400) was a hydrofoil that served in the Canadian Forces from 1968 to 1971. During sea trials in 1969, the vessel exceeded 63 knots (117 km/h; 72 mph), making her the fastest unarmed warship in the world at the time.
The Pegasus-class hydrofoils were a series of fast attack patrol boats employed by the United States Navy. They were in service from 1977 until 1993. They were in service from 1977 until 1993. These hydrofoils carried the designation "PHM" for "Patrol Hydrofoil, Missile."
The Sparviero-class fast attack hydrofoil was designed in Italy by the Alinavi society, a consortium of the American company Boeing, the Italian government's naval research branch, and Carlo Rodriquez , a Messina-based builder of commercial hydrofoils, based on Boeing's Tucumcari for the United States Navy.
Raketa (Russian: Раке́та, lit. 'Rocket') was the first type of hydrofoil boats commercially produced in the Soviet Union.First planned in the late 1940s as "project 340" by chief designer Rostislav Alexeyev, the vessels were manufactured from 1957 until the early 1970s.
The hydrofoils help, as do the three modes of operation. “Rather than going directly from floating to flying, we have this intermediate mode, foil. That foiling mode allows us to get through the ...
Enrico Forlanini (13 December 1848 [1] – 9 October 1930) was an Italian engineer, inventor and aeronautical pioneer, known for his works on helicopters, aeroplanes, hydrofoils and dirigibles. He was born in Milan. His older brother Carlo Forlanini was a physician. [1]
Ferries reach Ponza from Naples, Terracina, Formia and Anzio; there are also hydrofoils (aliscafo) from Anzio and Formia that take about 75 minutes. The ferries and hydrofoils may not depart to and from Ponza during severe weather conditions. Much of Ponza is accessible by car and a bus runs the length of the island.
