Speed \u200b\u200bhydrofoil in the Gulf of Naples        (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4L’ hydrofoil It is a particular boat that stops or at low speed is kept afloat by the hydrostatic thrust or the displacement (Archimedes principle). When it reaches a sufficient speed propelled by an engine or sailing, thanks to the lift of particular immersed surfaces (hydroal connected to the hull) it emerges totally, with a consequent important reduction in the advancement resistance. Under these conditions, this boat can reach speeds of over 50 knots (93 km\/h) with moderate energy expenditure. Hydrofoil on Lake Como The first heightver prototype was built by Enrico Forlanini in the early twentieth century. [first] For a long period he remained in an experimental phase until in the 1950s he began to operate in the internal waters of the United States. Absolutely the first open route in Italy (and in the world) was in May 1953 between Locarno (Switzerland) and Stresa (Italy) on Lake Maggiore. The hydrofoil, of the “PT10” model (gold arrow), was built by Supramar, a Swiss company that then granted the construction license to the Rodriquez shipyards in Messina.        (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4The PT10 hosted 32 passengers at the 35 knots cruise speed (about 65 km\/h). [2] The first “line” hydrofoil used for maritime connections in Italy was the arrow of the sun, built in 1956 at the Rodriquez shipyards in Messina: it was the predecessor of the ‘PT20’ model. Destined for the Messina-Reggio Calabria routes (in 15 min) and Messina-Napoli (in 4h and 1\/2), its cruise speed was 35 knots (about 65 km\/h), thanks to two 650 HP engines each . 18 meters long and 8 wide, it housed 70 passengers (some documents report 72 passengers). On March 24, 2016, the largest hydrating hydrofoil was launched in the world, with 350 passengers, the Italian hydrofoil Gianni M. [3] The last hydrofoil produced was launched in May 2019 by the Liberty Lines; His name is Carmine.        (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Voloire Aliscafo moored in the port of Como The functioning of the high school is based on the principle of obtaining the sustenance force of the vehicle through the lift generated by the immersed part of some wings connected below the hull called Hydrofoils. At low speeds, the hydrofoil behaves like a conventional ship. As the speed increases, the pressure of the water under the wings, combined with the depression that is formed above the same, generates a force of lift opposite to the weight of the vehicle. Over a certain speed this force causes the complete escape of the hull from the water. The only parts that remain immersed, in addition of course to the wings and relative “strut” connection of these with the hull, are the propeller (connected to the end of a long axis) and the possible helm of direction. When the hull is completely raised, the only resistance of advancement in the water is that produced by the wings that keep it raised, resistance lower than that which it would have produced at equal speed if it had remained immersed. The wings can be partially immersed or completely immersed. The type of wing partially immersed has an intrinsic ability to adapt to the height of the waves encountered in navigation; The completely immersed wings type requires a continuous control command of the portion of the wings in navigation to adapt to the height of the waves encountered. Hydrofoil in China The efficiency of an hydrofoil is greater the more reduced its displacement; This has made its operating principle applicable on vehicles up to about 30 m in length. In Italy, the largest fleets are found in Campania (for the connection with the islands of the Gulf of Naples) and in Sicily (for the connection with the Aeolian Islands, the Egadi and Ustica islands). All -crime are also on duty on the three major Italian lakes (Garda, of Como and Maggiore). Given its high speed and low exposure as a target to the torpedoes, it has a certain use in various military marines as a naval half of coastal patrol and as a destroyer. For the Italian Navy, the Sparviero class (1973) were launched first, then, in the years 1977-1984, 6 vehicles of the Nibbio class, very compact and speed vehicles of the order of the 41 knots, armed with a cannon of 76 mm and two anti -voucher missiles. Due to the difficult seal in a large sea (the waves cannot be higher than the distance between the bottom of the chiglia and the wings) and the changed strategic choices that took place from 1990 onwards, the Italian Navy has replaced its hydrofoils with conventional means , like patrollons and corvettes. Among these, the new minor units, such as the class Commanders , whose operational skills are expanded by the availability of an embarked helicopter.
