About Hovercraft.

Hovercraft. 

As an archipelago , Indonesia is certainly in need of transportation facilities in sufficient quantity . Especially considering that Indonesia is a country that has a number of islands in the world . To connect the islands with other islands required sea transportation is reliable. But until recently the attention of people towards this is still lacking . Reportedly , about more than 50 % of maritime shipping sector still untapped . One sea transportation ( water ) that has a pretty good prospect and could be a multi-use function is Hovercraft . Hovercraft including the type of amphibious vehicle , in a sense can function well in aquatic and terrestrial . Hovercraft can still be used even in areas where the mud bogs or land vehicles or boats can not be used in muddy swamps .

At the time of hovercraft drove in surface or ground water , or other parts of the body hovercraft did not touch the surface of the track . At the time of driving , the vehicle drifted to a certain height according to type hovercraft are used . But it does not fly like an airplane . This makes friction with the track surface ( water or land ) can be removed so that the speed of a hovercraft can be driven up to suit the safest speed limits . Hovercraft generally used as a water vehicle that can be called a ship that does not require a dock , because after crossing the waters of the Hovercraft can go up as far as possible on the mainland on a flat surface .
And since when Hovercraft made ​​man ? Based on the literature , a philosopher and theologian Emanuel Swedenborg named Sweden in 1716 designed a vehicle which ever way it works is similar to the principles used in the Hovercraft . According to the plan of the vehicle is running with the help of humans . But since human labor is not powerful enough to run mechanized uses , the vehicle was not realized its manufacture .

One and a half centuries later, in the mid-1870s , a designer from the United Kingdom , John Isaac Thornycroft , has also made ​​a model vehicles equipped with air cushion on the bottom which aims to reduce the friction force between the vehicle body with the track surface . And in 1877 the designer from the UK has been granted a patent for the working principles of the air bearing his name. But so far, the vehicle the way he wanted it not also be realized making .
Since then, efforts to develop vehicles using air cushion is still continuing . In 1931 in Finland , Toivo J. Kaario started to design ships using air bags . He has made the construction and test yourself on its design and obtain a patent from the government of Finland . But unfortunately this effort was disrupted because of lack of funds .
The person who first used the name to refer Hovercraft vehicles using air cushion principle this is Christopher Cockerell . In 1952 the British inventor of successfully designing a vehicle based on the working principles of the Hovercraft. Its discovery is considered as the findings of the most successful than similar efforts that have been made ​​by some of his predecessors in this field. Subsequently in 1959 he succeeded in realizing this design and since that was the name used to refer Hovercraft air cushion vehicles this . And in the years following the basics of the working principle of this vehicle is used by the company to manufacture a lot Saunders Roe Hovercraft .
But at that time Hovercraft still not wearing a dress or skirt as widely used by today's Hovercraft . This section ( skirt / skirt ) was first introduced by a member of the British Royal Navy , Latimer - Needham . This section is used to support the new system called Flexible Hovercraft Skirt Systems . Skirt made ​​from a strong rubber material and mounted on the side of the entire hull ( body ) so fleeting -like Hovercraft skirt .
How does the Hovercraft to mention having more advantages than conventional ships ? Actually how the Hovercraft more like an airplane though still classed as a water vehicle . Because at the time of driving , the bottom of the vessel ( hull ) is not in contact with water . Under such conditions , the frictional forces between the hull ( the hull ) with almost no water at all . Perhaps in saying a hovercraft in a state of drift on the current . When hovering altitude ranges from a height of 15 centimeters up to 2.7 meters from the track surface . Of course depending on the type of hovercraft . The state of drift ( lifting force ) is generated from some fans ( fan ) mounted on the bottom of the vessel . Gusts of wind generated by the fans detained by skirts or skirts that are fitted around the circular hull . While forward movement on the Hovercraft produced by some of the propeller ( propeller ) aircraft like yours mounted on the top of the ship .
By way of such work , a hovercraft could travel at the speed of 130 Km per hour where conventional boats can not afford to do it . And because it can be floated on the conditions at the time of running , Hovercraft can be ridden in the water or on land .
At the moment the most widely Hovercraft operated by the British state . This is reasonable because the plant 's largest hovercraft, British Hovercraft Corporation, located in this state . England many operate hovercraft for ferry crossings .
But until today , when seen percentage , more use of the military services of this vehicle compared to the civilian world .
What about the development of Hovercraft in the homeland ?
In the early 1980s , hovercraft had been introduced by Henk Kawulusan . But unfortunately this does not get a good reception from the technologist in Indonesia.
People prefer Jet Foil technology that is considered to be more sophisticated to operate in Indonesia . Upon entering the 21st century , the Hovercraft started to be produced in Indonesia .

Is the development of Hovercraft just end there ? Hovercraft was already introduced more advanced variant again . Hovercraft that is equipped with a wing on the right and left . So the way it works is completely similar to the aircraft . Lift force occurs on the hull is not generated from blowing fan mounted on the bottom of the vessel . But more because the aerodynamic forces generated due to the speed . This force is generated by the wing mounted on the right side and left the ship . Hovercraft This type of work using the principle known as WIGE , stands for Wing in Ground Effect . And the popularity of the name was winged ship . The water vessel actually flew above the water surface . One is that it was introduced by a technician from New Zealand , Rudy Heeman . Vehicle he designed it looks like on the picture .
