WIG CRAFT

Hello guys..Today we are going to talk about Wig Craft.

  Wig means wing-in-ground.At first glance you may feel that this is not a vessel.But Convention on the International Regulations

 For the Preventing Collisions at Sea, the 1972 vessel definition is a non-displacement craft wig craft that is also a vessel.WIG craft is defined as a vessel capable of operating completely above the surface of the water on a dynamic air cushion created by aerodynamic lift due to the ground effect between the vessel and the water's surface. WIG craft are capable of operating at speeds in excess of 100 knots.A wig craft has a cruise over the surface of the sea at heights of up to 7 meters, using wings to generate lift.  They rely on the aerodynamic interaction between the wings and the surface and operate over flat areas, such as frozen lakes or plains;  like a hovercraft.

There are several names for this craft: A ground-effect vehicle (GEV), a wing-in-ground-effect (WIG), ground-effect craft, wingship, flarecraft and ekranoplan according to the Russians.

Let us now discuss the history of wig craft

By the 1920s, the ground effect phenomenon was well-known, as pilots found that their airplanes appeared to become more efficient as they neared the runway surface during landing. In 1934 the US National Advisory Committee for Aeronautics issued Technical Memorandum 771, Ground Effect on the Takeoff and Landing of Airplanes, which was a translation into English of a summary of research up to that point on the subject. The French author Maurice Le Sueur had added a suggestion based on this phenomenon: "Here the imagination of inventors is offered a vast field. The ground interference reduces the power required for level flight in large proportions, so here is a means of rapid and at the same time economic locomotion: Design an airplane which is always within the ground-interference zone. At first glance this apparatus is dangerous because the ground is uneven and the altitude called skimming permits no freedom of maneuver. But on large-sized aircraft, over water, the question may be attempted ..."

 By the 1960s, the technology started maturing, in large part due to the independent contributions of Rostislav Alexeyev in the Soviet Union[6] and German Alexander Lippisch, working in the United States. Alexeyev worked from his background as a ship designer whereas Lippisch worked as an aeronautical engineer. The influence of Alexeyev and Lippisch remains noticeable in most GEVs seen today.

A wig craft cannot carry a large number of passengers, but it can carry very fast transport.This very unique craft wig craft is in widespread use today.If you are interested in shipping, you should definitely have a general understanding of this wig craft.To fly this wig craft you need to have extensive knowledge of both aeronautics and navigation.And one of the most important things to know while driving this Vessel.These are the Convention on International Civil Aviation (ICAO Convention) and the Convention on the International Regulations

 for Preventing Collisions at Sea (COLREG).
