What is Ground Effect?

WIG, Wing-In-Ground effect. A WIG craft is generally speaking a boat that cruises just above the water surface.

Only for members.

The telltales make the trimming of the sails and the steering of the boat easier.

Båten Stormfågeln. 

"Tanken med vår propulsion är att bara använda trycksidan på bladet

och få kraften i färdriktningen." Och "att åka med liten våt yta på tre åkytor

och då får du automatiskt litet motstånd och små vågor."

Källa: Jan Ericsson.

The boat Fulmar.

"The purpose of our propulsion is to use only the pressure side on the blade

and get the force to the direction of travel." And "to travel with a small wet area

on three travel surfaces and then you will automatically get reduced drag and small waves."

Wrong Lift explanation explained by "Circulation flow 'creating' the Velocity Field".

http://www.av8n.com/how/

http://www.av8n.com/how/htm/airfoils.html

Varför har det blivit fel?

Man skulle kunna säga att Laplace skapar Lyftkraften, eftersom hastighetsfältet beräknas

med hjälp av Laplace. Sedan korrigeras detta med superpositionerad hastighetscirculation.

Resultatet i hastighet kan räknas om med hjälp av Bernoulli till indikerat lokalt tryck,

men detta är ju ingen lyftkraftsförklaring!

Why has it got wrong?

You could say that Laplace creates the aerodynamic lift, since the velocity field is calculated

by means of Laplace. Then is this corrected with superpositioned speed circulation.

The result in velocity can be recalculated by means of Bernoulli to indicated local pressure,

but this is not an explanation of aerodynamic lift!
