About 20 years ago one of the long-time aerodynamicists was retiring and cleaning out his files.. this one was interesting..
Something Lockheed did between the F-104 and ???
about the middle-late '50s..
Somewhat resembles the "Caspian Sea Monster"..
It was tested in a reservoir just north of San Fernando..

It's a fun plane to fly on Microsoft Flight Simulator 2002! Definately an interesting idea, just not too sure on its practability.

I saw this on the Discovery channel once...

The russians have experimented a lot with theese things, they are called "WIG"...

They are pretty neat when transporting things over long distances, they make about 500 km per hour and they draw as much fuel as a larger boat...

So these machines are a "budjet" alternative for air transportation...

I bought Graham Taylor's excellent WhizzyWig plans but have not had the time to build one yet.

Airventure,
Where did you get that model for MSFS 2002? I've been looking around a few sites, but can't seem to find it.

I belive it's function is also known as ground effect or ground effect vehicles. I think basicly it means that a wing has more lift when it's closer to the ground. Airplanes exhibit this function. There a lot of rc models of these .

No, the wing has less drag rather than more lift.

The problem with flying in ground effect is that the centre of pressure is further rearward than out of ground effect. When you climb out of ground effect the nose tends to rise and the aircraft can do a back flip (as seen on hydroplanes). In fact the large 300 foot Russian Ekranoplan was lost this way.

The trick of ekranoplan design is choosing a combination of wing/tail aerofoils, sizes and locations to give automatic stability. The idea behind the Russian design is that the tailplane is out of ground effect.

There's an American company that has a couple of really sleek small craft out. Do a web search on Flightship.

WIG


The acronym WIG is from 'Wing In Ground-effect'

There is a number of companies in both the US (Flarecraft?) and in Germany who manufacture these things. There's some excellent film which demonstrates the Flarecraft machine in use. The pilot (driver?) talks aboutwhat happens if, at speed, one tip or the other hits the water. Apparently all it does at 80knots or so is jump back out, with no change to direction or stability.

The website I mentioned in my earlier post has pictures of all publicly known WIG vehicles. Channel 4 tv in the UK did a program and issued a booklet on them. The pic is of a German design (covered on the top with ripstop nylon?)

Hey Steve,

I'm not too sure where I found it, but I'll keep my eye open for it. If I come upon I'll give you a PM of where you can find it, or I can send you a .zip of it if you like.

I was wrong; the contact information on the Flightship page is in Australia. Guess we Yankees can't claim all of the good stuff, eh? http://www.flightship.net/products/
