WIG - Wing in Ground Effect

[masluxx]

pretty cool

[LanRous]

waves??? and i mean big waves

[thehellorhys]

this clip was like trying to sell me one "the hover wing comes in many sizes"

[endtyrany]

I like to know how they preform over waves, though they claim stable flight , I would like to know how it would react to a 8 to 12 foot rogue waves or would it cause turbulence over rough seas? From the videos i've seen they seem to be flying only on the calmest of conditions. The way i see it if they were to fly over a big enough swells could it cause them to lose stabality and possible control? Though I believe the concept is great would this invention be better off over solid ground?

[SpitfireFang]

Alot of ppl here are missing a key point. Air creates alot of drag. Two types: Parasite drag (basically drag from having air moved because of air frame pushing through air) and Induced drag (created by lift). Induced drag increases with reduced speed, while parasite increases with increased airspeed. The ground effect takes place about half of a wingspan above the ground and reduces the INDUCED drag to a very small value. As AS inc, there is no point in flying low, because Pdrag will take over..

[blite13]

Now picture a 757 flying a few feet of the ground, going at approx 500 mph and blowing through 3 rings of the Pentagon? And it was done by a guy who could hardly fly a Cessna....it's what I thought of as I watched this vid....the world wants a REAL investigation.

[vaibhav402]

@blite13 WTF!! didnt u hear...it is only for travelling above water...since boats are efficient than airplanes...but they are damn slow...this can be used instead of boats for wayyyy fast transportation..

[vaibhav402]

@blite13 i think its a great invention...instead of wasting fuel on drag created by water in ships...i'd much rather prefer wasting minimum fuel in minimum drag of a very less viscous fluid - air

[eddieyahooable]

These vehicles are f*cking insane! I pretend I am one when I fly my helicopter real low on the ground.

[jamesmcashan]

jet seaplane 1948. not new. 1920s too. US Government public owned project. water aircraft are restricted for safety. & to force the general public to go through airports. controlling crime should include reducing other peoples ability to block our resources and to endanger us. we all deserve the security of safe transport for evacuation and regular service, which government and industry do not provide. industry stops new designs to cripple us. -james mcashan for US Congress.

Why is always this kind of aircraft showed on quiet water?.

[topspeed10]

13 hp sounds pretty low. Maybe it needs 13 to stay airborne 30 hp to take off ?

[moreleftpedal]

Nothing new, dudes. Russians were doing this in the 70's and 80's with the Ekranoplan which could lift 500 tons and was over 300ft long. Speeds where very high. Do hope something gets into production though, this idea has been poo-pooed for years and is brilliant.

[brainwave420]

Why didn't I think of that ?

[utterbullspit]

@jannej312 is he saying hovel or hobel?

[part2themovie]

wow russians are like white japanese

[Rokkiteer]

It's just a shame, they are so expensive compared to a regular speedboat. I'd like to see a wig model built for the people and not just those who can afford one.

I actually live in the Baltic Sea, on the island Bornholm, so it's not hard for me to see the advantages of a Wig craft.

[taxona100]

thats what iran did



[56Edify]

Seems like it would not work in bad weather. And how fast can it turn?

[Sterlingjob]

What happens when the sea is rough!?

[madnessofmike1984]

@Sterlingjob WiGE aircraft can get over them as the air pressure pushes them even higher - they don't so much fly but it takes them over the waves

[madnessofmike1984]

@Sterlingjob it can go higher over bad seas but it won't fly like a plane, I'd love to go up in one

[Weedwacker7692]

did he say 13 HP for airfish-1???

is it manned or RC?

[BudMantheyBand]

@Weedwacker7692 HELL YEAH !!! 13hp IS THAT A LIE !!!!?????

[we5leyz]

what happens if a giant wave crashes over the craft?

[Leopoldo888]

@we5leyz The same thing that could happen to a regular boat. the advantage is that this hoovering vehicles can "jump" if needed.

[YiannisThiakos]

PLEASE>>>>>

We need help.

IF a CEO can hear me. They can connect all Aegean Sea this way and till this day noone has done it.

There is no law yet to help its creation in Greece but it would be a perfecet interconnecting among 2000 islands. Ships belong to the past...

[flightboat]

@YiannisThiakos

Nobody in Greece from companies will listening you about WIG crafts. They are listening company engineers that they are very negative in this technology with very ridiqulous exuses because they don't know antything from this technology. So CEOs are victims of their stupid associates. The same did in the past with catamarans but one CEO didn't listen them.

[Constructor88]

Future, but I still like ships better than these hybrids.

[SinisterWalrus]

@Constructor88 because, you know, I'm such a huge fan of noise pollution and current disturbance in the ocean.

[msretxe]

WHAT? WHAT IS NAME OF THIS CRAFT? WIG?NO, THIS IS EKRANOPLANE! DESIGNED BY SOVIETS IN 80s...

[bigrobnz]

the aussie navy could use these to patrol up north at a fraction of the cost of ships

[gphumze4]

I flew the FS8 while the factory was being built in Cairns, Australia. It took off and landed at 50 knots, flew beautifully, straight as a gun barrel in cruise, had state of the art radar, and if the sponson on the wing tip hit the water (during turns) it just bounced off the surface, no dramas. I would fly one of these anywhere in the world, and one day they will be everywhere. The size of the craft dictates the sea state it can fly over. The larger the craft, the higher it flies over the sea.

[bestamerica]

WOG is right,,,

wing on ground,,,

not in,,,

WIG is wrong

[velhoo76]

What actually bothers me with this is the fact they used the baltics as an example, they didnt take into account that the sea is frozen, and due to ships trtailing the sea, there are mini icebergs (iceplates sticking up) that can be quite high, which would cause problems..

[Weps17]

Well, apart from what velhoo76 says, I can't imagine these things to work smooth enough on rough seas.

[conspiracy777]

The only thing that bothers me about these is the question of what if a wing dips into the water? It seems like running at those speeds that close to the water could be trouble IF the wing were to tuck in. Then of course there is always the question of bird strikes that close to the water where most of them are. Otherwise it would be a great idea. It seems that having a small landing gear or skid for landing on a sand beach or other flat area would help to aid in options for boarding ect

[childsca]

If the wing did hit the water I think the tip would just skim the surface and not dig in. Plus with running that close to the water the air is very smooth so the should be no reason why the wing should hit the water, unless the water itself is rough. Bird strikes are a legitimate concern though. Having landing gear would add a lot of drag to the craft, especially considering that it could just beach itself like a current boat does.

[frackcha]

2:38.... look closely on the left hand side of the video..

[deepstig]

whats there?

[frackcha]

@deepstig a wingtip touching the surface

[namorsero]

Sovjet was first whit this typ of aircraft.

nice video

[b1gbanger]

Iran has built this

[putrosm]

oh really??

do you know what the company is??

[b1gbanger]

Took me some time to find the video,it's built by the iranian military industry:

/watch?v=VbiygasRFUU&feature=r­elated

from 2:00 to 2:40

[flightboat]

@b1gbanger

Iran WIG craft was a bad copy of German Airfish-3. Iran craft has stability problems as shown in the videos.

[khaos813]

look i have two personal sized craft like this, dont listen to these dumbasses they dont know what the fuck they are talking about. i get a range of about 200 miles per 12 gallon fill in my hoverwings. also when they talk about the craft jumping about half its wingspan,as long as you know what the fuck your doing its fine, ur not gonna stall like the dipshit says, ur not gonna flip,furthermore if u dont have real flight experence with these then STFU!!!

[ArubaSailing]

215% comperde to free aire-plane.

Is there more backing on this statemeant?

[brido88]

Search the russian ekranoplanes and do a bit of reading.

It's a fact they need less power for lift.

It's a fact they can go at speeds similar to aircraft.

[ajjs02]

if the wing span were increased then the amount of alt could be extened possibly? & computer sensory in the wing could warn of impending stall?it could also be done more cost effectively with vacume pitot tubes?

[jerseyflex238]

russian wigboat bluedolphin is way more more efficient suposed 2 get diesel engines and could fly over waves) prototype is ivolga)

[ccacace1]

like many of the high-speed hover-crafts in use around the world today you can only run them in good calm waters. In Italy they've using passenger foil crafts successfully for many years between Naples and the islands in the gulf. I believe they are using the WIG in Germany right now.

[Imprezaman555]

but hover crafts aren't very efficient. just fast. these are efficient and fast. also, these fly much higher than hovercraft. they can pass over much rougher seas.

[TacticusPrime]

hmmm, so i wonder what would happen if there was a storm? The swell wouldn't be too much of a problem, it could just fly a bit higher and have its range reduced. But some super strong winds? if that thing hits turbulence it might clip the waves. Then you're screwed. Or not? I'd like to hear more.

[Wh4tsit]

cool. I want one... how hard is it to build one?

[deauzie]

how much ?

[wonderfulskirt]

how much does one cost?

[wonderfulskirt]

excellent thing. can it fly really high or are there limits?

[sslavi]

Some of them can, some of them can't - it depends on what they've been designed for. This one, for example, can jump up at max. 1/2 of it's wing span - like they said it in the video.

In order to fly high they need more power then necessary for the in-ground-effect operation, and they became less efficient and competitive with airplanes or helicopters.

So generaly they are designed with the ability to jump over small obstacles only. That's usually more than enough.

[Klabautair]

Actually the bigger problem is the increasing instability when flying higher than half wingspan. The center of lift shifts forward when coming out of ground effect, thus producing a pitch-up moment that - in worst case - can lead to a total loss of control: the craft pitches up rapidly to very high angles of attack with a subsequent stall and hard crash.

That's the biggest challenge during development besides having enough power to get over the hump drag during takeoff run.

[krbosak]

Klabautair, indeed, this pitch-crash is considered to be the reason of crash of russian ekranoplan monsters many years ago.

[jannej312]

Maybe nobody wants to fly so low if the weather gets bad?

[jew4lyfe]

@jannej312 lmfao... its because in ground effect theres like no drag, so its supper inexpensive to fly these... in the simplest form of course

[mysteryMachinePL]

@jannej312 Its not bad after all, and economic advantage is huge (fuel consumption/capacity). They will never "protect" their pattents with forwarding air under craft... Soviets invent this before this company did. They are just another company that think they invented the wheel.

[QuartuvLarry]

Why the hell aren't there more of them?

[krbosak]

Despite what they say their problem is obstacle avoidance. The are not very compatible with dense shipborne traffic, f.ex. with yahts.

[QuartuvLarry]

I see your point. Tall ships could especially be a problem.

[a1coho1]

30+ years ago pioneered and perfected by Russians. Now there are, at least, 2 small and 1 large Russian companies building such crafts.

[mikesakas]

About 20 years ago.. this is NO news flash.. The have been used for decades

[ericplloyd]

These are sooo cool.  We already have the C&O canal here in DC, USA. I wonder if it'd work on that...

[aerocat22]

Thanks for sharing this video. Very interesting and I hope this product is used more throughout the world.

[100MPG]

When will the ECO-nomic advantages of WIGEC machines be rcognised?
