the sea plane has less drag on air than the hovercraft simply because of aerodynamics, however the hovercraft has less drag on water and land than the sea plane.
a chevy v6 engine that only makes 250hp? okay fair enough must be an engine from a rather old car. but its supercharged? how does it only produce that much HP
I wonder why UH use fabric sheet wings? They may be lighter and easier to transport but it means they are operating at a higher Angle of Attack than usual and burning more fuel as a result. We're starting to build a hoverwing over here in the UK, but on our test model, we're using foam-cored wings and when we get it level in gound effect, we can reduce the motor RPM by quite a lot.
As they say , give a brick enough power and it will fly. As far as I can see with this vehicle the angle of attack is too big and so it has a lot of drag and this is proven by the fact that the engine thrust has a large downward vector to lift the weight rather than push the craft forward. Given enough power anything will fly and I do not consider this an optimised design. For two people to fly like this but in an optimised fashion I would assume a good 50 HP engine would be a good enough. Still it is a nice project for many people to experiment with. Sometimes I wonder if it would be better to cut slots in the upper profile of the wing starting where the high pressure stops and the low pressure starts and use the air flow from the propeller fan to blow air through the wing slots on the upper section where the flow would be directed backwards hence it would not only push the craft forward but since it creates lift at slower craft speed the vehicle may rise at a slower speed . So while the air cushions blows under the wing, the directed air flow through the upper slots in the wing will result in a blown wing using the engine power to make what I would call an active wing and not a passive one. There is so much to do in t his world but so little time to do it all.
250 HP Chevy V8 engine? Supercharged? Seems to be incorrect ….This is why you cannot trust journalists… I did google this, seems to be more accurate. "Thrust engine 4-stroke, 241 hp, four cylinder, supercharged, liquid cooled, fuel injected, electric start" http://hovercraft.com/content/index.php?main_page=index&cPath=1_2_149
This is the dangerous model, a stiff wind will flip it over. An to do what I saw would take a strong engine. It's a waste if it gets flipped. What price are we talking about. They keep forgetting the price range. We are not made of money.
The us military owns that? Yeah that sounds like bullshit. Every video i see this woman in seems to have made up info. Next you'll tell me the stereo is military issue and only plays stars and stripes forever. Hell, why not complete the lie and say the seals use it.
I don't see the advantage of this over high-speed hovercraft. it seems this one takes a lot of fuel to fly a few feet. but she's definitely hot though.
There are plane that do the same, Russia built on years ago cant he be more original or make a business of it? it is easy to make a one or two anything, see Faraday Future!
first
thats the kind of boat/hovercraft batman would own
is this for milita3y?
Considering the noise level, why put in a stereo?
Shes beautiful ! 👌✋

Isn't this based on an old soviet design?

An ekranoplane eh?

VERY VERY VERY VERY COOL😎👍🖒👍🖒👍🖒👍🖒👍🖒👍🖒10X

@2:14 – "… and if the vibration, noise and nerves weren't enough to scare the pants off me, I have some alarming news …"
I'm all ears, Honey! 🙂
They picked poor examples to show. It is just a poorly made ground effects craft with hovercraft fans as landing gear basically.
Wow she look good 😻😻😻

More powerful than the Lun-class ekranoplan with 8× Kuznetsov NK-87 turbojet engines and a 100 tonnes capacity?
1:44 US military owns that!?!?
Love this. How much would something like this cost?
worthless
Doesn't appear to be stable or balanced. Lots of nose lift. Newer designs have taller T tails similar to business jets.

@3:10 proves that this vehicle is shit. Can the pilot be much more tense than this? He looks like he's riding a bull.
