Despite the *really* weird appearance, those should be in the Modern Air board: those are all Soviet ekranoplan, or Wing-in-Ground-Effect birds. I really need a few more photos of the top two, I have some 'hovertanks' in mind that are really WiGE/direct-thrust vehicles. |

Oh!. My fault, I mistake the link.
Sorry for that. Amicalement

I don't mind he posted them here… Those things are AWESOME. Whatever happened to them? The designs are beautiful in their ruggedness! I love the 8 engines in a row up front. Rolando |

I agree with Lion of the Stars – they should be in the modern Russian Aircraft Board. However in defence of Armand I had actually labelled them Water Based for simplicity sake and to include other craft and images taken at the IPMS Show, Telford last year. the first is a Beriev WA-14 MIP and the remaining three all Ekranoplanes – see Wiki for more info.

A lot of what happened is that they're expensive. They don't have the capacity of a real ship, but they're as big as one. IIRC, the Beriev WA14 was supposed to be an ASW/SAR flying boat. Those two forward engines are just asking to get flooded out, but you need them running to help build the high-pressure bubble you fly on. Either the second or the fourth bird was supposed to be a cross between a cargo plane and a landing ship. Possibly both. Obviously the third monster is an even faster missile boat. |

Those are not planes, but are called a "WIG" boats, which stands for "wings in ground effect". They look like aircraft but act like hovercraft, although at a much faster speed. The one thing that isn't being mentioned is that if you have smooth enough ground, those vehicles perform just as well on land as on water. The catch being they can't get above 10 feet or so (at very best), so going over obstacles is pretty hard. The Japanese have a design for a WIG train, as a alternative to a maglev train. link |

Ok, from the top: Beriev VVA-14 (prototype), A-90 Orlyonok (few built), Lun-class (1 built), and the daddy of them all, the Caspian Sea Monster (prototype). The height of your ground effect depends on your wingspan, but WiGE are usually set up to cruise ~10-20m above the surface. Some designs can take short 'hops' over obstacles, but that's at the cost of quite a bit of range. The Beriev VVA14 looks like it has big enough wings that it could truly fly, but it would be most efficient very close to the water. Just about perfect for a subhunter using MAD (which is exactly what it was designed to be). Have you ever seen pelicans just glide effortlessly across the top of the water? That's ground effect. Once you get off the water, it's very efficient. Ground-effect is actually more efficient than flying high, although people usually use that efficiency to carry a much heavier load. |
