Say what you like about the Russians, but their inventors are very talented as has been proved time and again.
Humm, ekranoplans (Screen Planes in English), also know in the west as WIG's (Wing In Ground effect) Russian's built a number of them, including a few really big ones one of which was called the Caspian Sea Monster. Russians had a number of ideas for their use, like high speed long range landing craft (carried 1000 troops) or as an anti ship platform, picture of which is on this
Link. (One had six very large naval anti ship missiles in launch tubes mounted above the fuselage, with guidance and targeting radars on the top of the tail. I’ve seen footage of one of the missile fired from the aircraft while in flight). On the video of the big one on that link (with 10 engines), the 8 engines at the front were just there to get the thing airborne. Once in ground effect, all of them were shut down and the ekranoplan cruised on the two engines mounted on the tail. The smaller ones with 8 engines, just shut some of them down (the info on the pravda link is wrong, no surprise there) One of the reasons the thing could travel for miles with a very heavy load. However they do have control problems, and cannot deal with a heavy sea swell. Yes, the Russians have always been good at Hydrodynamics and Aerodynamics thanks to the Soviet Union setting up a research and educational institute just for those two subjects (known as the CENTRAL AEROHYDRODYNAMICS INSTITUTE (
TsAGI)), which is still going today and was the first institute of its type in the world. Most of the top designers in the USSR/Russian Federation have come out of there, including I do believe, Rostislav Alexeev who came up with the idea of the ekranoplans. (As part of his work on high speed boats (overcame the cavitation speed limit of hydrofoils, which limits them to a maximum speed of about 80-100mph), which was the role of the Central Hydrofoil Design Bureau where he worked). Which means that the ekranoplans are actually classified as boats, if they cannot fly out of ground effect. (Though a Swedish one and the German Alexander Lippisch, also had the same idea, but went about it in a different way in that their designs could fly like a normal aircraft).
