The Next Spruce Goose

Check out: this site. Note that, unlike the Soviet WIGE, this version can take to altitude above rough seas or dry land."

  1. Russia already built this by austad · · Score: 5, Informative

    Back in 1960, the Russians developed the Ekranoplan. We saw it in satellite photos because the thing was too damn big to fit inside a building. It was over 2 football fields long, weighed over 540 tons, and could reach speeds of more than 500 knots. It could also fly up to 20 meters above the surface. Back in the early 1990's, we finally found out what that thing in the pictures actually was. Around 20 of them were built, but for some reason they cancelled the program.

    There's a good picture and some info here. The History channel had a show on this thing a few weeks ago too, and it made me wonder why we didn't have anything like that. It's an unbelievably fast and efficient way to carry large amounts of people and cargo.

    What happens when a engine fails
    Same as any other plane: it slows down a bit. Look at the picture, it's got at least 4 engines (assuming they're not using coax props with multiple engines in each nacelle). If one packs up, it's not a major problem.
    There is no margin for error.
    Yes there is. 20 feet, at least :). Seriously, when it's cruising, it's not going to be running at full power, so they just throttle the others up a bit, and put up with any loss of speed.
    What about rogue waves? It's crusing at 20 feet, and a 40 foot wave pops up?
    The document says "as low as 20 feet". If the weather's a bit ropy, they fly a little higher.
    For that matter, how calm does the ocean need to be for the ground effect to work?
    Not very. What counts is how high your wing is above the "ground". The ground effect starts to be measurable at an altitude of half your wingspan. For it to really work, you want to be somewhat lower. If the ocean is really rough, things will get rather bumpy, though. This thing is projected to have a wingspan of something like 150 metres. That's BIG. It would be getting serious groung effect with its wing 20 metres above the water. That's 65 feet, folks.
