    Autoreply,

    Yes, he has a question about deltas that are like the Sea-Era. He is giving examples that he thinks are close to Sea-Era is my guess.

    wide wing over water

    Rohr 2-175

    it seems to me interestingly

    Interesting. Looks like some serious work went into it.

    The hover craft hull is much different than the flat bottom hull on the Sea-Era.

    Who funds all this work? The communist party?

    Is this private money?

    Not sure these would make a good roadable seaplane, sure look good.

    qxev,

    Have them email me and we can get a design that would work for the USA and Russian markets and make some money. Must be roadable, though... Can anybody speak English or German?

    I am ready to help in this case

    all information which can be useful

    certainly, it should be transportable on the highway...

    and house storage in the container...

    the device was created by a modular principle when (центроплана, consoles, plumage, floats, a cabin, the power plant) it was possible to change a relative positioning of units in certain limits with the minimum constructive completions. Besides, loadings from all units became isolated on a power caisson центроплана (box) that allowed to create very easy and rigid design. Was decided to refuse from поддува as it reduced draft of the screw which and so catastrophically didn't suffice for running start. Therefore the MT-9 engine in capacity of 36 h.p. with a reducer and pushing screw in diameter placed from above центроплана. The take-off mass of the device made 280 kg, the area covered - 12 sq.m.

    [​IMG]

    The device showed good stability and controllability on modes as near the screen (10-20 cm from water), and far from it (to 10 m). When flying by a snake the angle of heel reached to 150, speed of flight - 110 km/h. V.G.Nosov who in the specialty was the aviation engineer, instead of the test pilot flied on экраноплане. During tests it became clear that to each height there is a range of speeds and angles of attack of steady movement. If speed of flight is small, the device didn't hold height, making dlinnoperiodichesky fluctuations at the screen, thus the dynamic airbag didn't allow ELA-13M to concern a water surface.

    Man, I wish Orion were here... :cry:

    Would love to hear his input on all of this interesting new material.

    qxev,

    What relation do you have to this airplane? Who makes it. Looks cool

    The numbers...comments if you will:

    1) 700 kg x 2.2 = 1540 lbs
    2) 210 kg x 2.2 =462 lbs
    3) Cruise 250 x .62 = 155 mph
    4) Max 300 x .62 = 186 mph
    5) 2 rotax 912 = 18l x 2 = 36l/hr /3.785 = 9.5

    What is the purpose of the design? Playing in water? Going places? Looks nice.

    The leading edge is what most people would think is good. We tried such a leading edge and the drag was much higher on the model than flat and sharp. The top surface of a delta should be small radius (not sharp for safety). Notice what the F-22 does on the forward cockpit. This design looks nice but may not do all that the skin area can do to aid lift and lower drag. This design suffers from high drag, just like our first Sea-Era High wing model did.

    The side by side twin as shown lead to very high drag and is hard to fly when the engine quits. I discuss it above in roadable must have.

    Why the wing bend?

    How much did it cost? Do you think it has a future? (My answer is no) Width is not going to work on roadable and garage.

    You can see up but not down well. Put the canopy on the bottom...for looking at fish in the water.

    my 2 cents:

    qxev,

    I can see how this would do WIG. The hull would catch and not glance off the water, however. Sea-Era uses flat sections and does not get the strong negative pitching moments that this hull would create. The air going around the lower nose will suck the nose down giving a negative Cm, whereas the flat panels of the Sea-Era give lift and a POSITIVE cm about the AC of the delta. The delta cm cancels out to some degree the cm of the wing, depending on size ratios, lowering trim drag allowing for high speeds.

    What is the mission of this airplane? How is it useful other than water landings?

    I carefully collect, and I analyze information on any new plane

    it is work of other group... the plane never flied. the model is made only

    now the project is frozen
    their producer was shot
    [​IMG]
    http://wn.com/blended_wing_body

    + the plane which has chassis on the air chamber....,

    it is exaggerated at a landing...., it is cleaned in flight (the rubber covering is stretched from inflating),



    attempt to use effect "a circular wing of a kaster"
    http://www.youtube.com/watch?v=6XQ-C8Jv8v0

    it is too much high technologies... new materials for the chassis are necessary (durability and elasticity) process of operational development will be long and painful
    the price of $150 000 for the plane is mentioned.

    this plane, just as ELA-13M tries to use "Brunelli's bearing fuselage"...,

    [​IMG]

    which is - to create the big power of transfer on small speed of flight

    landing speed of 65 kilometers per hour


    question - why?


    because carrying power create not only wings, but also a fuselage (the bearing case)

    smooth and safe landing

    [​IMG]
    planning from height on landing, the pilot feels that дископлан as though sits down on "pillow" and was automatically stabilized in cross-section section and longitudinal the directions. After that the device can already fly without intervention of the pilot to management. Also it is impossible to force to accelerate a glider landing while speed of flight, naturally, it will not be extinguished, and the effect of "pillow" won't disappear. After that "Diskoplan" will land independently - on three points of support. It is important, because even possible mistakes of the pilot at the moment of landing won't lead to unpleasant consequences.

    airplane-amphibian VVA-14 it was executed according to the high-plan scheme with strongly developed bearing central wing of small lengthening,

    [​IMG]
    At tests of amphibian VVA-14 (14М1П) it was established that the effect of a dynamic airbag was shown at heights big, than the theory predicted. At an average aerodynamic chord of 10,75 m this effect was felt from height of 10-12 m, and at height of alignment of 8 m the airbag was already so dense and steady that pilot Yu.Kupriyanov repeatedly asked the management to allow to throw the management handle that the car sat down independently.
