What can replace the WIG?

History knows many mind-blowing projects, surprising his own courage and complete isolation from reality.
Submarine aircraft carriers (with the submarine seaplane — used in Japan for the symbolic "bombing" forests of Oregon).
Amphibious flying up vertically VVA-14. Mind-blowing machine for beauty. However, it remained unclear why amphibians vertical takeoff, when around — an endless expanse of aqua, applicable as of the runway.

"Pocket Pistol" for strategic bombers B-36. Mini Fighter XF-85 "Goblin", hung in the bomb bay and produced in the event of enemy aircraft. Crazy from the beginning to the end of the project, but smogshy grow to the stage of flight tests.

And, of course, WIG — one more determined attempt to fool the laws of nature. Unique design, combines within itself "speed characteristics of aircraft with conventional ships carrying capacity" that can "move over water and hard surface" and "has broad prospects in the field of passenger and shipping, rescue people in distress at sea, as well — as a military ton for the transportation of troops or carrying cruise missiles. " Unfortunately, all of the above advantages WIG — incorrect information, widely publicized in the vast web. WIG has none of these parameters.

A comparison with the winged ship quite unnecessarily — the largest of the constructed "monsters" are inferior in capacity, even languid transport planes and ships against the generally look like small luxury boats. Equally unfounded comparison with winged aircraft — aircraft fly two to three times faster. The last argument — the possibility of flying over the smooth, hard surface (land, snow, ice) can cause confusion among passengers Tu-154 or IL-96 — the aircraft in principle indifferent relief under the wing. Taiga, mountains, ocean …

This just to make certain instances — in the process of the discussions, "ground effect" we once watched curious scene:

— transport WIG "Eaglet" and "Caspian Sea Monster" on the pieces lost to the transport aircraft AN-12, AN-22 and AN-124 on the aspects of "speed, price, range transport", also on a range of implementation and ensure the safety of the flight. The same applies to the unrealized South American project "Pelican" — victory of technology over common sense;

— comparison of combat WIG "Lun" with the ships of the Navy, too, did not work out in favor of "goose-unicorn" — freshly baked "aircraft carrier killer" was completely defenseless machine with the least impact potential. In these criteria over the highest rate of WIG (in the best case — 600 km / h) does not make any difference — for a modern jet aircraft "Lun" and destroyer prototype static objects. Only the latter can stand up for themselves and fighting WIG — no (if set to "Lun" naval SAM — supercharged monster just will not be able to rise into the air.)

— equally without result was comparison Combat WIG "Lun" supersonic bomber Tu-22 and Tu-22M — a tremendous low-speed machine with a tiny combat radius looked flying embarrassment against missile Tupolev. Vpribavok "Lun" appeared prepyadstviya with target designation — floating at the surface of the water, he beheld nothing on his nose (radio horizon 20 km). And, after all, cheap, very cheap! — Which only cost 8 jet engines NK-87 shot with a wide-bodied Airbus passenger IL-86.

— for the same reasons was utopian idea rescue WIG. "Guseedinorog" simply will not be able to find the victims of the crash because of their own low-altitude flight. In addition, a very small range (2,000 km) — in spite of all dreams, winged "Rescue" is not able to rescue the crew of the boat "Komsomolets" sank in the Norwegian Sea.

"Caspian Sea Monster"

Netseleobraznost built-winged monsters become clear for another step of their design. The main premise of failures designer Rostislav Alexeyev — fundamental natural prohibitions: a very large density of air in the lower layers of the atmosphere, as trivial difficulties taking off from the surface of the water — to overcome the terrible resistance (draft WIG — a few meters!) And the forces of "sticking" to the body of water "Caspian monsters "required propulsion power indescribable (CM — 10 (10!) jet engines RD-7, taken from the Tu-22 bombers. consumption on the rise — 30 tons of kerosene!). These characteristics are, of course, put an end to the career of the forthcoming "goose-unicorns."

Justification related to the shortcoming of time and money in Alekseev to improve the designs of their own, do not have a real reason: the first aviators familiarity with the display effect (appearance under the wing of a dynamic "air cushion" in flight near the surface of the shield) was published in the 20 — years of the last century. Rostislav Alexeyev was seriously engaged in the topic since the 50s, the work went so well that by 1966 in the air rose indescribable 500-ton "Caspian Sea Monster". This construct was impossible to recreate in makeshift criteria, construction of the "monster" that claimed the enormous efforts of a research and production team. Everything was going great until that time, had not yet been received discouraging test results. The result — built only about 10 "monsters" for various purposes (including models and skeletons of unfinished).

For comparison — helicopter: if you do not take into account the unique designs of Leonardo Da Vinci's helicopter got a start in life in 1911, when engineer Boris Yuriev invented the swash of the blades. First flight to the "helicopter" began in 1920, each time getting faster, further and more confident. The limited application of the second world war — and the triumphant rise of helicopters during the Korean War. There is nothing to add — the helicopter had a really amazing properties.

Another "goose-unicorn" does not fall on the museum


Visit the web site "Military Review" fair drew attention to the existence of a large number of home-made airfoil designs made by enthusiasts around the world. At the moment, WIG — as before which is popular topic, virtually every exhibit of aviation and marine technology can meet the shield with the models of these machines and colorful booklets that describe the properties of their outrageous and efficiency. This is probably a good reason …

Neuzh something light WIG — that sought has a niche for implementing this type of technology?

Invite readers to spend a short comparison of 3 cars:
— Modern winged Oriole EC-12P (2000)
— old "maize" An-2 (1947)
— famous helicopter UH-1 "Iroquois" (1956).

What can replace the WIG?

At first glance, looks very easy winged presentable — not yielding to light aviation in speed and capacity, he has no equal in terms of fuel economy. But first memory is deceptive, An-2 helicopter "Iroquois" is quite old machines, for example, to "for maize" is set engine AL-62, made even in the far 1937 on the basis of a license, "Wright-Cyclone". Replace the "Orioles" instead of BMW's modern engines slider from "emki" and gaze as swap machine properties. And do not forget to make allowances for the archaic structure of the An-2 — no composites, plastics, and the rest of the high-tech. Languid (but a cheap and strong) main landing gear wheels of the Il-2. Not the most high-quality build and aerodynamics. Passengers winged "Oriole" sit in a chair, leaning shoulder to shoulder — passengers An-2, in contrast, are free to get up and walk to the end of the cabin, where on the 15th of frames installed plumbing system of the "bucket" — no small thing, given the "turbulence" in-flight "maize" near the surface of the earth.

Cessna-172 with a modern "tuning"

To be fair, you can see a more modern light- plane "Cessna-172" (first flight — 1955) "Cessna" can not be directly associated with the An-2, as This aircraft is in a totally different weight category (maximum take-off weight — a bit more than a ton.) All the same, it can be some correlation between the performance characteristics "Orioles", "maize" and "Cessna".

"Cessna-172" carry up to 4 people (including the pilot) and is able to cover a distance of 1,300 km with a cruising speed of 220 km / h The power plant — the only 4-cylinder engine capacity of 160 hp The supplies of fuel on board — 212 l .. "Cessna-172" has shown very good properties, which, together with the simplicity, reliability, and low cost to provide her global success. As a result — a small "Cessna" has become the most popular aircraft in aviation history.

From all of this comparison should nezamudreny conclusion: light WIG can quite successfully compete with small-engine aircraft. Small in size, not a bad aerodynamics and low-speed flight level out all the flaws inherent in a large "Caspian Sea Monster" and provide better fuel efficiency. Disadvantages machine — its cost (rather estimate the cost of servicing the 2-12-cylinder engines of the BMW 7-Series) and the introduction of a bounded domain associated with aqua seats (for the most daring — snow-covered tundra without palisades and lines of power transmission lines). Verdict — the machine on the fan.

These flying boats represent a new level of equipment, designed to strengthen our defense capabilities. They are not creepy waves, and they are able to fly very smallish at high speed, which makes them virtually imperceptible.
Ahmad Vahidi, Iran's defense minister

Very fascinating history associated with the creation of WIG in Iran — a couple of years back, it became clear that the protection of the Islamic Revolution have adopted three squadrons of flying boats — light single airfoil type «Bavar-2" ("confidence" in Farsi). Iranian machines feature a Triangle wing — the result of the work of German aircraft designer Alexander Lippisch, who dealt with the problem of "ground effect" along with Rostislav Alexeyev.

Works Lippisch were well known throughout the world, including the Soviet Union. Another early 80-ies of Russian enthusiasts have designed an easy flying boat, the design of which is directly to the individual parts of the absolutely identical to the structure «Bavar-2". The Iranians only nekordinalno upgraded winged, replacing the propeller pulling the push and possibly equipped with machine gun and its special gear (according to official figures, «Bavar-2 'armed with a machine gun).

Of the unique parameters «Bavar-2" — the highest secrecy. For the South American Iranian navy winged as elusive Joe that no one finds, as he broke. Jokes jokes, but if the body «Bavar-2" is made of wood, plastic or other radio-transparent materials, the detection of small targets is converted to a really complicated puzzle. Another thing is that single light combat vehicle does not represent any danger to the ships of the enemy … However, in the presence of desperate men, mosquito fleet can be used for reconnaissance and sabotage of similar attacks on tankers during the Iran-Iraq war (1980-1988 gg. )

In the end I would like to tell an optimistic story connected with the creation of a high-speed passenger ship gliding A145 project. Modern Russian development, embodied in the metal at Zelenodol'sk shipyard. The vessel launched in May 2012.

What can replace the WIG?

A145 craft project is designed to carry 150 passengers with luggage at a speed of 40 knots at a distance of 200 miles in the daytime in the coastal marine area. Seaworthy properties of high-speed passenger vessel allow operation at sea up to 5 points. Total displacement of the vessel type A145 — 82 tons, engine — two MTU diesel engines to 2000 hp each.

On board the new passenger ship is provided with a fairly high level of comfort, including the expense of rational assembly and a spacious lounge with multimedia system, comfort seats, Kondyukov, 3 toilets, catering passengers on board.

In fact, I gave an example of this masterpiece of shipbuilding, to show to you as economical vehicle compared with ekranoplan. The planing vessel type A145 had 2-diesels with total capacity of 4000 hp Ekranoplane "Eaglet" at the time it took marching turboprop engine NK-12 capacity of 15 thousand horsepower, plus two turbo-NC-8, taken from the passenger Tu-154.
When a similar capacity (20 tons, 150 Marines) glorious offspring of Rostislav Alexeyev was twice as big and was spending 28 tons of kerosene for 1,500 kilometers. The differenc
e in price liters of jet fuel and diesel fuel can be neglected.
