We left Russia and its underwater aspirations in a difficult moment for the country, alas, is only the first in suffering the twentieth century. Broke out in 1904, the Russo-Japanese war found Russia in a far-from-ready position. Moreover, these words can be attributed to the submarine fleet. Not just existed, there was even no development plans, no more or less suitable for “reproduction” prototype. However, the Naval Ministry had to sign an agreement with the former firm of Holland “electric boat”, for the construction at Nevsky shipyard in St. Petersburg a series of five more units in the fall of 1903. However, the chosen system (the hull was built in Russia, the equipment arrived from the US), quite reasonable for such a new business in peacetime, during the war, became a real brake. In the end, even the head “Pike” delivered to Vladivostok a few months after the fighting ended. Late to the boat from another American lake, also assembled in Russia under the scheme of peace. A similar fate befell an earlier project hollandskyi “Beluga”. The only submarine that arrived in the far East to the Tsushima defeat, became overbought at the lake’s “Protector”, aka “Sturgeon”. But he did not have time to act before the end of the war.

Many readers were interested in the material “Migomobile — fantasy? Reality!” (1977, No. 11), tells about an unusual engine for transport — the flywheel developed by a group of young enthusiasts, members of the NTTM. To meet the wishes of readers to continue this topic, we begin today the publication of a series of articles about the transport of tomorrow. To keep this section we asked doctor of technical Sciences Professor N. V. Gulia.
Wings of schematic models of gliders do not usually have a large margin and when tightened on the guard rails inexperienced athlete fall into a flutter or fold overload!
In a previous article under the heading “electronics for beginners” (see “M-K” № 8, 1979) we understand how magnetic field is formed it Turned out that, in particular, generates supplied to the coil (solenoid) electric current. The same field with a certain force acts on it carried to the magnet. But the magnet with the same force acts on the wire, which carries current. On the phenomenon of the interaction of electric current and magnet based electric motors (electric motors).
SOVIET CAR “MOSKVICH-408” ISSUED IN 1964. Youthful impressions sometimes impose their stereotypes on our lives. It’s funny that the “Moskvich-408” has remained in my mind a real car, and not his successor, “412”, hasn’t appeared six years later supermassive VAZ-2101 “Zhiguli”. And when in the early 1990-ies I was told that a car owner, a man very advanced in years, wants to sell the car “Moskvich-408ИЭ” low mileage, in General, with very few for that time’s money, I immediately agreed with the owner about the meeting.
The wig was created with the support of the “Arctic tergovernmental company” in Nizhny Novgorod. “Aquaglide-5” performed by the classical scheme of the aircraft with low-aspect-ratio wing and twin fins. To facilitate take-off unit and output on a hard surface under his wing to create a static air cushion by blowing air from two rotary propellers. About 85% of the lifting power of the apparatus is created by the wing, and the rest — due to the dynamic air cushion. This allows to automatically maintain the altitude.
