Not for the first ten years there is a class of experimental aircraft. It would seem that this time is sufficient to clearly determine the best scheme inflected wing”, the most favorable profiles and types of balancing. But every new competitions at the Tushino airfield, gathering creative enthusiasts from all over the country, convinced that the search is not yet complete. And it is not surprising to achieve stable flight model “flying wing” in contrast to the classical devices are very difficult. Why so few “highs” in the tables of experimental results, although at first glance the benefits seem obvious tailless.ON ONE WING

Old Russian game gorodki beat always popular. Many fans of this popular sport attracts it today. Our reader A. Zhdanov from Feodosiya has developed its desktop version, which is no less dynamic, keeps its swashbuckling spirit of competition and excitement and allows you to play on a miniature field at any time of the year. Not accidentally, the table towns marked by a copyright certificate.
The prototype model has served as a snowmobile amphibian created in 60-ies a group of young professionals under the leadership of the Soviet aircraft designer A. N. Tupolev. This car attracts the severity of the contours (see “M-K” No. 11 of 1978), do not break any complex suspension system of the ski or tubular enclosure of the propeller. And this is a significant advantage Because each protruding element design increases the aerodynamic resistance. It is better to have a bulky, but streamlined body than compressed to the limit, but with the “stork” legs of the undercarriage. In addition, the housing of such a model creates the effect of aerodynamic unloading, manifested even at low speed. Amphibians have relatively small diameter propeller.
What do you notice? They again begin the dog more likely to catch the eye in the yards, on the streets of cities and towns, rural roads — nimble and fast two-wheeled machine with silver spokes. One time, at least in large cities — bikes were everywhere and, it seemed, irrevocably supplanted by multiplying by leaps and bounds with cars. Played a role and decreasing size of modern apartments. But the architects revised the plan, added to the rooms, balconies and loggias, and the designers created a folding bikes — and as a result today we can talk about the revival of popularity of this individual mode of transport.
Since 1983, the Federation of auto modeling sport of the USSR introduced the class E-2. It includes the simplest kordovye model cars with electric motor supplied from the outside! about current source. A new class immediately attracted the attention of young athletes. Simplicity of design, availability of materials and engines, the possibility of competition in every gym, even the school, equal conditions for all invaluable advantages, especially from the standpoint of the development of mass automodelisme. Because machines of this class no matter what the weather outside the Windows, in the village or in the city is a circle of aviamodelirovaniya.
Among the many ways of handling and cooking fresh fish at home hot Smoking unjustly occupies one of last places. Although lovers to taste the “kopoushka” a lot, accompanying her cooking smoke seems to many an insurmountable obstacle to the application of this method in the conditions of city apartment.
