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.
VASE IN THREE FLOORS
In fact, the “floors” can be very different, as well as the selection of plates and saucers, depending on the purpose: fruit, berries, candies. It is important that all suitable options proposed the principle of multilayer Assembly. The base vase is a long bolt M4 flat-hat; however, an other solution, say, using the wheel spokes. Read more…
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.

During transportation the “scoop” is placed on the bar-stop.
Operation of the first single-seat Ka-8 and Ka-10, created in OKB N. And. Kamov, showed obvious advantages of coaxial-rotor. Along with the compact that was excellent handling and maneuverability, the ability to make takeoffs and landings in difficult conditions, which has opened up opportunities for the use of helicopters of this type.
