ON ONE WING

ONE WINGNot 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.

THE AMPHIBIAN ON THE ICE TRACK

AMPHIBIAN ON THE ICE TRACKThe 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.

THE MOST ENVIRONMENTALLY FRIENDLY TRANSPORT

THE MOST ENVIRONMENTALLY FRIENDLY TRANSPORTWhat 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.
