SCHOOL COMBINE

SCHOOL COMBINEA cozy little Latvian village, curly half-hidden by the green trees, densely interspersed as flat as a table field. They are spaced from each other sometimes just for a few miles, as the village of Ruda and Nice in the liepāja district, and their life is closely connected in such a close proximity. As many students, after graduating from the eight, ninth and tenth classes have been going to the Nica — high school there. No wonder collaboration rudskoy and Nicky Yunykh TEKHNIKOV — harvester “thresher-winnower” — known as RN-1: capital letters in the title villages. Built this unit in the circle of mechanization of agriculture, which is headed by teacher, physics, drawing both L. A. schools Ditka.

IL-4 ELECTRO

IL-4 ELECTROThis unusual model was built by members of syt Berezniki, Perm region. Copy flies perfectly, performs such demonstrations as “flying under the 45° angle” and “pipeline.” Remote speed adjustment of electric motors allows the model to freely come to the “stopover” and after run on the ground again soar into the air so that sometimes it seems — before you the real Il-4. With the design of the copy you are acquainted the head of the aeromodelling circle N. YAKIMOV.

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.

PLUG OF EPOXY

When fails the “proprietary” socket or the plug, replace it first got under a hand not worth it. It is possible to make an exact copy of this electroelements, virtually indistinguishable from the original. First, we need to make a matrix into a cell from sheet metal to kalit to half epoxy resin and plunge Read more…

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.
