HOUSE FOR RABBITS

A HOME FOR RABBITSMany interesting developments have been conducted of the Komsomol all-Union competition of means of mechanization for agriculture. Under section livestock unanimous approval of the jury got the rabbit design mini-farm presented by production Association “Nevskaya Dubrovka” (Leningrad oblast), which produces furniture. Development plots for industrial enterprises and organizations is known to be an integral part of the Food program, adopted at the may (1982) Plenum of the Central Committee of the CPSU. In “Nevskaya Dubrovka”, assess their capabilities, decided to breed rabbits.
Isn’t it risky was that decision, when you consider that often even specialized rabbit farms are unprofitable? No. The Association had the results of years of experience and original designs of cells known breeder and inventor Igor N. Mikhailov, who gave the assurance: in the first year the construction of the farm will pay off and it will be profitable.

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.

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. 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.

IN LIGHT OF THE NEW RULES

IN LIGHT OF THE NEW RULESSince 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.

CAR-“SCOOP”

CARTo fill the wheelbarrow with sand, grain or leaves, it is not necessary to take in hands a shovel. Put it on… “scoop”. It is made from plywood, the bottom and sides are fastened dural corners, and the front rivet is a metal “toe”. Fixed design on the body with the latches 3 (window latches) and axis 4. During transportation the “scoop” is placed on the bar-stop.
