X all-Union week of science, technology and production for children and youth, held in January 1983 in the Uzbek capital, has raised a lot of interesting developments from many cities of the Soviet Union. Including all the way from Tashkent. Specialists, participants and guests of the week were memorable examples of vehicle technology, presented the laboratory “Avtokonstruktor” Tashkent gorsyut. In particular, the moped “the cotton-grower-S-83”, intended for people in rural areas.
MOPED “COTTON GROWER”
Walk-behind self-built eager to make the most versatile. This is understandable: it has to perform a variety of agricultural operations. However, to create a design that is most optimal for any work at the farm, is not easy. So, powerful, heavy duty motor-plow, as a rule, is too broad and clumsy in the aisle, and brisk the tiller can’t beat plowing the dense earth. One solution to this problem is offering our reader from Krasnodar territory Vladimir Yakovlev. Its compact one-wheeled tillers will assist in the processing of the beds, will not damage plants close together and, if necessary, in just 10 minutes will turn into two-wheeled motor-plow.
We present rocketmodeler development contains many non-traditional solutions. I hope that they will interest the creators of “microcosmic” technology of today and will be useful to those designing models for the future sports season.
In the “M-K” No. 8 for 1984, we talked about the greenhouse arch designs made by students of the Bauman district of Moscow. Its main load-bearing elements — the half-arches — been made of gymnastic hoops. This circumstance is strictly determined size of the greenhouse. But it is tempting to build on the same principle a more spacious and convenient in maintenance construction of a greenhouse. But here’s the problem: the material for poludov frame to find easy.
To prepare starch from potatoes at home I have several years helps… washing machine “Kama”. To turn it into productive avometers needed very little improvement. From a round steel plate d 189 mm and thickness of 0.5 mm did scratch the disk, propertyreal his thick nail So that the disc is not deformed, sawal-Deval edge, and the holes are filled evenly deposited on the workpiece concentric circles. Took the car activator, secured PA the disc grater on six M3 bolts with countersunk heads and set back. From thick durable Board, cut out the partition, the spacer wedge and cover the boot compartment.
Case microsociety class S6A (Fig. 1) champion 1986 A. mityureva formed of two layers of fiberglass with a thickness of 0.025 mm and subsequent treatment with sandpaper. The mandrel of variable cross section, largest Ø 18 mm, and a minimum of 13.2 mm. Aft of the case is tapered, with the last 7 mm of the length it is cylindrical, above — the length of 30 mm to a transition cone. The length of the main cylindrical portion 89 mm, the bottom glued the balsa frame with a hole beneath the engine. This provides accurate setting of MRD. The frame is made of a radial hole for fixing studs of the engine. Stabilizers balsa, with a thickness of 0,7 mm. the lateral side reinforced with fiberglass. Fairing fiberglass. It is pasted inside a frame. Join the corps — through mounted in the spinner.
In which only the terms will not be during the journey of the lovers of water tourism! And not always the boat suitable for sailing in a pond, suitable for another.
The idea of vertical garden beds is not new, however this design is very reminiscent of a step-ladder, always a surprise even experienced gardeners. She designed the Moscow schoolchildren Pavel Vasiliev and Mikhail Zinoviev, working in the Palace of pioneers and pupils named after N. K. Krupskaya, and not once was it possible to obtain stable high yields.
It is not easy to be “protanium”! As in any other class of modeling, the success of his performance depends on the number of workouts. And how to look forward to the end of the long winter to come up with a model for the wet melting snow from the track and begin a new sports season! He flies quickly: in only five months. The rest of the year can only be used for the construction of new equipment. So if we had to continue training all year round! But it is hampered and the lack of winter sites suitable for starting, and poor performance nitro engines in the cold. And the use of such “exercises” stiff arm a little.
Today we introduce modelers-students with two versions of microart class P. the Elegance of the external lines, simplicity of design and manufacture — this is an incomplete list of advantages of these models, designed and built by young athletes Moldovan CSUT under the guidance of an experienced teacher, a veteran of labour and fleet D. Vysheslavsky. Using new technology, children have made significant weight reduction of the housings and the models themselves. Steel yachts virtually unsinkable, increased their rapidity. As soon as the young modelers have gained experience of commissioning models and the ability to feel the weather, the performances microparasite this type of steel to bring them consistent success on the scoring starts.
