Weather service uses a variety of research methods. One of them is the distribution of atmospheric parameters on height. To quickly solve this problem scientists helps small uncontrollable meteorological rocket MMR-06 with solid engine. The maximum height of ascent is 60 km; the instrument complex allows to measure the temperature and pressure of the air to determine the wind velocity vector. Information transfer to the ground by the telemetry system.
Many of our readers may find useful and is available for self-production of the offered design, making rational and convenient to place and books “daily demand” — those that have to go often; and solid tomes or long-stored sets of journals; and current periodicals.
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.
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.
The command “Start!” and mixed performance on the race ahead on the highway. Very long lasting-in — 2-3 minutes, but during this time, the miniature machine will take hundreds of turns, each time changing the speed. You have to drastically drop it to moderate before the turn, and then give “full gas” at the straight portion.
Designing electronic devices on integrated circuits, radio Amateurs often use to display the information indicators IN gas-1 — IN-16. They usually feed from the mains AC voltage of 220 V or from a separate winding of the transformer. Consequently, the instrument is “tied” to the grid and they can not be used in the field.
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.
Our homemade planer-“piece of iron” compares favorably with industrial: twice easier, simpler constructively, quickly and accurately adjusted. If you make a few of these tools, they can be successfully used at the lessons of labor in school. Students easily master the work with homemade.
For applying glue on the floor during the laying of linoleum can be done in just a few minutes from fanerki thickness 3…5 mm, cut it “comb”. Work will be more convenient, if the scraper to impose on the MOP handle.
