Modern style requires decorating items of furniture, fittings, apartment interior repetitive, intricate configuration of parts; often the enthusiasts to undertake their carved from soft wood, bend metal strips, minted copper. But modern chemistry has given us such great works to such material, like plastic. Enough to make a form — and any item can be repeated any number of times. Simple injection installation, it much easier and expedited the receipt of such “tripe”, designed for syut-2 city of Taganrog.
FOUNDRY… ON THE TABLE
The first flight of kites I started to build in 1978. Dozens of options are made over four years, helped to define the tests, experiments and subsequent revisions to the best form and arrangements of the wing, to learn the subtleties of the serpent and its behavior in various conditions. All this allowed the “Acrobat” to become a highly maneuverable aircraft with high aerodynamic characteristics. Its design is highly durable. Snakes can fly in any weather, he’s good and confident performs aerobatics in almost any wind (4 to 16 m/s).
What models of gliders was not in the sky above the sports airfields! Short-tailed side by side with these, whose stabilizer it seemed unreasonably far related from the wing, the search of the optimal elongation of the supporting planes of the transformed outline of the airframe in the likeness of a flying ribbon, brachypterous, such aircraft unit. A few years ago, athletes arrived to a common opinion. Although each scheme had its own advantages and disadvantages, experimentally found the best dimensions that satisfy the conditions of soaring in thermals, the flight in a calm atmosphere and in a strong wind. Parameters recognized compromise (wingspan 2000 mm, chord 145-150 mm, shoulder 700— 740 mm), provided smooth, very good results.
Good motorists! Easy turn of the ignition key and the starter turning the crankshaft starts the engine. Of course, we do not encourage modelers to install an electric starter on the motors. We will focus on stationary unit intended to significantly facilitate the launch of the compression and glow model engines. He will provide you great help in training and in competition where the engine run time is extremely limited.
The most interesting, favorite books deteriorate in the first place. And how to get textbooks: students receives their classes for free, but at the end of the year should return, because their use is designed for 5 years. Extend the life of books can anyone, even a child, if he be accustomed to it and help to make a simple fixture. Among them the most necessary — press.
We have already talked about the agricultural arrangements, where the engine used electric mowers — rotary and shearers knife (see No. 9 of 1980, No. 2, 1981), plough on electric (see # 9 in 1981). Now offering new construction on the same basis — the cultivator of the soil. First, obviously, you need to explain why I designed the mechanism, the main purpose of which is plowing and this scheme — in the form of electrodyalisis. Why not go for more or less beaten path, taking up a walk-behind plow. First of all, it dictated the small size of the treated area and high density of planting tillers are simply not to turn around. Then had to take into account the weight of the guns and power, developing a medium amount of torque just 3 kg. With this machine will easily cope and teenager and woman, and elderly people.
