In 1966, the Commission on space models of the International aeronautical Federation (FAI) has developed a code of sport in which raketoplana divided into four classes and assigned a so-called “bird” names “Sparrow”, “swift”, “eagle” and “Condor”. On the amended in 1975 and 1989 the FAI code partition models raketoplana into categories and classes depending on the total impulse of the engine and the starting mass was clarified requirements for each category, classes are five, and since 2001 to six. Today we will talk about the category of raketoplana S4 — models of gliders with the accelerator Category is subdivided into six classes the Most popular class S4A — promised.
Not always, kindergartens or nursery located close to the poma. Wearing the baby to the bus or tram on the runes hard, especially in winter. To enter a vehicle with a child and a sled uncomfortable. This situation gave me the idea to make a lightweight collapsible sled. Experience has shown that the design turned out well, lightweight (weighs only 3 kg), simple enough that the kid feels for them perfectly because the seat is made in the form of a chair.
The characteristic trend is clearly revealed held in the summer of 1978 the VI all-Russian meeting of young rationalizers and engineers: in many rural schools children are actively engaged in the mechanization of labor on their educational sites. At the gathering, devoted to the 60th anniversary of the Lenin Komsomol young technicians from many regions and republics brought all kinds of tools and machines to facilitate agricultural labor. From motociclo and matatapos to small tractors of various schemes and designs is the range of the current Hobbies of students in rural (rural!) schools.
Looking at this unusual aredigital, could not help thinking that he was inspired by the famous Swedish writer Astrid Lindgren for creating well-known children’s story “Karlson on the roof”. The kids loved the kid Carlson, and not the last role in this played the “technical equipment” lover of raspberry jam — it is famous for the motor with the button on his belly…
Design and manufacture of midget cars is one of the popular directions of technical creativity. This can be judged by the growing number of automodular presented at various technical exhibitions. Unfortunately, many of the infantile groups you have to “Torito” own way, repeating the mistakes of predecessors, not taking advantage of their good experience. In today’s post attempts to summarize the experience of autocostruzione in the laboratory of experimental modeling of the club of young technicians of the Siberian branch of the USSR Academy of Sciences.
In No. 10 for the year 2007 was published material designer homebrew A. Knyazeva from the city of Rasskazovo of the Tambov area made them a few snowmobiles. More detail in the publication was lighted the fifth design with the engine M-11FR from the Yak-18U, cabin and ski from the Yak-12. Today the author talks about his sixth, and as he says, the most successful design.
Aeromodelling laboratory at the club of young technicians Kakhovka plant of concrete products of 50 years of the USSR created three years ago. Began to engage in a small room of an ordinary house, and now CUT has a spacious, bright room in the new Palace of culture “Improver”, has all the necessary equipment, machines, tools. Here is the first in Kherson region the track, which now hosts all regional competitions on aviamodelling sports. Last year in Kakhovka took place championship of Ukraine on kordovy the aircraft.
Probably, many motorists familiar with this situation: after a continuous drive for a distance of 200 — 300 km of the right leg begins to resemble what it is and what it is time for her to relax. Although it is necessary to go for a long time. For the rest of the legs during long trips propose to install in the car simple device. Conventionally, I called it “autopilot”, as it was able to maintain the set speed when driving on a flat road. Moreover, in the case of the overtaking allows you to add “gas” and then again remove the foot off the pedal the vehicle will continue moving with the same pre-set speed. Turned off the device instantly, you only slightly press the brake pedal.
The development of specialized agricultural systems is unthinkable without the complete mechanization of manual labor. Many vegetable) crops do not require manual labor for their cultivation and harvest. But the stumbling block to this remains the mechanization of harvesting cabbage. Not developed cabbage harvester our industry. So we have in ancient times to strike each head, to put in baskets or bags, and then load the trucks. And all by hand.
