The design and construction of the “Bumblebee” creative team “Rise” was based on microalloy design V. Barkovsky, V. Vinitsky and Y. Rysuke described in “MK” (see: 1969, № 6, 1970, № 3, 1970, № 10 and 1971, No. 6). This well made and for the first time in the country is stable flying machine of this class was exhibited at the Central exhibition NTTM 74 and was awarded a silver medal VDNH. Schematic diagram, basic dimensions and technology are critical components of microstoria differ little from those recommended in these articles, so we will consider only the scheme of “Bumblebee” in three dimensions and focus on the changes that have been made in the process of finishing and flight testing of the apparatus. Outset: we had the opportunity to use a number of ready-made components and parts from decommissioned planes and helicopters, which, on the one hand, some changed the look of our machine, and with another — has greatly facilitated the work: eliminated many labor-intensive operations, used aircraft normal, good fasteners, and so on.
GLIDER-GYROPLANE “BUMBLEBEE”
Motonarty and all-terrain vehicles on tracks are very popular in areas with snowy winters and impassable for other land transport by road. Many Amateur designers to undertake independent production of such machines and even create original vehicles with high cross.
Tillers, mini-tractors, potato harvesters For economically strong farms and farmsteads such a technique has long been not unusual Destiny of the less fortunate, it seems, can only hope for themselves, for their ability almost from “scrap” to create a solid mechanical aides, but on extremely simple, but trouble-free agricultural implement is “the gift of deep antiquity”.
Buernomu sport in the USSR has a long and glorious tradition. He was born before the revolution, but was at that time available only to a very narrow circle of rich people and General development have not received. After the great October revolution, the picture changed dramatically: in yacht-clubs came young workers, buernomu sport started to develop there have Been many new models for “ice yacht”, and in the Northern parts of our country where the winter is long and a lot of ponds, Buer began to acquire some economic importance as a reliable means of winter transportation. It is appropriate, for example, recall that beresti of Leningrad, took an active part in the defense of the hero city during the siege of 1941-1943 years.
I think many know the situation: you come home from work – totally exhausted and again, eyes clinging to the instrument on the shelf and the “sticks” hanging on the wall since last year. Automatically then I remember that the season has long been opened and begin a frenzy to finish the plane… eyes, lying on the couch. However, this does not last too long. Comes a real enthusiasm and somewhere there is immeasurable energy. But… for some reason it always occurs exactly at the end of the season. And when more than half of the super-model is ready, a bad weather, the rains, snow and other delights associated with autumn. The plane is just so desirable again “hangs” on the wall. He rarely survives until the next season (or tide mood!), often “killed” by a caring hand of his wife, wipe the dust off it.
What should be the car for summer camp? Some not without reason consider that the creation of autoconstructor mug here is futile, since class time is extremely limited. But this, we think, is wrong: you only need to choose an object to design.
The model with the air screw 2.5 cm grade3 designed and manufactured in a self-similar circle of Penza city station of young technicians. It is inherent excellent ride quality, stability and reliability of running. At the VI all-Union winter competitions, this model has a top speed 171,428 km/h and won first place.
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.
