Build model rockets. The first manned flight into space, our compatriot Yuri Gagarin in 1961 was the beginning of a new the directions of technical creativity — rocket-and-space modeling. And from the first steps of this interesting kind of design magazine “modelist-Konstruktor” became its active promoter and popularizer. And loyal to him until now.
In the soul of every boy living Navigator, so any rain brook — is a river, and a large puddle is a sea calling out to let the boats from the simplest of chips or a sheet of paper, to specially planed, and the more such combined, as proposed by the German magazine “Technium” self-propelled model of a boat. Yes, no ordinary boat, but an old, two-pipe, with paddle wheels at the sides. What child would not want to build like this, especially because the design is quite affordable for independent playback.
Wheeled Buer, beach sailing, sand yacht, metromobile… All these terms refer to the same Tina of vehicles using the movement force of the wind. Designs of such “petroholod” — a great many, from year to year are added up — three wheels and four, with Latin sail and with the Bermuda arms, hard planes, reminiscent of an aircraft wing, and even with a horizontally positioned fan-like impeller anemometer.
A simple device developed by members of the self-similar circle of Ufa city Palace of children’s creativity, shoal be useful to many tracks. It makes it very easy to create a miniature race track for sea trials models. We have seen this, having tried it, in fact: “digging,” grooves on a track is accelerated many times over.
No matter how much we have seen this picture every time it will amaze and fascinate with their uniqueness: easy flick of a switch — and just as silently as it stood, the car started and ran, picking up speed. The heart of this design — the electric motor. To it again drawn the attention of automakers and even in connection with energy problems. Do not stand aside from these searches, and Amateur designers, some of their works have been highlighted on the pages of our magazine. Today we introduce the electric car of formula D — baby, built by our reader A. Logvina from the city for his daughter called “Alyonushka”.
Speed kordovye models are very popular among modelers of the USSR. According to the classification of models of the ships they are United in group a-and are divided into four classes: A-1 — speed cord model free design with internal combustion engines working volume of 2.5 cm3, with the propeller; class A-2 — speed cord model free design of the internal combustion engine up to a volume of 5.0 cm3, with the propeller; And-3 — speed control line model free design of the internal combustion engine up to a volume of 10.0 cm3, with the propeller; In-1 — speed cord model free design with internal combustion engines up to 1.5 cm3, with a propeller.
The reduction in the header is clear: GK — mower; unit refers to the width of one meter. So, without any complaints, called their machine with electric drive technology from a young city M. Volgograd region. “Our lawn mower, write the students last year at regional competition “Young innovators — the village” won first place, and at the all-Russian rally of student teams in Voronezh — the third”.
The industry has already mastered the production of some basic parts from thermoplastics. This is an interesting and promising method for production of large series, however, for individual products it is of little use — complex technological equipment. But similar results can be achieved by using has long been utilized by modelers epoxy resin in combination with glass and carbon fibre.
I’m a physics teacher and a faithful subscriber of the journal “modelist-Konstruktor”. Write and assemble a binder began while still a student in 1980. Thanks to him I became one of those whom the people called “avid homebrew”. One of my first designs was a mini-tractor “Gerez”, built together with the guys from the circle of technical creativity, which was led by part-time. Mini tractor took first place in the Republican review of technical creativity of pupils. Engine — motorized С3Д installed across; the gearbox from the car GAZ — 51, rear axle — from “UAZ”, shortened. At the mini-tractor 20 gears: 16 forward and 4 backward speed from 1 to 52 km/h. Its own mass of 500 kg can pull the truck with load up to 1200 kg.
The smaller the cubic capacity of the engine performance, the more stringent the requirements for its design, manufacture, Assembly. Speed, cord of 1.5 cm3, which we offer, fine-tuned for many years, takes into account the shortcomings of previous designs and new directions in creating “polutorachasovom”.
