In the journal “modelist-Konstruktor” was published an article by a teacher from the city of Severodvinsk Vladimir Arkhipov, dedicated to the manufacture of plastic fine-grained cylindrical gears for motor car, ship and plane models on the example of gear made of polyethylene with the basic settings of m = 0.8 mm and z = 8. Continuing the theme, the author offers the readers a mold similar to the previous one, but with one fundamental difference — it is designed for making small batches of disc gears with the end location of the tooth.

“If we turn the pages of aviation history, you will find that most modern aircraft as heavier than and lighter than air born motorless aircraft were gliders, airships — balloons. Motors came in the process of evolution. About the same we are seeing now in hang gliding: after the glider to a pure glider version began intensive work on its “motorization”. They were conducted in parallel, both Amateurs and serious scientific institutions, aircraft manufacturer. And got results that suggest that in the near future, the trikes will become an independent unit of the aircraft. This is evident, in particular, a recent flight on an ultra-light aircraft across the English channel from London to Paris, in the ways of the early aviation pioneers. At last year’s aviation show in Le Bourget has demonstrated the device “Metadata”, produced in Germany. The machine flew well. No doubt that experiments like performed by S. Belikova, deserve every poderina, first and foremost, the Federation of hang gliding sports of the USSR”.
On the table — a fleet of unusual vehicles “cars”: no wheels or tracks or ski. And yet they move. But their movement is also unusual: both by land and by air. Not accidentally, the creators called their catholicae. These small-scale models has a large future: they open a completely new direction in the evolution of transport. Developed in Kramatorsk inertial-pulse machines, the Committee for inventions and discoveries issued three certificates.
Not so long ago in the journal “modelist-Konstruktor” was about the simplest model of a glider made from a conventional packaging corrugated Board material although not aeromodelling, but it is durable, tough and light. By the way, a square meter of corrugated Board with a thickness of 3 mm has a weight of only 400 g, respectively, the density of this material is only 0.13 g/cm3! Experiments have shown that the durable and lightweight corrugated cardboard is well suited for creating flying models. Needed only in the cutting and processing of corrugated Board to consider some of its features and to use a knife-cutter, literally honed to razor sharpness, otherwise cut lines get ragged.
Before you engage in the construction of microvesicle, I’ve been drawing various versions of its layout, trying on paper for all possible errors and miscalculations, which can only occur in the process. Looking ahead, it should be noted that designing on paper is one thing, fabrication is another. Many of the “roughness” out in the operation of the machine.
MODEL No. 1. This design is a continuation of work on improving the model, which is described in “M-K” (No. 1, 1972). For better aerodynamics it is applied to a fuselage of circular cross-section. The keel has a swivel mechanism to provide a forced descent. The screw diameter is increased to 556 mm, which contributes to the duration of the flight motor and improves the dynamic
Room models of small size. Simple in design and in manufacture. Material for their construction can serve as dry stubble and any weed, its structure is similar to a stalk of wheat. As the adhesive used enamel or plain nail Polish. Of tools enough to have scissors, pliers and a razor blade from a safety razor.
The Rover, shown in the photo, the original was made in a caterpillar form, and then converted into a four-wheel drive wheel, which for many years is in operation. Each of the six wheels, the front pair of which is driven, has an independent suspension. Wheels — tyres low-pressure chambers wheels tractor truck with a longitudinal brace and the transverse belts of the conveyor belt.
Ultralight Dinghy international class “Moth” “the Moth” (Fig. 1, 2) simple in design, convenient in construction and possesses all the essential qualities of sports ships – fast, maneuverable and sensitive to control. All this allows to recommend it as the first sport of sailing to those who wants to achieve in sailing Olympic heights.
