Many of you probably noticed that the wiring of cargo ships in the mouths of rivers, on inland waterways and open sea raids using special vessels with a large inscription on Board the “PILOT”. This is a pilot trial. In accordance with the standard of their share on the botton with a displacement of up to 10 tons, boats with a displacement of 10 — 250 tons and the actual pilot vessels. In Russia are in operation all of the above types of pilot boats.
Readers of “M-K” has long been familiar with the enthusiast a homemade tilling equipment, designer, lover of Nizhny Tagil Grigory Ivanovich ODEGOVA. After all, he managed to develop one of the most effective metalbeat that performance is better than tillers, and motorize and even microstructure. And this despite the fact that the engine olegovskoy of motoliberty — only powertrain of an old “Vyatka”.
The idea is to use the wind power to travel across the icy spaces of the winter Binala I have cherished for a very long time. Even tried to develop a special Buer, tested his design on models. But the final decision was made when I heard that a similar trip was made in 1982, the band of the Moscow Berestov. We have set ourselves a task: to pass a frozen lake, with its southern tip to the North. A preliminary analysis of the conditions of the voyage showed that the ice, along with open spaces on the lake meet and snowy places. In addition, the ice surface is not always perfectly smooth, although there are literally mirror sites. And another thing: often the ice is broken stenovymi with cracks, paths with high piles of ice — hummocks.
Attempts to use the competitions to openly simplified educational technology in the classroom cord aerobatic models, naturally, can not give good results even when well developed the skills of the pilot. But, oddly enough, is equally deplorable results brings and following the design methods of adult artists. The explanation is simple: the boys, even a few years dedicated solely to piloting, may not be so rich operating experience of the championship-tion equipment and motors which are required when you use a specially designed professional “pilotage”. But the latter, as a rule, is, in fact, the epitome of achievement in this sport классе1 And any drawings of modern models-“Champions” (which become the base for the construction of even the Junior vehicles with engines of large cubic capacity) absolutely exclude any discounts on “ignorance” or “inability”.
Among heartfelt-sincere songs many, apparently, about the memorable autumn, when the “yellow leaves over a city are turned, the quiet rustle under our feet lie…”. Really romantic, beautiful. But… Fallen leaves should be removed. In itself, the lesson is simple but laborious. To alleviate monotonous, meter by meter sweeps of areas with a rake called an interesting development innovators and inventors. About the most successful technical solutions “modelist-Konstruktor” has already told his readers (for example, No. 9’93). Regular publication of thematic collections based on the materials of the Polish magazine “Technical noviny”.
In the last ten years, model Aeronautics-members syut G. Votki claim with the same success at the national competitions held by the Ministry of education, repeatedly winning prizes. Particularly well the boys compete in classes rezinomotornaya and timer models, where every year they become Champions of Russia. A large proportion of the success belongs to an unusual school design winged vehicles, which were developed in the aeromodelling circle suit.
Before you start the story about our new model of class RM-2, we want to go back a little and to remember with gratitude the publication in “M-K” № 5 for the year 1991, which was the first time in the practice of automodelisme describes the main design principles rezinomotornaya. It should be noted that many of the points of the article for us was, if not a revelation, then at least unexpected. This is especially true of the exploitation of the rubber motor harness, a choice of parameters of the chassis and check the nature of the motion models in the boost areas.
Cultivation, furrows, weeding between the rows, earthing up of the plants… For these and other works is a lot of mechanisms and machines. Often quite complex, scarce and expensive. Where plot sizes are small and the soil light, many prefer to settle for a commercially available hand-cultivator-Hiller ROC-35A. And here are a couple or alone, characteristic for the latter case, the method “one step forward, half step back”: moving a considerable shock, but with a small (5-10 cm) back.
The proposed microart class DX-02 is built using the experience of Czech and American athletes, as well as materials of the journal “modelist-Konstruktor” about sailing armed with a pyramid scheme. Its design allows to realize the advantages of this scheme over the traditional in terms of the competition in this popular youth class. The yacht is easy to manufacture, and build it could even by a constructor of ship models with little experience.
Today we offer air fighters rather unusual material. It to modelers “mediocre” are not only good examples of several design developments that can be used to practice aerial combat, but based on them the basic principles of the calculation and creation of new machines. We hope that the theoretical part of the material will be even more useful than pure information: it will help not only in understanding the strengths and weaknesses of existing models, but also in the design of bizovac new types.
