It so happened that almost all the children’s toys with a muscular drive — pedal cars, maps, bikes — designed for use in main leg muscles. And almost none of these machines work the muscles of the hands. It is in vain, since the movements resembling, for example, rowing, at the same time would be included the muscles of the arms, shoulders and back. Such actions also contributed to active pulmonary ventilation. All this prompted me to design and fabricate for my son “Roller”-muskurahat with manual transmission.
“ROLLER” BABY MUSKURAHAT
Since 1987, entered into force new “Rules for flying sports in the USSR”. Changed and technical requirements for model rockets. So, in the category B4 (model raketoplana) one of them says: “In the case of models with a flexible wing of the planning part should be more than 50% of the starting mass of the model”. As practice shows, the innovation did not deter the athletes from the construction of miniature gliders, forced to look for new ways of their technical improvement. In our opinion, taking into account the new requirements are a very promising model with Delta wing, designed by athletes from the Moscow city Ramenskoye A. Levin and I. Prikhodko.
The work of our circle of technical creativity at the Polytechnic of light industry does the city have repeatedly told on the pages of “M-K.” At the last such publication number 2 for the year 1989 drew attention to the gas company from the village of Urengoy and Tyumen region appealed to us to develop and manufacture universal all-terrain vehicle. They needed a reliable and easy-to-use machine, with its high traffic, quite comfortable conditions for the members of its crew, as well as buoyancy.
“It’s been fifty years since I work as the head of the aeromodelling circle in syut. Now faced With great difficulties: no aeromodelling materials; if the sets and be available, by type of disgusting quality, and made models don’t fly. Students were little interested in the sport. Beginners have the patience just at the beginning of the construction of a complex model…”
With the magazine “modelist-Konstruktor” I’ve known since high school, often picked up from the magazine interesting ideas, implemented them. Over time, accumulated their own experience, appeared and their development. One of them I want to offer to the readers of “M-K”.
After exit 2 “M-K” for the year 1991, we managed to get acquainted with information materials on the development of the self-similar class E5 in the international arena. Of course, immediately had the desire to compare how close the world level the main provisions of the article “Replikar in model design”, raises issues of design of new car engineering. It turned out that, despite the lack of rich experience of the competition which managed to purchase some foreign athletes, we are much ahead of the time not in the results entered in the results tables, and design techniques to achieve the same goal. This is evidenced by our publications about the car with a direct drive for the last three years. And the creative search for perfection appear to be much more important than blind numbers number of points and points. After all, as they say, to correctly determine the direction of the path is almost pass it. More a matter of technique. Mentioned in the beginning of the article, in fact, is part of or the logical beginning of the proposed material.
Dried fruit in different ways. Most of all — air solar method, have, in addition to the obvious advantages (simplicity, accessibility, etc.), the well-known disadvantages.
“All further race pointless… Too unequal forces!” No, dear reader, it’s not about sports. It is sad the thoughts that must have visited any is not too eminent athlete, trying to somehow keep up with the development of technology in the classes of RC racing action. No doubt, improvement of micro cars, new findings and new design ideas have transformed modern “shells” in the samples extremely complicated and most interesting decisions in sports modeling. But as attractive as such technical progress he, unfortunately, has its downside… And, having, may be much more important than continually improving the results of races, — a sharp decline in the availability radioklass. Will not talk about the problems of domestic equipment and supply good motors.
The editors constantly receive letters asking to tell about wind engines. In this publication we offer to your attention the device, published in the journal “Earmaster”.
Overripe, “non-standard” fruits of the ground… a zealous owner and they go in the case: recycled natural fruit juices. It turns out a valuable product shelf, which in vitamins, biologically active substances has no equal.
