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”.
SUPERPOLITIK JUNIORS
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.
Among the difficulties which beset the creators of the homemade mini-tractor (MT) at every step, or three, judging by editorial mail, nesereznaya: the complexity of vehicle development is quite reliable and strong engine, compact transmission and rear axle, whose design is largely determined by the mobility of the machine, and its appearance, and maximum ground clearance…
“Hello, dear editors! Write “M” from 1969. Drawing magazine has fulfilled a number of projects. Pleased with them, that is, on all hundred. Particularly pleased with microtracker Amurchonok, has become my reliable assistant. He will plough the ground, and weeding perform, and hilling plants with it — no problem. And required construction works: load, which should drop the mortar (concrete) is thoroughly kneaded. I would like to equip your microtracker potato. The same as in the photo stitch “M-K” 5’89. If you publish the blueprints, then the fall will have time to do everything. To harvest potatoes to carry on their plot for not using old-fashioned shovels, and a modern, mechanized way.
The proposed model glider created based on ideas… not to be used as a construction material balsa and composite materials. The supporting plane of the apparatus — traditional design. Despite the lack of hard cladding nose part of the wing, consoles have sufficient rigidity on twisting. When the geometric proportions corresponding to the best representatives of this class, the model makes a good start with Leer and reliable planning with winds of up to 7-10 m/s. At high accelerations on consoles is not excluded for arbitrary twist, so it is not recommended to install on the glider towing hook with automatic dynamic start.
