Now, when the time for establishment of school of a subclass of car “E”, in most circles, the problem of designing and building simple micromachines no longer exists. Thanks to the experience gained with it without struggling and novices. However, all this is legitimate when it comes to simplified likes, not tied to specific vehicles, and even the choice of the optimum scheme of the chassis models of any type and class. When the boys, having studied the basics of avtomobilestroenie, go to E-polyopia in front of them immediately raises a number of questions. And no wonder — the level design here on the head above.
A SECOND YOUTH OF A RARITY
Unusual “Junior; model class г2А. the description and drawings which were published in “M-K” № 10, 1993, said a surprising impact on the foundations of our reasoning krukowski theorists. Disputes regarding this model were many, and in the end the boys to vychisleniya truth even built exaggerated flying “test layout”, which was legalized in their brain is given in the publication of the First display after “wow guys seems to have decided to take up the manufacture of good oblagorozhenny machine kapatiran engine. But then, it seems, even to his own surprise, he bowed to the idea to develop another idea, which ended the above-mentioned article, In the end we managed to implement an interesting high-speed model-a duck with it and also with the design and g are susceptible of experimental techniques we want to introduce followers aeromodelling class F2А. Perhaps it will help to create not only a “Junior” but also the current championship, very promising “duck”.
The magazine “M-K” in the last few years has published a number of interesting patterns with rubber motor, with an unusual decision nodes, and technological methods of their creation. Let “garbage weed” from their schemes, to design, we think, a very good and promising machine of the class B1, which combines not only good flight and operational characteristics, but also the manufacturability at a maximum nedvizimosti raw materials.
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.
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”.
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.
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.
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.
