The prototype model has served as a snowmobile amphibian created in 60-ies a group of young professionals under the leadership of the Soviet aircraft designer A. N. Tupolev. This car attracts the severity of the contours (see “M-K” No. 11 of 1978), do not break any complex suspension system of the ski or tubular enclosure of the propeller. And this is a significant advantage Because each protruding element design increases the aerodynamic resistance. It is better to have a bulky, but streamlined body than compressed to the limit, but with the “stork” legs of the undercarriage. In addition, the housing of such a model creates the effect of aerodynamic unloading, manifested even at low speed. Amphibians have relatively small diameter propeller.
THE AMPHIBIAN ON THE ICE TRACK
What do you notice? They again begin the dog more likely to catch the eye in the yards, on the streets of cities and towns, rural roads — nimble and fast two-wheeled machine with silver spokes. One time, at least in large cities — bikes were everywhere and, it seemed, irrevocably supplanted by multiplying by leaps and bounds with cars. Played a role and decreasing size of modern apartments. But the architects revised the plan, added to the rooms, balconies and loggias, and the designers created a folding bikes — and as a result today we can talk about the revival of popularity of this individual mode of transport.
Since 1983, the Federation of auto modeling sport of the USSR introduced the class E-2. It includes the simplest kordovye model cars with electric motor supplied from the outside! about current source. A new class immediately attracted the attention of young athletes. Simplicity of design, availability of materials and engines, the possibility of competition in every gym, even the school, equal conditions for all invaluable advantages, especially from the standpoint of the development of mass automodelisme. Because machines of this class no matter what the weather outside the Windows, in the village or in the city is a circle of aviamodelirovaniya.
To fill the wheelbarrow with sand, grain or leaves, it is not necessary to take in hands a shovel. Put it on… “scoop”. It is made from plywood, the bottom and sides are fastened dural corners, and the front rivet is a metal “toe”. Fixed design on the body with the latches 3 (window latches) and axis 4. During transportation the “scoop” is placed on the bar-stop.
Usually wings models air combat and cord upholstered Mylar film. Stick it to the frame using BF-2, and the joints are heated with a soldering iron with a special nishikoi. In the Studio or at home it is not difficult. Plugged in the soldering iron to the mains, and after a few minutes the sting is heated to the desired temperature. And how to reheat it on the track during the competition? After all cases when the soldering iron is necessary, abound: a bad fit of the model, accidental damage to skin, peeling off the Mylar film…
Fiberglass and epoxy… once they carried out a coup in Sioux douceline, giving the possibility to applied to the wall of the housing of any lines for any of the models. Indeed, this process is much easier and more productive than obtaining a housing by other methods. But the production of ingots… Make it no easier than the case-“dyblenko”, and the effectiveness of the method of veclachi high only when one blank is used for forming multiple shells.
The original self-similar route, combining elements of technical creativity, sports competitions and physical training, developed a young technology of the German Democratic Republic. Its main distinguishing features — the use of motorcycles instead of a car, replacing the grooves under current-carrying copper bus and rail and, finally, the supply of power from generators installed on the bicycles.For the manufacture of the route will need chipboard or whether-ists of plywood with a thickness of 8-10 mm In accordance with the selected configuration of the “racetrack” and the dimensions of the allocated space cut strips (straight and curved) width of about 300 mm and wire them. The surface of “road” paintings it is best to paste over glass or sandpaper.
Many attract-models tracked vehicles. However, their reproduction is more difficult when it comes to making tracks. Offer the readers of “M-K” I have developed a method of manufacturing such a mover… from the tree. This caterpillar doesn’t have many joints: it consists of tracks, strung on two closed in a ring of nylon fishing line. You first need to glue a wooden profile, which is the cross-section shown in the figure. To “that will require thin strips of plywood and rails of oak or beech, its assembling is held with epoxy glue. Into the grooves better, lay a nylon fishing line — then they will not be filled with adhesive, and after curing 1его thread is easy to remove from the workpiece.
There many important components and parts to trace in the box? Yes, almost everything — so I will answer any, even the young athlete. But surely he’s really isolated from all the other current collector. It is from that little detail most of all depend on the reliability and stability of the micro-car, only on the most difficult parts of the route, and therefore, a high result.
Sectional block method of construction of the larger vessels have proven their effectiveness. It will be useful to modelers. Normally, the body size wikiepedia on the disc, is assembled from wooden slats, is made of metal, is stamped on the matrix. All these ways are good, if not one “but”… Young engineers who are building the model in ways not acquainted with the theoretical drawing of the hull. This also eliminates the collective creativity of students.
