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.
With the creation of the first combat submarines mankind was in the hands of weapons of great destructive power. Not all naval power and did not immediately appreciated its power and the danger that it represented for shipping. However, until that time, until the sub was technically flawed and the weapons are more defensive than offensive, in the organization of any serious opposition to them by surface ships was not necessary. With this task successfully cope with any armed ship. But it did not last long. Improving submarines have left no doubt that soon they will become a serious enemy surface ships.
Should get hold of your domin part with the land and animals type cows, as memorized from childhood tongue Twister “In the yard — grass, grass — wood” begins sometimes to acquire particular urgency and relevance. In fact, it is a mini-program of preparations for the winter. But for the oven heating is necessary in an average of 8-9 cubic meters of firewood. And cut (the size of the furnace) and pinned! At the mere recollection of this back sometimes whining begins. And then there is worries associated with hay…
Treatment of soil with electrofret. Especially for owners of cottages, gardens, gardens (see, for example, “M-K” 3’83, 1Г90). And in conditions when the prices are steadily rising, when the use of tillers (not to mention scarce mini-tractors) sometimes becomes economically feasible, electrophotonic on small plots of land, that is, out of competition. Convenient and relatively inexpensive, besides, equipped with special devices, they not only allow you to loosen the soil, to weed or hoe the plants, But also to successfully complete a number of other necessary household works.
“Mini tractor, description and sketches of which were published in No. 3 of the journal this year, I really liked it. As, apparently, the other readers of the “M-K”, there was a desire to make much-needed in an economy car-wagon. Moreover, because the engine pumps, and Azovskoe the clutch, and main gear from the electric cars available are already available. Constrains only the lack of information about what the suitable mini tractor front axle, frame, support system. I will be glad to read about all this on the pages of your favorite magazine.”
In one of the reports of competitions rocketmodeler I noted an unusual model sports class Ѕ6А famous athlete Nikolay Sergeeva from Belgorod. How many know it, and you know we have more than 30 years, never ceases to amaze his creative imagination. Was no competition, so he brought them his “brand” new. So it was this time.
One of the main sources of environmental pollution is the vehicles. Therefore, constructors have a natural desire to create alternative, environmentally friendly means of transportation, which fully applies and recumbent. As the basis of its development, we adopted the design of the velomobile V. Mazurchak (“modelist-Konstruktor” No. 10 of 1987). But the technical capabilities are not allowed to repeat the machine one to one, we are particular to this and not sought. Besides, from the point of view of “strength scientists”, analog velomobile is, in our opinion, not very successful scheme of loading the important elements: the junction of the front and rear parts of the frame and the axis of the rear wheels, which can cause breakage of parts or assemblies during operation. But I wanted to make the car reliable (and therefore is durable) and thus to meet at least 20 kg of weight. The velomobile was to have such dimensions that enable it to pass under a standard door of the apartment and fit in a regular (not cargo) lift. Well, that was easy to transport and store, wanted to make it more collapsible.
Today we continue the theme begun with the publication of non-traditional polyopia supersonic fighter-interceptor MiG-25, the New development even more unusual in the choice of the prototype for the copy and overall design of the model. Today, it is about the reproduction in miniature of a legendary airplane “Voyager”, made in 1986 by flying non-stop around the globe. I hope that ego of publications will contribute to the revival of some extinct interest to the class “school” sports polycopy. It should again be noted that Voyager, like the MiG-25, only a single instance of a large number of interesting prototypes, giving modelistica up at any level.
