You can put on the car 4, 8… even 16 wheels. However, in the tundra, for example, even this machine will not work and kilometers. And no wonder that whole design teams engaged in the search for new propulsion, which would come to replace the wheel and provided all-weather cargo delivery, hauling of the forest, the work of the search parties… Already established for this purpose samples of tracked vehicles with very broad, almost 1.5 m tracks, snegokatov, hovercrafts.
As described below, the thresher works on the principle of rolling corn cobs in the progressively narrowing gap formed between the cylindrical drum and concave with rubber surfaces. Cob, salinitas between the drum and the cover, rotates around its axis, while it is separated from the grain.
So it is from time immemorial: the harvest of potatoes and before putting it in winter storage, and shortly before spring planting is sort — separated small tubers, which are fed to cattle or processed for starch.
This tractor for almost 20 years, and all these years he not only regularly serves his Creator A. A. Safenano from the village of Alexandrov, the Tambov region, but also constantly improving. A feature of the car is a bucket-loader which is quite rare among self-made designs. This device is good because it optionally can be used as a blade, for example, when clearing snow from roads.
This velocity model of his own design, is designed to perform a figure of course. The model can be made in the traditional method where the frames are assembled with plywood with thickness of 1 mm, a keel from a piece of wood a cross section of 6X10 mm, the stem is made of plywood of 3 mm thickness, stringers — strips of a cross section of 4×4 mm. the Hull is sheathed with millimeter plywood; experienced modelers make it from fiberglass, pre-prepared matrix. To strengthen the hull glued the keel bar, and extra stringers and a bulkhead separating the engine compartment from the compartment with the radio.
Want to offer readers to build an electric scooter. However, this is only an idea, without detailed development. This electrosolar can be made at home, using the components of industrial scooters. Bearing parts can be made of pipe of suitable diameter.
In most circles of technical simulation in our country now, unfortunately, no funds to purchase even the basic necessities, not to mention the purchase of kits for making teaching AIDS and models. Have to adapt, focusing on the use of industrial and domestic waste. But if a relatively simple design can still be built from “junk” materials, equipment remote control much more difficult.
Tourists, fishermen, hunters and fans of water recreation dream to have a comfortable, not heavy, transportable boat. For this purpose, in my opinion, the most suitable rubber inflatable boat.
A train consisting of a locomotive with a tender car, napep-ing tanks and trucks built in the circle of railway modelling road station of young technicians of the North-Caucasian railway. Did his younger students under the guidance of V. M. lositsky..
