Practice Amateur autocostruzione, including my personal, shows that wagon layout with the use of wheels with tyre size 5X10 (motorized С3А) provides a very convenient and rational design of little micro-car. That is my “Mikrus”. It is stable, holds the road well, speeds up to 90 km/h the engine under the driver seat and the passenger increases the useful volume, makes the body more succinct. The interior is spacious, seats are arranged, which is convenient for overnight stay and rest. One cannot underestimate the capacious trunk: there is, for example, you can install a baby carriage, not looking. In the right corner of the trunk easy to install the battery, and in the bottom of the fuel tank from the car ZAZ-966. Made for the base, they both increase the load on the rear axle, which improves traction of the drive wheels. And convenient access to the engine: the hood folds with the seat, driver and passenger; repairing and explore without leaving the salon. For transportation of bulky goods — TV, washing machine, fridge — enough to move the back seat forward and fold the seatback or delete it. Get a small truck.

The reduction in the header is clear: GK — mower; unit refers to the width of one meter. So, without any complaints, called their machine with electric drive technology from a young city M. Volgograd region. “Our lawn mower, write the students last year at regional competition “Young innovators — the village” won first place, and at the all-Russian rally of student teams in Voronezh — the third”.
The industry has already mastered the production of some basic parts from thermoplastics. This is an interesting and promising method for production of large series, however, for individual products it is of little use — complex technological equipment. But similar results can be achieved by using has long been utilized by modelers epoxy resin in combination with glass and carbon fibre.
I’m a physics teacher and a faithful subscriber of the journal “modelist-Konstruktor”. Write and assemble a binder began while still a student in 1980. Thanks to him I became one of those whom the people called “avid homebrew”. One of my first designs was a mini-tractor “Gerez”, built together with the guys from the circle of technical creativity, which was led by part-time. Mini tractor took first place in the Republican review of technical creativity of pupils. Engine — motorized С3Д installed across; the gearbox from the car GAZ — 51, rear axle — from “UAZ”, shortened. At the mini-tractor 20 gears: 16 forward and 4 backward speed from 1 to 52 km/h. Its own mass of 500 kg can pull the truck with load up to 1200 kg.
The smaller the cubic capacity of the engine performance, the more stringent the requirements for its design, manufacture, Assembly. Speed, cord of 1.5 cm3, which we offer, fine-tuned for many years, takes into account the shortcomings of previous designs and new directions in creating “polutorachasovom”.
This model has for many years successfully “replicated” by the modelers. The secret of its popularity are the simplicity of design and good flight qualities. And despite the immutability of the size of the “serial” model, in various instances were established micro-motors a working volume of from 2.5 to 4 cm3 in the compression and glow options. But the most often used are widely known for KMD-2,5 and equipped with a propeller diameter 220×120 mm Length of cord, generally used for runs close to the standard value of -16 meters. For the manufacture of parts of the model mainly applies to non-deficient materials.
The unusual technique of grafting of trees was proposed by I. V. Michurin, and in the book N.Verzilina “Travel with house plants” describes this original method of obtaining cuttings from living branches directly on the tree. He was “surrounded” branch vessel with water and gave them the roots of the old branches of the pear and Apple trees, cuttings from which the ordinary by not okorenyayutsya. Most clearly such an experience to spend with oleander: its cuttings are particularly well give the roots in water (about a month).
We named our potato secobarbitol for two main working bodies. It is designed for tuber CA educational experienced and backyards, orchards. Therefore, as the actuator used is an electric motor, although the car, of course, possible to set m to the internal combustion engine of suitable power.
It is no exaggeration to say that the main airframe-the autogyro is the rotor. From the correctness of the profile, from weight, precision, alignment and strength depend on the performance of the gyro. However, non-motorized vehicle on tow behind the car rises only 20 – 30 m. But the flight at this altitude requires mandatory compliance with all previously stated conditions.
