“Ancestor” of this machine, lawn mower GK-1 was built by students in St Michael’s training and production plant in 1978. About it has told the head of young technicians — lecturer of the criminal procedure code V. I. Popov (see “M-K” № 6, 1981). However, the possibility that the mower was still insufficient: the width was only 1 m and the actuator will bind the mechanism to a power source and thereby limiting its autonomy. This was the reason for making a new variant with high performance. The novelty was successful. Among the exhibits of the III all-Russian rally labor unions of students in urban schools, held in Rostov-on-don, she invariably attracted attention and was awarded by our magazine (see “M-K” N° 1, 1985). By the way, after this publication in the code of criminal procedure, Michael began to come from all over the country a letter asking them to send drawings of the mower. To answer each individually the authors, of course, was not. Today we provide the pages of the magazine mentor young designers of this machine.

It is not similar to any of the existing transfer machines. Outside no wheels, caterpillars — not at all friction parts, gland seals. Only the bottom constituting an elastic pad, flexible: can be bent, forming a traveling wave. Wholehog designed and built by the Lipetsk engineer Yu. V. by Arpinum. Projection wanaheda given at different phases of movement. The kinematics of this machine are not very easy to understand. At first glance it seems that, even raised ka solid surface, it does not budge, no matter how much I ran her to the bottom of the wave. In fact it is not.
Today our story is about the original high-speed input developed in the circle of children’s club “Iskatel”. Designed for the most advanced scheme, it contains a number of technical innovations that may be of interest to experienced athletes. Cord hydroplane class A1 favorably known development the lack of scarce or toxic in the materials — balsa, glass and carbon fiber reinforced plastics, which gives the possibility of recommending the model for the building even in the school clubs shipmodelbuilding. The use of standard domestic engine CSTOM KRAS ensures the implementation of fitness standards on the level of a first level up to the candidate master of sports.
On the mechanisms used to its movement due to inertia of the rotating imbalances of the journal “modelist-Konstruktor” wrote more than once (see number 5 and 12 for 1975, No. 6 1976, No. 3, 1978). The publication aroused great interest among readers, so we return to this topic. The amazing ability of nutricola, or inertsioidov, as they are called — to move without using wheels, tracks or air screw — continues to captivate enthusiasts-inventors. And although the effectiveness of this type of propulsion is not yet well-known competitor, perhaps one of the most perfect models of nutriton will be a prototype of the future transport. And while we offer to your attention another scheme inertsioidov mover. Its author — kas reader from the city of Ryazan Alexander Mikhailov.
On private land, perhaps only a decorative grass — raygrass — tracking, scattering the seeds. The vast majority of annual flowers and vegetables planted in rows: so the plants are easier to handle and feed. But since seeds are small, often the shoots are too dense. You have to spend a lot of time pulling, away, by the way, is harmless to the root system.
More widely used today snowmobile technology. Industry and Amateur craftsmen create a wide variety of vehicles specially designed for use in the winter. For now the spring comes, and the powerful “Buran” is sent to the Parking lot to the garage to wait for the next season, and its owner is transplanted to the other “horse”, most often the motorcycle. But would it be useful to have two almost identical vehicles differing only in chassis? Can we make a universal motorcycle-snowmobile? This task is successfully solved by our readers from the city of Votkinsk Udmurt ASSR A. Drummers.
Now more and more can be found on the streets guys, balancing on the rolling boards. They are not only confident of their own on descents: even the most adept going up a hill, easily doing complicated pirouettes ka slalom tracks, sometimes demonstrate a downright acrobatic stunts. Popular among young people, the shell is called a skateboard, occupation — rolling. Movement standing on a roller Board are very similar to those performed by the skier passing through the gates on the descent, or the surfer, especially when you tack. Indeed, the skateboard was created as a simulator for the skier, but soon became widespread as an independent apparatus. Rolling becomes a sport: many fans began to unite in section at stadiums, various sports clubs. According to the head of laboratory all-Union scientific research Institute of physical culture, doctor of medical Sciences V. V. Matte, skateboarding develops agility, reaction speed, coordination of movements.
Getting the design of this machine, I proceeded above all from the conditions of its future work. The soil in our area is mostly heavy loam, stones… and surface plots are far from perfectly smooth. In short, the operation was not easy. This fact determined the choice of the main parameters of the mechanism.
Model of champion of the USSR in 1986 in the class S4B V. Lunichkina is the result of work on improvement of the gliders with a flexible slat. Speaking with such devices, the Kazakh sportsman became the winner of many competitions.
“School” model class F2D — further development of the schematic published in “M-K” № 7, 1986 in the article “Record holder… simplicity.” Indigenous improvements of the characteristics of the new device was able to achieve, preserve the unique simplicity of the power unit (which rivals and assigned to our bouzoukis the name “schematic”). This primarily refers to the stability of the start and the behavior of the model in the maneuver on the windward side of the flight hemisphere.
