Design

Small farm equipment — a great helper in the garden, at the farm. Those who have the area roomier, and opportunities to make difficult a bigger car, opt for microfracture the most energy efficient, versatile and easy to use machine. About your variant of compact four-wheel tractor, called the author of “Zubrenok”, says our reader A. E. Parfenov. Once, flipping through a magazine “modelist-Konstruktor”, read about homemade compact tractor Amurchonok. Liked the idea, and I decided to build my machine for plowing and harvesting in the garden, performing various works in the Hayfield, to facilitate other types of heavy physical labor at the farm. I believe that I did it. The tractor turned maneuverable, powerful enough, looks quite nice and reliable — in two years almost constant use in the harsh Siberian climate had not happened no breakage. At the district exhibition “Technical creativity of youth and schoolchildren of Siberia” in the spring of 1983, my “house of the child” received a high rating and was awarded an honorary diploma.

We can say that in the mid 30-ies of the aircraft wing went down from the sky… ice. It was then that ka “ice birds” high — speed snowmobiles — instead of sails began to put aerodynamic wings are very similar to aircraft. But it took another few decades, and airfoil on the ice in the truest sense of the word was on its feet. Moreover, skaters it just became to put on… coat.

Every Sunday the gates are opened to the sports section “Buggy ERMZ”. To the factory yard with the characteristic of motorcycle engines crack go dirt buggy. Today exercise. Guys this day is going to the most and everyone wants to try the forces in front of its closest competition, after all, to drive lucky one who has shown the best result of training and worked hard in the creation and preparation of the machine for the contest. The guys mostly 16-20 years, many of them are passionate about technology with a 3-5 class and have an enviable ingenuity. Sports for them is a favorite form of leisure. But soon they will graduate come to the production, army groups, and the technical knowledge and practical sports skills, fitness, purchased in the sports section, will probably come in handy in life. Practice shows that those who engaged in technical sports, proactive and hardworking in the production, they usually say “Jack of all trades”.

Filled with wind-taut sail… This age-old symbol of romance will not leave anyone indifferent. And there is nothing surprising in the fact that the number of sailing enthusiasts every year increases. Today they are much more than you can take the yacht clubs, so work on creating Amateur sailing ships many have no qualified advice.

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.

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.

Perhaps this design will not leave indifferent any fan of Windsurfing. Still, is it not tempting to make a sailing Board, you can practice your favorite sport almost all year round! But that’s not all. Such a shell can become a kind of winter trainer for learning the basics of sailing.

This two-cylinder engine, which received the name DD-700/40, designed and built the head of the public design Bureau “Aerocam” George Dorfman. The motor turned very good: reliable, relatively simple, easy enough.

The proposed design is the winner of one of the contests of velomobiles in the Lithuanian city of šiauliai.
