On the shelves of sports stores you can often see elegant double sledge for skiing the mountains, called “Chuk and GEK”. The sleds solidly constructed, brightly colored, very attractive in appearance, but… do not use special demand. We do not undertake to judge how good these sleds, what their shop offers, but after the installation of vasodilates D-5 and they, undoubtedly, will be a very interesting self-propelled machine (Fig. 1). Such a construction was offered by a famous Leningrad artist — N. Abramov. In our opinion, the use of sledge “Chuk and GEK” as a basis for creating various children’s trails in machine — sensible initiative. It should be noted that the possibility of their “motorization” is not limited to the offer, which did N. Abramov: in addition to wheel with spikes, can be applied to the screw or the propeller (in the latter case, it will microaerobic). Finally, why not try it instead of the internal combustion engine to set the motor power cable or contact wire?
“CHUK AND GEK” — SNOWMOBILE
Has long been a regular reader and subscriber of the journal “modelist-Konstruktor”. I want to share one interesting result of technical creativity. Sometimes people ask for a drawing apparatus, a photo of which is posted in social networks is decided and for this reason also more to say about it.
If the village is unthinkable without the tens and hundreds of motorcycles, mopeds and bicycles, in the Northern part of the country, where winter lasts nine months of the year, the role of these public vehicles is increasingly performed motonarty. Without waiting for the industry will be able to meet the needs of northerners, many lovers of the snowmobile technicians design and make your metal samples, sometimes not inferior to industrial.
The first development, which we publish, is a universal glider of class “Standard”, called “pennant-4”. Characteristics, it is approaching to widespread machine “Brazil”, but has a number of original nodes, that facilitate and accelerate Assembly and disassembly. The device has been extensively tested in various flight conditions. His flight main advantages: the minimum gliding angle, extended speed range, the ability to execute turns of small radius on all speed range, softness, and ease of management.
F. Slavin from the village Malesina Kurgan region gathered his hands, using the components and mechanisms of various scrapped or abandoned motor equipment.
Usually when we in the club EN-route modeling at the Tushino syt in the beginning of the school year come the newbies, they are already at the first lesson confides that they want to choose for your first model as a prototype? nail last season Ferrari, the unusual six-wheeled “McLaren” or the unthinkable, PA elegance “Carrera” GT class.
Dream master the air ocean has long been concerned with humanity. This is reflected in the legends of antiquity, and the works of scientists of antiquity. The mythological wings of Icarus were made of feathers bonded by wax. Leonardo da Vinci, developing a frame structure of the wings, hoped to move without hands, and stronger leg muscles. But the subdued air element was with… stationary wings. Flapping flight is still not revealed all its secrets.
In the late winter of 1974, on the snowy fields near airport “Domodedovo” there was an unusual car, like the egg of a magical bird, the ROC, or a giant cocoon. Leaving behind clouds of snow dust it with remarkable speed glided across the plain and easily overcome the pretty steep climbs. Maneuverability it aroused universal surprise: a complete course “cocoon” was unfolding just in one place!
Despite all the difficulties of the post-Soviet time, the interest of our young citizens for the modeling are gone, and the ranks of the students, is passionate about making the existing car, ship and plane models with the subsequent participation in sports competitions, are constantly replenished in the circles of technical creativity.
Many professions small all-purpose Ka-26 in he became a forest firefighter. A simple device for extinguishing fires developed at the Leningrad scientific research Institute of forestry. It is a cable device with an outboard tank for collecting water from nearby ponds in flight.
