Design

“Shortly before the New year left to drink” — whether in jest, whether seriously says on the website www.snowmobile.ru acting under the nickname (alias) Canosa Alexander Zaozerskaya from the city of Totma in the Vologda region. During a multi-day holidays came across the magazine “modelist-Konstruktor” No. 11 for 1991. It was the publication of a homemade crawler snowmobile “Idea-2”. Also decided to try to build a “snezhik”, good experience of working with iron were for his workshop all woodworking machines made with their own hands.

Well known to our guys managed sledge “Chuk and GEK” called snegokat because it is meant for use only on the slopes of the snow hills. Rapidly — only the wind whistles! — rushing snow-cats down on their three skis. Front controlled, allows you to change direction to avoid obstacles. But as soon as the slope of the end — sled, Proskuriv some more inertia, will stop: on level ground they will not leave. Then on the old proverb: love to ride — love and sleigh to haul! The rope and the slide. But what is it? The distance seemed “Chuk and GEK”, which, having fallen down with the same speed continues to race on a flat snow field. Here the rider was a teenager deploys a cool scooter, and surprisingly others behind him opened hinged to the frame a motor and caterpillar. This is already a snowmobile. And it was built Moskvich Yu. Tereschenko.

Is it possible nowadays to build your own plane? Tver aircraft enthusiasts Eugene Ignatiev, Yuri Gulak and Alexander Abramov answered this question in the affirmative, creating a winged single machine, later named “Argo-02”. The plane was successful: successfully flew on all-Union competitions, was the first winner of regional review-competition of Amateur aircraft in Yaroslavl. The secret to increased popularity of “Argo” Amateur aviators not the designer or the technological refinements of designers, but rather – their traditionalism. The designers managed to achieve a successful combination of waste over many decades of design methods of wooden cars of the 1920-ies and 1930-ies and modern aerodynamic calculations of aircraft of this class. This is perhaps one of the main advantages of the aircraft: its production does not require advanced plastics and composites, rental of high-strength metals and synthetic fabric with the pine timber, some plywood, fabric and enamel.

Unlike analog, in the boat “Victoria” from St. Petersburg to create an air cushion and propulsive forces (thrust) uses an air screw. This allows the machine to move using both static and dynamic air cushion. The transition from mode to mode is performed by changing speeds.

Recalling the history of the snowmobile, realized how long ago began my fascination with construction equipment. Even in his youth (and now I’m already retired) received the specialty of a locksmith and mastered on his own welding business, other specialty Metalworkers. But knowledge of design, to tell the truth, “boast” could not, and to learn there was no place. Built on a whim any “grindaholik” on wheels and tracks went on them and on the road and in the snow, but neither the reliability nor beauty.

This double, the saloon car is undergoing testing. Its main units and components taken from production cars and motorcycles: engine power systems and equipment, as well as wheels from scooter “Tourist”; dampers front and rear suspensions from a motorcycle “Java”; a steering mechanism from “Zaporozhets”; rear brake of the scooter “Electron”.

Wheeled ATVs (all terrain vehicle jokingly called the homebrew “karakachani” or “Rovers”) on low-pressure tires (often referred to as the “Pneumatics”) is a very popular car among designers and enthusiasts. However, the high complexity of manufacturing the wheels, and most importantly — the low reliability of their tires (usually made of cameras wheeled tractors) are often cool creativity of the craftsmen. Meanwhile, a tyre for wheels of such a vehicle can be made of the right tire (diagonal fiber cord, not torn and not quite “bald”) from the wheels of a truck or wheeled tractor.

The Internet has no boundaries and it brings people together. Especially like-minded people. On the website www.minitraktor.Ork.ru user under the name сеnteur from Lithuania is presenting its all-wheel drive mini-tractor with “broken” frame, which has been in operation for twenty years. The engine it — UD-2M. Gear shift — from a motorcycle “Dnepr” and 2-speed gearbox with neutral position — from the old blower to provide mini tractor with eight speeds forward and two back from 1 km/h to 17 km/h.
