Design

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.

“Eureka” is the Dinghy to the simplified construction, designed for home fabrication technology. The hull of the Dinghy — wooden, lightweight, with the lining membrane type. It consists of three bead frames, keel and four stringers. Midel-frame — reinforced, as it mounted mast and additional parts. The mast of the dural tube or wooden, swivel. The sail is a Latin, with a mainsail area of about 3.2 m2. Additional parts of plywood hinged in the dural tube, sealed at the midship frame.

In the Soviet and foreign scientific and popular journals have repeatedly reported Nicoleta apparatus-ekranoplan, including the Soviet pilot the rescue boat amphibious ESKA-1. This car is Amateur-built successfully last cycle of flight tests, designed by Moscow engineers Gramatzki A., E. Grunin, S. Chernyavskaya, Y. Gorbenko and N. Ivanov. Flight tests were conducted by an engineer A. Gramatzki, and then the pilot Baluev A.. ESKA-1 was exhibited on one of the Central exhibitions NTTM was awarded a bronze medal VDNH USSR, and its creators — signs of the winners of the NTTM.
