CATAMARAN “FISH” UNDER SAIL

CATAMARAN “FISH” UNDER SAIL

In my amateur boatbuilding practice, it turned out that the small two-seater leisure catamaran “Ryba” is far from the first; I built it even later than the large four-seater tourist sea-faring one (also sail-powered). In some aspects, the small boat replicates the large one—for example, the two-hull (or more precisely, two-float) single-masted scheme, the set Read more…

Autogyro DAS-2

The history of creating our autogyro, later named DAS-2M, spans over two decades. The first flight of the DAS autogyro took place in May 1980 in an unpowered version, towed by a “Zhiguli” car.

All-terrain-snowmobile motorized skis "Blizzard"

In the snowmobile “Blizzard,” which I designed based on many developments published in “M-K,” elements of the schemes of classic snowmobiles, “amfitrak,” snowcat, pneumatic sleds, and aero skis have come together, combining almost all known snowmobile mechanisms. However, my vehicle cannot be attributed to any of these groups – it is a combination of a Read more…

ON A BIKE FOR... SKIERS

Attempts to combine a bicycle with skis have been made before. However, the resulting snowcat designs could only be used to ride down hills. Our reader and engineer L. Gurfinsky, along with his friends, managed to construct a simple reciprocating mechanism that transforms the snowcat into a ski-bicycle: now it can be ridden both downhill Read more…

CHERNIHIV PATENTS
