The ski-traction motor is a specialized snowmobile propulsion consisting (with rare exception) from the separately mounted tracked propulsor (usually from the rear) and one or several skis (usually from the front) providing additional support and maneuvering [1] [2] [3] [4] [5] . It has a low specific pressure, high maneuverability and high speed when driving on snow cover [1] , but it is completely ineffective on other types of surface and is unsuitable for use on them. The most widely used first on snowmobiles (widely used to date [6] ), and later - also on light snowmobiles (motonarts).
The ski-tracked propulsion is structurally similar to the semi-tracked , and the ability to quickly convert the semi-tracked propulsor to the more efficient ski-tracked on snow by fixing special removable skis on wheels (or installing them instead of wheels on the axes of a controlled bridge ) was designed by many semi-tracked all-terrain vehicles .
Nezhdanovsky Ski & Tracked Propulsion
The original propulsion developed by the Soviet inventor S. S. Nezhdanovsky is also referred to as ski-tracked. In its construction, the skis are covered with ribbons of a caterpillar propulsion unit, located inside their size - at the same time, due to a special rare-track device of caterpillars (enveloping the caterpillar, not in contact with it, due to the supporting rollers), as in the traditional track-caterpillar driver with a separate track arrangement and skis, continuing to perform an independent support function. Nezhdanovsky propulsion is even more effective in the snow than traditional ski-tracked, but because of the total complexity and a number of intractable problems associated with the peculiarities of its design, it has not found [5] [7] [8] [9] .
It is noteworthy that such a propulsion unit, which is in itself a ski-tracked vehicle, can be used (instead of a tracked propulsion unit of conventional design) in combination with a ski-tracked propulsion unit with separately placed skis (this option was implemented, in particular, on an experienced BA snowmobile vehicle -64-З ) [5] .
