Snowplane — sled self-propelled, equipped with an internal combustion engine with a pusher propeller (propeller). This vehicle is intended for movement on snow and ice. The speed of the snowplane, depending on engine power from 25 to 140 km/h. Snowplanes have a chassis consisting of 3 or 4 skis.

1903 was the date of birth of the snowplanes, which later became very widespread. And in 1905 the magazine "Aeronaut", called them "sleds with air screw for movement on snow," by design — engineer Sergey Sergeevich Nezhdanovsky.


The first model was a light sledge on which was mounted an internal combustion engine with aerodynamic propulsion — propeller. Already in 1907 at the Moscow factory "Dux" was built and tested "ski car" Y. A. Meller, designed in collaboration with the engineer A. D. Dokuchaeva. A year later this machine was called the snowplane.

The design of the snowplane "Dux" consisted of light wooden sleds with runners from conventional cross-country skiing. At the front of the sled had the steering wheel, which, with the forward ridge could change the direction of their movement. At the rear of the sled was located petrol engine air cooling "Dion Bouton" power of 3.5 HP Through two pulleys and belt transmit a rotation of the motor shaft is transferred to the shaft of a two-bladed screw. The present sled speeds up to 16 km/h.

In January 1910 experienced a snowplane of his own design, future famous aircraft designer I. I. Sikorsky.

To compare the characteristics of snowplanes of different designs, evaluating their strengths and weaknesses was conducted in Russia aerosonde runs. The first was organized by the Russian automobile society was held and in February 1911 in Tsarskoye Selo. The results of the run allowed us to speak about the suitability of the snowplane for movement not only along the washboard road, but on loose snow, the Second cycle took place in Moscow in January 1912 was initiated by the Russian society of Aeronautics and the first Russian automobile club.


The emergence of the first mass-produced refers to 1912, when the Russo-Baltic plant began construction of party transport of the sled by order of the war Ministry. By then snowplane machines drew attention abroad: in France, Austria, Germany and other countries. With the outbreak of the First world war, the snowplanes have been used and at the front. Already in the winter of 1914-1915 they were used for reconnaissance, communications and other operational tasks command.

The highest use of snowplanes in the great Patriotic war, especially in the winter campaign of 1942/43, In this period they were first used in large numbers as a means of combat. Practice has shown that the most successful aerosonde parts acted in an open area: to the lake spaces lakes Ladoga, Ilmen and Seliger, frozen rivers, coastal areas and the sea in the Gulf of Finland.

The movement of the snowplane across rugged terrain and forest) road width 4-4. 5 m is difficult, and sometimes impossible. On narrow forest roads with frequent turns, lots of stumps and twigs, as well as on the ground, covered with bushes above 6.5 m, the speed of the snowplane is sharply reduced and frequent breakage of skis and screws.

This is a nice collection of photos. The vehicles by themselves look very "Steampunk" already. I'm liking that"dux" craft.  It's also nice to see some of Sikorsky's early history.
