Tupolev A-3 Aerosledge
The Tupolev A-3 Aerosledge is an all-metal amphibious aerosledge, designed to transport passengers and light freight in remote areas of the Soviet Union. Officially known as the A-3 ''"Hope"'' (''"Nadezhda"'' in Russian), it uses a single pusher propeller mounted behind the enclosed cabin to propel the craft over snow or water.McLeavy, Roy, (1982). "Jane's Surface Skimmers", London, England: Jane's Publishing Company Limited, pp 65–67. History Year-round transportation of mail, passengers, and light freight has always been a problem in remote areas of Siberia and Eastern Europe. Many communities are surrounded by deep snow, hummock ice, marshes that remain unfrozen, and natural waterways choked by weeds. The constantly changing conditions faced by these communities required the development of a vehicle capable of traveling over a widely varied surface at high speeds in order to deliver mail and supplies, as well to transport passengers, and provide emergency medical relief and ...

Snowmobiles
A snowmobile, also known as a Ski-Doo, snowmachine, sled, motor sled, motor sledge, skimobile, or snow scooter, is a motorized vehicle designed for winter travel and recreation on snow. It is designed to be operated on snow and ice and does not require a road or trail, but most are driven on open terrain or trails. Snowmobiling is a sport that many people have taken on as a serious hobby. Older snowmobiles could generally accommodate two people; however, most snowmobiles manufactured since the 1990s have been designed to only accommodate one person. Snowmobiles built with the ability to accommodate two people are referred to as "2-up" snowmobiles or "touring" models and make up an extremely small share of the market. Most snowmobiles do not have any enclosures, except for a windshield, and their engines normally drive a continuous track at the rear. Skis at the front provide directional control. Early snowmobiles used simple rubber tracks, but modern snowmobiles' tracks are usua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Budaörs
Budaörs (; german: Wudersch; hr, Jerša, or ; la, Vicus Teuto) is a town in Pest County, Budapest metropolitan area, Hungary. Location A suburb of Budapest, the town lies among the Buda and Csiki hills and the Tétény plateau in the Budaörs-basin. The dramatic ''Törökugrató'' hill (''Türkensprung'' in German) rises above the town. History The first settlements of the area date from 3500 BC. Excavations near the Hosszúrét creek resulted in findings from the Bronze Age (1900 to 800 BC). Before the Ancient Rome, Romans, the Celtic Eraviscus tribe occupied the area for about 100 years. Several villas have been recovered from the Ancient Rome, Roman times around Kamaraerdő . Little is known of the early history of the settlement after the Hungarian conquest.

Szolnok
Szolnok (; also known by other alternative names) is the county seat of Jász-Nagykun-Szolnok county in central Hungary. A city with county rights, it is located on the banks of the Tisza river, in the heart of the Great Hungarian Plain, which has made it an important cultural and economic crossroads for centuries. Szolnok also has one of Hungary’s best waterpolo teams. Name and etymology Szolnok was named for the first steward of the city, Szaunik or Zounok. The town was first officially mentioned under the name Zounok in 1075. In the following centuries, it was recorded as Zounok, Saunic, Zounuc, and Zawnuch. The variety of spellings likely comes from phonetic discrepancies occurring when Hungarian sounds - originally written in runic Old Hungarian script - were recorded using the Latin alphabet. Another possibility revolves around speculation that the name Szaunik was not a personal name after all, but rather a title relating to the significant salt trade (salt, hu, s ...

KRISTI Snowcat
Kristi snowcats were 1950s/1960s tracked vehicles suitable for snow and other terrain and produced originally in Colorado and then later in Washington. Propeller drive before track drive According to the introduction, contained in the operators manual: "The development of the Kristi snow vehicles began in early 1947 in the form of a very unusual snow plane. This propeller driven vehicle utilized a control by which the operator could tilt the machine from side to side, in effect raising one ski and lowering the other to negotiate up to 45-degree side slopes and permit high-speed turns without skidding. This tilting and edging of skis after the manner of a skier was called "Ski-Action". Since it could do a "Christie" up or down hill, the trade name "Kristi" was adopted." The Kristi snowplane featured a revolutionary change in ski handling concepts. As stated in the manual, the design was inspired by snow skiers who angled their skis to effect a turn (this angling of skis ...

Airboat
An airboat (also known as a planeboat, swamp boat, bayou boat, or fanboat) is a flat-bottomed watercraft propelled by an aircraft-type propeller and powered by either an aircraft or automotive engine. In early aviation history the term ''airboat'' was applied to seaplanes or flying boats, i.e. aircraft capable of taking off and landing on water surfaces. Early airboats were known as "hydroglisseurs" (airboat in French, "water slider"), hydroplanes, hydrofoils, or other names. See e.g. ''Flying'Volume 4(1915-1916) and Cercle du Mononautisme Classiqu (in French). They are commonly used for fishing, bowfishing, hunting, and ecotourism. Airboats are a common means of transportation in marshy and/or shallow areas where a standard inboard or outboard engine with a submerged propeller would be impractical, most notably in the Florida Everglades but also in the Kissimmee and St. Johns rivers, and the Mekong River and Delta, as well as the Louisiana bayous and Mesopotamian Marshes. ...

Aerosani
Aerosani (both singular and plural; russian: aэросани, literally aerosled) is a type of propeller-driven snowmobile, running on skis, used for communications, mail deliveries, medical aid, emergency recovery and border patrolling in northern Russia, as well as for recreation. Aerosani were used by the Soviet Red Army during the Winter War and World War II. The first aerosani may have been built in 1903-05 by Sergei Nezhdanovsky. In 1909–10, young Igor Sikorsky tested a self-designed aerosani, before he built multi-engine airplanes and helicopters. They were very light plywood vehicles on skis, propelled by otherwise-disused vintage aircraft engines and propellers. Military usage Military use of the aerosani goes back to at least the 1910s. During World War I, aerosani were used for reconnaissance, communicating, and light raiding in northern areas. During the 1939–40 Winter War against Finland some were equipped with a machine gun ring mount on the roof. They could ca ...

Svalbard
Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it is about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and . The largest settlement is Longyearbyen. The islands were first used as a base by the whalers who sailed far north in the 17th and 18th centuries, after which they were abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities were established. The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a demilitarized zone. The Norwegian Store Norske and the Russian remain the only mining companies in place. Res ...
