A snowmobile, also known as a snowmachine (chiefly Alaskan), motor sled (chiefly Canadian), motor sledge, skimobile, snow scooter, or simply a sled is a motorized vehicle designed for winter travel and recreation on snow. Their engines normally drive a continuous track at the rear, while skis at the front provide directional control. The earliest snowmobiles were powered by readily available industrial four-stroke, air-cooled engines. These would quickly be replaced by lighter and more powerful two-stroke gasoline internal combustion engines and since the mid-2000s four-stroke engines had re-entered the market. The challenges of cross-country transportation in the winter led to the invention of an all-terrain vehicle specifically designed for travel across deep snow where other vehicles foundered. , the snowmobile market has been shared between the four large North American makers (Bombardier Recreational Products (BRP), Arctic Cat, Yamaha, and Polaris) and some specialized m ...

Snowmobile Skipping
Snowmobile skipping, snowmobile watercross, snowmobile skimming, water skipping or puddle jumping is a sport and/or exhibition where snowmobile racers Hydroplaning (tires), hydroplane their sleds across lakes or rivers. Basics Snowmobile watercross consists of crossing water while riding a snowmobile, which is possible because snowmobiles have wide tracks for traction and flotation in the snow. If one hits the water at an adequate speed (5 mph per 150 lb or km/h per 100 kg of weight) and keeps the sled's throttle open, the track keeps the snowmobile on the surface of the water without sinking. If the rider backs out of the throttle or the sled bogs or floods out, the sled will sink. A sunk sled is able to be revived by cleaning water out of the carburetor, exhaust, spark plugs, and replacing the fuel. The front of the sled is pitched upwards as riders commonly do in deep mountain powder snow. History The Grantsburg, Wisconsin first annual World Championship Sn ...

Caterpillar Track
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the t ...

Adolphe Kégresse
Adolphe Kégresse (1879, Héricourt, Haute-Saône - 1943) was a French military engineer who invented the half-track and dual clutch transmission. Born at Héricourt, and educated in Montbéliard, he moved in 1905 to Saint Petersburg, Russia to work for the Russian Tsar Nicholas II. To improve the mobility of the imperial car park, he invented the Kégresse track to modify normal motor vehicles into half-tracks. He was also a personal chauffeur of Tsar Nicholas II and the Head of the Mechanical Department of the Russian Imperial Garage at Tsarskoye Selo. The Aide-de-camp to Tsar Nicholas II, Prince Orlov wrote in a letter to the Tsar's Minister of the Court on May 15, 1914: "... I consider Kégresse an irreplaceable worker and I am afraid his leaving will be a great loss for the garage. Your Highness knows, of course, how much His Majesty appreciates Kégresse." In 1908, the architect Lipsky VA designed a second two-storeyed Art Nouveau building for the Russian Imperia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Winter War
The Winter War was a war between the Soviet Union and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. Despite superior military strength, especially in tanks and aircraft, the Soviet Union suffered severe losses and initially made little headway. The League of Nations deemed the attack illegal and expelled the Soviet Union from its organization. The Soviets made several demands, including that Finland cede substantial border territories in exchange for land elsewhere, claiming security reasonsprimarily the protection of Leningrad, from the Finnish border. When Finland refused, the Soviets invaded. Most sources conclude that the Soviet Union had intended to conquer all of Finland, and cite the establishment of the Finnish Democratic Republic, puppet Finnish Communist government and the Molotov–Ribbentrop Pact' ...

Red Army
The Workers' and Peasants' Red Army, often shortened to the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army (which embodied the main component of the Soviet Armed Forces alongside the Soviet Navy) was renamed the "Soviet Army". Following the dissolution of the Soviet Union it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army. The Red Army provided the largest land warfare, ground force in the Allies of World War II, Allied victory in the European theatre of World War II, and its Soviet invasion of Manchuria, invasion of Manchuria assisted the un ...

Igor Sikorsky
Igor Ivanovich Sikorsky, (25 May 1889 – 26 October 1972) was a Russian-American aviation pioneer in both helicopters and fixed-wing aircraft. His first success came with the Sikorsky S-2, the second aircraft of his design and construction. His fifth airplane, the Sikorsky S-5, S-5, won him national recognition and Fédération Aéronautique Internationale, F.A.I. pilot's license number 64. His Sikorsky S-6, S-6-A received the highest award at the 1912 Moscow Aviation Exhibition, and in the fall of that year the aircraft won first prize for its young designer, builder and pilot in the military competition at Saint Petersburg. In 1913, the Sikorsky-designed Sikorsky Russky Vityaz, ''Russky Vityaz'' (S-21) became the first successful four-engine aircraft to take flight. He also designed and built the Sikorsky Ilya Muromets, ''Ilya Muromets'' (S-22 – S-27) family of four-engine aircraft, an airliner which he redesigned to be the world's first four-engine bomber when World ...
