Vezdekhod
The ''Vezdekhod'' (russian: Вездеход) was the first true tank to be developed in the Russian Empire. The word Vezdekhod means "anywhere goer" and in modern Russian means "all-terrain vehicle". The initial project was indeed an ATV. It did not however progress further than a pre-production model, due to problems in the design. The second design, which can be described as tank was submitted to the military only after the news broke about Western tanks and the government started negotiating purchases of them in 1917. Design In August 1914, a 23-year-old Russian aircraft designer Aleksandr Porokhovschikov (Rus: Александр Пороховщиков), based in Riga (now in Latvia), offered to build a vehicle with cross-country capability. The working drawings and estimate were finished by January 1915, and on January 13 approval was given to proceed with construction, the project being supervised by Colonel Poklevskij-Kozello. The Vezdekhod had a welded frame which ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aleksandr Porokhovschikov
Aleksandr Aleksandrovich Porokhovschikov () (1892 – July 27, 1941) was a Russian and Soviet military engineer, tank and aircraft inventor from Saint Petersburg, known mostly for the development of Vezdekhod, the world's first tank (resembling the modern tankette) in 1914–1915. means 'he who goes anywhere' or 'all-terrain vehicle'. Vezdekhod was also the first caterpillar amphibious all-terrain vehicle. Subsequently, Porokhovschikov added wheels to his tank for steering, making it also the first tank design to combine caterpillar and wheel forms of movement. However, the steering was ineffectual and his design rejected. As a student, he designed his first aircraft in 1909. Later in 1911, he established a workshop that manufactured simple biplanes. His personal first flight took place at the Zolitude airstrip on the outskirts of Riga. In 1914, he constructed the world's first twin-tail aircraft. The second version of the plane, named Bi-Kok, had another invention – ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large- caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehi ...

Russian Empire
The Russian Empire was an empire and the final period of the Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, religious, and economic diversity. From the 10th–17th centuries, the land ...

All-terrain Vehicle
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike, or simply a quad, as defined by the American National Standards Institute (ANSI); is a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street-legal within most states, territories and provinces of Australia, the United States or Canada. By the current ANSI definition, ATVs are intended for use by a single operator, although some companies have developed ATVs intended for use by the operator and one passenger. These ATVs are referred to as tandem ATVs. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six-wheel mod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caterpillar Track
Continuous track is 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 tires 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 tracks provide good tra ...

Verst
A verst (russian: верста, ) is an obsolete Russian unit of length defined as 500 sazhen. This makes a verst equal to . Plurals and variants In the English language, ''verst'' is singular with the normal plural ''versts''. In Russian, the nominative singular is , but the form usually used with numbers is the genitive plural – 10 verst, 25 verst, etc. – whence the English form. A (russian: межевая верста, literally 'border verst') is twice as long as a verst. "The verst of the 17th century was 700 sazhens or 1.49 km as against the 500 sazhens or 1.067 km it became at the time of Peter the Great." Finnish ''virsta'' In Finland, a was originally 1,068.84 m according to the Swedish standard, but the Russian verst of 1,066.8 m replaced it after the province was annexed to the Russian Empire in 1809. A was originally 600 (fathoms, 1.781 m), but was then changed to 500 , since the Russian was longer, 2.134 m. A Finnish was defined as of a , the F ...
