Kugelpanzer
The ''Kugelpanzer'' ("ball tank") is a one-man armoured vehicle built by Nazi Germany during World War II. The history of the vehicle is practically unknown other than the fact that at least one example was exported to the Empire of Japan and used by the Kwantung Army. The machine remains something of a mystery due to the lack of records and the incompleteness of the sole surviving model. Surviving example Only one example of the ''Kugelpanzer'' still exists today. It was captured by the Red Army in Manchuria and is on display in the collection of German armoured vehicles at the Kubinka Tank Museum in Moscow where it is described simply as "exhibit no. 37". There is no record of it ever having been used in combat. However, another report states that it was captured at the Kummersdorf proving grounds along with the infamous ''Maus'' super-heavy tank. The vehicle was modified after its capture, repainted and its drive removed. In 2000 the original paintwork was restored. Theo ...

Kubinka Tank Museum
The Kubinka Tank Museum (Центральный музей бронетанкового вооружения и техники - Tsentral'nyy Muzey Bronetankovogo Vooruzheniya I Tekhniki -Central Museum of Armored Arms and Technology) is a large military museum in Kubinka, Odintsovsky District, Moscow Oblast, Russia where tanks, armoured fighting vehicles (AFVs) and their relevant information are displayed and showcased. The museum consists of open-air and indoor permanent exhibitions of many famous tanks and armored vehicles from throughout the 20th and 21st centuries (between 1917 and the present day). It also houses and displays many unique, unusual and one-of-a-kind military vehicles of which there are very few remaining examples, such as the German Panzer VIII Maus super-heavy tank, Troyanov's Object 279 Kotin heavy tank, the Karl-Gerät heavy self-propelled artillery, and the Object 120 Su-152 "Taran" tank destroyer, amongst other single or limited-production prototypes f ...

Wunderwaffe
''Wunderwaffe'' () is German word meaning "wonder-weapon" and was a term assigned during World War II by Nazi Germany's propaganda ministry to some revolutionary "superweapons". Most of these weapons however remained prototypes, which either never reached the combat theater, or if they did, were too late or in too insignificant numbers to have a military effect. The V-weapons, which were developed earlier and saw considerable deployment, especially against London and Antwerp, trace back to the same pool of highly inventive armament concepts. Therefore, they are also included here. As the war situation worsened for Germany from 1942, claims about the development of revolutionary new weapons which could turn the tide became an increasingly prominent part of the propaganda directed at Germans by their government. In reality, the advanced weapons under development generally required lengthy periods of design work and testing, and there was no realistic prospect of the German milit ...

Monowheel
A monowheel, or uniwheel, is a one-wheeled single-track vehicle similar to a unicycle. Hand-cranked and pedal-powered monowheels were patented and built in the late 19th century; most built in the 20th and 21st century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles. The world speed record for a motorized monowheel is 98.464 km/h (61.18 mph). Stability Similar to bicycles, monowheels are stable in the direction of travel, but have limited horizontal stability. This is in contrast to unicycles which are unstable in both directions. Monowheels have also been found to have a lower speed required for stability when compared to unicycles. A monowheel remains upright due to gyroscopic effects, but its lack of stability makes it highly dependent on forward momentum and the balance of the rider, who must maintain stability while steering. Over the history of the monow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kummersdorf
Kummersdorf is the name of an estate near Luckenwalde, around 25 km south of Berlin, in the Brandenburg region of Germany. Until 1945 Kummersdorf hosted the weapon office of the German Army which ran a development centre for future weapons as well as an artillery range. Early history In 1871, the Prussian ministry of war decided to move the artillery test range at Tegel to the Kummersdorf Forest. The new range became operational on 15 October 1875 when it was connected with the Royal Prussian Military Railway. In 1880, the first firing experiments took place on the 12 km southeast-northwest firing range. These experiments investigated the effectiveness of various fortifications, and the effects of weapons and projectiles. Total size of the Kummersdorf Firing Range was 878.1 hectares. In 1913, the dropping of bombs from the LZ 13 Hansa airship and Wright biplanes was investigated. In the 1920s, secret development started in the areas of artillery, armored forces, mo ...

Light Tank
A light tank is a tank variant initially designed for rapid movements in and out of combat, to outmaneuver heavier tanks. It is smaller in size with thinner armor and a less powerful main gun, tailored for better tactical mobility and ease of transport and logistics. They are primarily employed in the screening, armored reconnaissance, skirmishing, artillery observation, and supplementing landing operations in a fire support role of expeditionary forces where larger, heavier tanks are unavailable or have difficulties operating safely or efficiently. The fast light tank was a major feature of the pre-World War II army buildup, where it was expected they would be used to exploit breakthroughs in enemy lines created by slower, heavier tanks, with the goal of disrupting communications and supply lines. Numerous small tank designs and "tankettes" were developed during this period and known under a variety of names, including the " combat car". Early light tank designs were gene ...

Youmans had previously worked as an editor for the weekly ''Appleton's Journal'' and persuaded them to publish his new journal. Early issues were mostly reprints of English periodicals. The journal became an outlet for writings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Super-heavy Tank
A super-heavy tank or super heavy tank is any tank that is notably beyond the standard of the class heavy tank in either size or weight relative to contemporary vehicles. Programs have been initiated on several occasions with the aim of creating an extremely resilient vehicle for penetrating enemy formations without fear of being destroyed in combat; however, only a few examples were built, and there is little evidence of any super heavy tank having seen combat. Examples were designed in the First and Second World Wars, along with a few during the Cold War. History First World War left, Model of the Flying Elephant design The first super-heavy tank was designed by the Russian naval engineer Vasily Mendeleyev who worked on the project from 1911 to 1915. The tank was envisioned to be invulnerable to almost all contemporary threats but remained on paper due to its high construction cost. Following the production of their first tanks, the British "Flying Elephant" was desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
