Development and design The R-5 was developed by the design bureau led by Nikolai Nikolaevich Polikarpov А. С. Яковлев. О жизни и о себе (записки авиаконструктора). 2-е изд., доп.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Soviet Invasion Of Poland (1939)
The Soviet invasion of Poland was a military operation by the Soviet Union without a formal declaration of war. On 17 September 1939, the Soviet Union invaded Poland from the east, 16 days after Nazi Germany invaded Poland from the west. Subsequent military operations lasted for the following 20 days and ended on 6 October 1939 with the two-way division and annexation of the entire territory of the Second Polish Republic by Nazi Germany and the Soviet Union. This division is sometimes called the Fourth Partition of Poland. The Soviet (as well as German) invasion of Poland was indirectly indicated in the "secret protocol" of the Molotov–Ribbentrop Pact signed on 23 August 1939, which divided Poland into "spheres of influence" of the two powers. German and Soviet cooperation in the invasion of Poland has been described as co-belligerence. The Red Army, which vastly outnumbered the Polish defenders, achieved its targets, encountering only limited resistance. Some 320,000 Poles ...

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]   |

Sheng Shicai
Sheng Shicai (; 3 December 189513 July 1970) was a Chinese warlord who ruled Xinjiang from 1933 to 1944. Sheng's rise to power started with a coup d'état in 1933 when he was appointed the ''duban'' or Military Governor of Xinjiang. His rule over Xinjiang is marked by close cooperation with the Soviet Union, allowing the Soviets trade monopoly and exploitation of resources, which effectively made Xinjiang a Soviet puppet state. The Soviet era ended in 1942, when Sheng approached the Nationalist Chinese government, but still retained much power over the province. He was dismissed from post in 1944 and named Minister of Agriculture and Forestry. Growing animosity against him led the government to dismiss him again and appoint to a military post. At the end of the Chinese Civil War, Sheng fled mainland China to Taiwan with the rest of Kuomintang. Sheng Shicai was a Manchurian-born Han Chinese, educated in Tokyo, Japan, where he studied political economy and later attended the Imp ...
