Cheranovsky RP-1
Boris Ivanovich Cheranovsky (russian: Борис Иванович Черановский, alternatively romanized as Chyeranovskii; 1 (13) July 1896 – 17 December 1960) was a Soviet aircraft designer, notable for creating aircraft with a characteristic tailless parabolic wing. — the BICh-1 and BICh-2 gliders from 1924, and the powered BICh-3 later. B. I. Cheranovsky was born on either 1 or 13 July 1896 in Pavlovychi, Volhynian Governorate, Russia. By profession he was painter and sculptor, but in 1920 became interested in aviation. In 1921, for the first time, he proposed a project of a "flying wing" type of aircraft. Colleagues of the aircraft designer did not believe in the possibility of implementing the idea. In two years, the specialist managed to complete the relevant works and presented prototypes of the technology. Tests at the airfield began on April 1, 1923. It was then that BICh-1 was tested. From 1924 to 1927 he studied at the Air Force Academy. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parabola
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix). The focus does not lie on the directrix. The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus. Another description of a parabola is as a conic section, created from the intersection of a right circular conical surface and a plane parallel to another plane that is tangential to the conical surface. The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola through the middle) is called the "axis of symmetry". The point where the parabola intersects its axis of symmetry is called the "vertex" and is the point where the parabola is most sharply curved. The ...

BICh-3
The BICh-3 (russian: БИЧ-3) was a tailless research aircraft designed and built in the USSR in 1926. Development After Cheranovsky's first tailless flying wing gliders, the BICh-1 and BICh-2, he continued developing the concept with the BICh-3. The BICh-3 was built of wood with a parabolic wing Parabolic usually refers to something in a shape of a parabola, but may also refer to a parable. Parabolic may refer to: *In mathematics: **In elementary mathematics, especially elementary geometry: ** Parabolic coordinates **Parabolic cylindrica ... having a straight trailing edge and a curved leading edge. The cockpit was faired into a large fin and rudder. The undercarriage consisted of a faired central mono-wheel with wing-tip skids. The BICh-3 was flown in Moscow in 1926. It was found to be unstable in initial tests leading to modifications that improved the handling sufficiently for it to be cleared as safe to fly.

Volhynian Governorate
Volhynian Governorate or Volyn Governorate (russian: Волы́нская губе́рния, translit=Volynskaja gubernija, uk, Волинська губернія, translit=Volynska huberniia) was an administrative-territorial unit initially of the Russian Empire, created at the end of 1796 after the Third Partition of Poland from the territory of the short-lived Volhynian Vice-royalty and Wołyń Voivodeship (1569–1795), Wołyń Voivodeship. After the Peace of Riga, part of the governorate became the Wołyń Voivodeship (1921–1939), new Wołyń Voivodeship in the Second Polish Republic, while the other part stayed as a part of the Ukrainian SSR until 1925 when it was abolished on resolution of the All-Ukrainian Central Executive Committee and Counsel of People's Commissars. History Until 1796 the guberniya was administrated as a namestnichestvo (Vice-royalty). It was initially centred in Iziaslav, Ukraine, Iziaslav and was called the Izyaslav namesnichestvo.

1960 Deaths
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Soviet Engineers
Science and technology in the Soviet Union served as an important part of national politics, practices, and identity. From the time of Lenin until the dissolution of the USSR in the early 1990s, both science and technology were intimately linked to the ideology and practical functioning of the Soviet state, and were pursued along paths both similar and distinct from models in other countries. Many great scientists who worked in Imperial Russia, such as Konstantin Tsiolkovsky, continued work in the USSR and gave birth to Soviet science. The Soviet government made the development and advancement of science a national priority, emphasizing science at all levels of education and showering top scientists with honours. Very large numbers of engineers graduated every year. Soviet scientists won acclaim in several fields, marked by a highly developed pure science and innovation at the theoretical level, though interpretation and application fell short. They were at the cutting edge of sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
