Cheranovsky BICh-1
Boris Ivanovich Cheranovsky (, alternatively romanized as Chyeranovskii; 1 (13) July 1896 – 17 December 1960) was a Soviet aircraft designer, notable for creating aircraft with a characteristic tailless parabola, 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, Ukraine. By profession he was a painter and sculptor, but in 1920 became interested in aviation. In 1921, for the first time, he proposed a "flying wing" aircraft. Colleagues did not believe the idea could be implemented, but within two years, Cheranovsky had completed the relevant work and presented prototypes of the technology. Tests at the airfield began on April 1, 1923, with the BICh-1. From 1924 to 1927 he studied at the Air Force Academy. Throughout his career he focused in the design and construction of flying-wing aircraft. For his services to aviation, Cheranovsky was awarded the Order of ...

Parabola
In mathematics, a parabola is a plane curve which is Reflection symmetry, mirror-symmetrical and is approximately U-shaped. It fits several superficially different Mathematics, mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a Point (geometry), point (the Focus (geometry), focus) and a Line (geometry), line (the Directrix (conic section), directrix). The focus does not lie on the directrix. The parabola is the locus (mathematics), locus of points in that plane that are equidistant from 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 (geometry), plane Parallel (geometry), parallel to another plane that is tangential to the conical surface. The graph of a function, graph of a quadratic function y=ax^2+bx+ c (with a\neq 0 ) is a parabola with its axis parallel to the -axis. Conversely, every ...

BICh-3
The BICh-3 () was a tailless research aircraft designed and built in the USSR in 1926. Development After Cheranovsky's first tailless flying wing gliders, the Cheranovsky BICh-1, BICh-1 and Cheranovsky BICh-2, BICh-2, he continued developing the concept with the BICh-3. The BICh-3 was built of wood with a parabolic wing 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.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Designers
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
