Chyetverikov
OKB Chyetverikov was a Soviet aircraft design bureau headed by designer Igor Vyacheslavovich Chyetverikov at the TsAGI (''Tsentrahl'nyy Aerodinamicheskiy i Ghidrodinamicheskiy Institoot''- central aerodynamics and hydrodynamics institute) Menzhinskii factory in 1931 in order to produce flying boat designs. Overview Chyetverikov, Igor Vyacheslavovich (1909–1987), was a Soviet aircraft designer, and a Candidate in Technical Sciences (1951). After completion of the Institute of the railroad and highway engineers, from 1928 he worked in D.P.Grigorovich’s OKB, where he conducted static and flight tests of training biplane MU-2. After the arrest of Grigorovich, he worked in Richard KB. With the departure of Richard, KB MOS was transferred to TsKB (''Tsentrahl'noye konstrooktorskoye byuro'' - central construction bureau) TsAGI (''Tsentrahl'nyy Aerodinamicheskiy i Ghidrodinamicheskiy Institoot''- central aerodynamics and hydrodynamics institute) in the name of N.

Chyetverikov ARK-3
The Chyetverikov ARK-3 (''ARKtichyeskii'' - arctic) was a multi-role flying boat designed for Arctic operations that was built in the Soviet Union from 1933. It featured a conventional flying boat hull, with high cantilever wings equipped with floats at mid-span. The two piston engines were mounted in tractor-pusher fashion on a pylon above the fuselage. Development In 1933 Chyetverikov had the design for a compact twin engined flying-boat ready for further development, which he proposed to the Glavsyevmorput (''Glavsyevmorput'' – chief administration of northern sea routes) as a multi-role Arctic aircraft, and an order for a prototype was made, setting up Chyetverikov in his own OKB (design bureau). The ARK-3 was of mixed construction, with a long Duralumin stressed skin fuselage; wooden wings of MOS-27 aerofoil section; duralumin tubing tail surfaces; and ailerons with fabric covering. The dual control enclosed cockpit housed two pilots sided by side with two gunners/ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chyetverikov OSGA-101
The SPL (''Samolyet dlya Podvodnikh Lodok'' – aeroplane for submarine boats) (a.k.a. OSGA-101, and Gidro-1) was a submarine borne flying boat designed and built in the USSR from 1931. Development After successful trials by the Royal Navy, with submarine borne aircraft, using the Parnall Peto and the M-class submarines, the V-MF (''Voenno-morskoj flot'' – Naval Fleet") wanted to deploy aircraft from cruiser submarines for open sea reconnaissance. In 1931 Chyetverikov had given a proposal for a submarine-launched folding flying boat to the head of TsKB (''Tsentrahl'noye Konstrooktorskoye byuro'' – central construction bureau) but nothing was heard for two years until the NII (''Naoochno-Issledovatel'skiy Institoot '' – scientific test institute) placed an order for two prototypes of the SPL. To prove the design, aerodynamically and hydrodynamically, Chyetverikov designed and built a non-folding version of the SPL with manually retracting landing gear designated OSGA-101. ...

Chyetverikov MDR-3
The MDR-3 (a.k.a.11) was a long-range flying boat designed and built in the USSR from 1931. Development In 1931, Chyetverikov was commissioned to design a new long-range flying boat for MA (''Morskaya Aviatsiya'' – naval aviation). Chyetverikov used few new parts, borrowing wings, tailplane and engine nacelles (mounted above the wing) from the Grigorovich TB-5 and a scaled-up Grigorovich ROM-2 fuselage. The use of ready designed or built components led to quick construction of the prototype which was ready for flight tests in Dec 1931. These commenced in January 1932 after the aircraft was transported to Sevastopol in the Crimea. Despite fast construction and excellent structural qualities, results of the flight tests were disappointing. Takeoff time was 36 seconds, climb rate less than a metre per second and the ceiling was only 2,200m. As a result project was transferred to KOSOS (''Konstrooktorskiy Otdel Sektora Opytnovo Stroitel'stva'' – section of experimental aeropl ...

Chyetverikov MDR-6
The Chyetverikov MDR-6 was a 1930s Soviet Union reconnaissance flying-boat aircraft, and the only successful aircraft designed by the design bureau led by Igor Chyetverikov. Development First flying in July 1937, the MDR-6 was a two-engined high-wing monoplane of all-metal stressed skin construction. The prototype was powered by two M-25 radial engines. A production run of 20 units powered by M-63 engines were produced in 1940 and 1941. All the aircraft were withdrawn from service in 1942 due to structural problems.Gunston 1995 Several progressively advanced prototypes were built from 1939 to 1945, but no further production ensued.

Arado Ar 234
The Arado Ar 234 ''Blitz'' (English: lightning) is a jet-powered bomber designed and produced by the German aircraft manufacturer Arado. It was the world's first operational turbojet-powered bomber, seeing service during the final years of the Second World War. Development of the Ar 234 can be traced back to the latter half of 1940 and the request to tender from the Ministry of Aviation to produce a jet-powered high-speed reconnaissance aircraft. Arado was the only respondent with their ''E.370'' design. While its range was beneath that of the Ministry's specification, an initial order for two prototypes was promptly issued to the company, designated ''Ar 234''. While both of the prototypes had been mostly completed prior to the end of 1941, the Junkers Jumo 004 turbojet engines were not available prior to February 1943. Due to engine unreliability, the maiden flight of the Ar 234 V1 was delayed until 30 July 1943. In addition to the original reconnaissance-orientated ''Ar 234 ...

Chief Directorate Of The Northern Sea Route
The Chief Directorate of the Northern Sea Route (), also known as Glavsevmorput or GUSMP (), was a Soviet government organization in charge of the maritime Northern Sea Route, established in January 1932 and dissolved in 1964. History The organization traces its roots to AO Komseverput () or KSMP, a shipping company established by the Aleksandr Kolchak, Kolchak government in 1919 and subsequently nationalized by the Bolsheviks. In May 1931 AO Komseverput was reorganized into VO Glavkomseverput; the organization employed 35,000 men scattered all over Arctic, as well as a sizable staff in Moscow and in other mainland cities. A new office, Glavsevmorput, was established in December 1932 and absorbed VO Glavkomseverput in May 1933. Overall management was assigned to the Arctic explorer Otto Schmidt, who had previously managed the Arctic Institute (VAI, later AANII). Glavsevmorput had its own Polar Air service Aviaarktika, headed by Mark Shevelev. Glavsevmorput, in addition to running ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
