Chetverikov 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 Crimean Peninsula, 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 e ...

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 Wikimedia project, 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 Magazine, 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".

List Of Flying Boats And Floatplanes
The following is a list of seaplanes, which includes floatplanes and flying boats. A seaplane is any airplane that has the capability of landing and taking off from water, while an amphibian is a seaplane which can also operate from land. (They do not include rotorcraft, or ground-effect vehicles which can only skim along close to the water) A flying boat relies on its main hull for buoyancy, while a floatplane has a conventional aircraft fuselage fitted with external floats. In some locales, the term "seaplane" is used as a synonym for floatplane. List A small number of seaplanes have retractable beaching gear, which is not capable of being used for landings and takeoffs, but these remain flying boats or floatplanes and are not amphibians. Many floatplanes, especially those since 1945, can have either conventional floats for operating just from water, or amphibious floats, which have retractable undercarriage built into them. Some experimental flying boats have used skis ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Chyetverikov Aircraft
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.

Flying Boats
A flying boat is a type of fixed-winged aircraft, fixed-winged seaplane with a hull (watercraft), hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing Float (nautical), floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground Takeoff, takeoff and Landing, landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. ...

1930s Soviet Patrol Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor. Pertinax is forced to reorganize the handling of finances, which were wrecked under Commodus, to reestablish discipline in the Roman army, and to suspend the food programs established by Trajan, provoking the ire of the Praetorian Guard. * March 28 – Pertinax is assassinated by members of the Praetorian Guard, who storm the imperial palace.

Short Knuckleduster
The Short R.24/31 (or Short S.18 and nicknamed the ''Knuckleduster'') was a British twin-engined, high-wing cantilever gull winged monoplane flying-boat designed and built by Short to Air Ministry specification R.24/31 for a "General Purpose Open Sea Patrol Flying Boat". The contract also specified the use of the experimental Rolls-Royce Goshawk engine. The Saunders-Roe London and the Supermarine Stranraer competed successfully for this contract. Although it never saw military service, the Knuckleduster provided useful information on the steam-cooling of engines and the handling of monoplane flying-boats; much experimental data gathered contributed to the design of the successful Empire and Short Sunderland aircraft.Barnes and James 1989, p. 284. Design and development The British Air Ministry issued its Specification R.24/31 for a "General Purpose Open Sea Patrol Flying Boat" in 1931 and ordered one prototype from each of Saunders-Roe, Supermarine and Shorts.

Crimean Peninsula
Crimea, crh, Къырым, Qırım, grc, Κιμμερία / Ταυρική, translit=Kimmería / Taurikḗ ( ) is a peninsula in Ukraine, on the northern coast of the Black Sea, that has been occupied by Russia since 2014. It has a population of 2.4 million. The peninsula is almost entirely surrounded by the Black Sea and the smaller Sea of Azov. The Isthmus of Perekop connects the peninsula to Kherson Oblast in mainland Ukraine. To the east, the Crimean Bridge, constructed in 2018, spans the Strait of Kerch, linking the peninsula with Krasnodar Krai in Russia. The Arabat Spit, located to the northeast, is a narrow strip of land that separates the Sivash lagoons from the Sea of Azov. Across the Black Sea to the west lies Romania and to the south is Turkey. Crimea (called the Tauric Peninsula until the early modern period) has historically been at the boundary between the classical world and the steppe. Greeks colonized its southern fringe and were absorbed by the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
