Beriev Be-10
The Beriev Be-10, also known as Izdelye M, (NATO reporting name: Mallow) was a twin engined, turbojet powered, flying-boat, patrol bomber built by the Soviet Union from 1955. The Be-10 is sometimes referred to as the M-10, though this designation is believed to apply only to the modified Be-10 that established 12 FAI world records in 1961, Bort no. ''40 Yellow'', still holding class records for speed and altitude. Design and development The Be-10 was designed in response to Council of Ministers of the Soviet Union directive No.2622-1105ss which called for a turbojet-powered flying boat for open-sea reconnaissance, bombing, torpedo attack and mine-laying. Stipulated performance was to include a maximum speed of and the ability to operate in wave heights of at wind speeds up to with submission for state acceptance trials in November 1955. OKB-49, under the leadership of Gheorgiy M. Beriev took up the challenge of designing and building the ''izdeliye M'' (Beriev OKB in-house ...

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 ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Metal Fatigue
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting ...

Tushino
Tushino ( rus, Тушино, p=ˈtuʂɨnə) is a former village and town to the north of Moscow, which has been part of the city's area since 1960. Between 1939 and 1960, Tushino was classed as a separate town. The Skhodnya River flows across the southern part of Tushino. History The village was attested since the late 14th century as an estate of boyar Vasili Ivanovich Kvashnin-Tusha and later his sons Pyotr and Semyon. In the middle of the 16th century, the village and the nearby Saviour Monastery were acquired by the Troitse-Sergiyeva Lavra. One of the finest of Russian tent-like churches was built in the monastery under Ivan the Terrible. In the late 16th century, the monastery used to provide lodging for foreign diplomatic missions before their arrival in Moscow. During the Time of Troubles, False Dmitry II and his supporters settled in Tushino between 1608 and 1610. The Tushino camp was a replica of the Muscovite court, having its own prikazes and the Patriarch. From ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Show
An air show (or airshow, air fair, air tattoo) is a public event where aircraft are exhibited. They often include aerobatics demonstrations, without they are called "static air shows" with aircraft parked on the ground. The largest air show measured by number of exhibitors and size of exhibit space is Le Bourget followed by Farnborough, while Dubai air show and Singapore Air Show are both claiming the third place. The largest air show or fly-in by number of participating airplanes is EAA AirVenture Oshkosh, commonly known as "Oshkosh" after its location in Wisconsin, with approximately 10,000 airplanes participating each year. The biggest military airshow in the world is the Royal International Air Tattoo, at RAF Fairford in England. Outline Some airshows are held as a business venture or as a trade event where aircraft, avionics and other services are promoted to potential customers. Many air shows are held in support of local, national or military charities. Military ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Lake Donuzlav
Lake Donuzlav ( rus, Донузлав) also referred to as Donuzlav Bay is the deepest lakeOliferov, A.M. Donuzlav (ДОНУЗЛА́В)'. Encyclopedia of Modern Ukraine. of Crimea () and biggest in Chornomorske Raion (). It is a protected landscape and recreational park of the Autonomous Republic of Crimea. In practice it is no longer a lake but rather a bay since 1961, when a sandy spit ( wide) separating it from the Black Sea was dug out with a 200-metre width channel. The lake is as salty as the sea near its mouth but bottom springs make the water much more sweet near the head. Overview Donuzlav is well known for a top secret naval base that was established here in 1960s as the Soviet Crimean Naval Base. The base was particularly notable for housing air-cushioned landing craft (). Following the dissolution of the Soviet Union, the base was passed to the Armed Forces of Ukraine and was one of the three main naval bases as the Southern Naval Base (Ukraine).

Southern Naval Base (Ukraine)
Southern Naval Base ( uk, Південна військово-морська база, Russian: Южная военно-морская база) was a naval base of the Armed Forces of Ukraine located in the town of Novoozerne (part of Yevpatoria city municipality) at the Donuzlav Bay in the western part of Crimea. The base was reorganized in place of the Crimea Naval Base of the Soviet Union which completely occupyied the southern shores of Donuzlav Bay and included hovercraft berths, Donuzlav Air Station, and a submarine base. Most of the former base is disassembled, while the former Donuzlav Air Station is non-operational. Donuzlav Bay is separated from the Black Sea by two sandspits which serve as a small freight port of the Yevpatoriya Commercial Trade Port located in the city. History The naval base was established by Ukraine in 1996, having previously been a Soviet naval base from 1976 to 1991, and then a Russian base. It celebrated its 15th anniversary in 2011.

Lyul'ka AL-7F
The Lyulka AL-7 was a turbojet designed by Arkhip Mikhailovich Lyulka and produced by his Lyulka design bureau. The engine was produced between 1954 and 1970.Gunston 1989, p.100. Design and development The AL-7 had supersonic airflow through the first stage of the compressor. TR-7 prototype, developing 6,500 kgf (14,330 lbf, 63.7 kN) of thrust, was tested in 1952, and the engine was initially intended for Ilyushin's Il-54 bomber. The afterburning AL-7F version was created in 1953. In April 1956, the Sukhoi S-1 prototype, equipped with the AL-7F, exceeded Mach 2 at 18,000 m (70,900 ft), which led to the production of the Su-7 'Fitter' and Su-9 'Fishpot', equipped with this engine.Green, William and Gordon Swanborough. ''The Great Book of Fighters.'' St. Paul, Minnesota: MBI Publishing, 2001. . Later, the engine was adopted for the Tu-128 'Fiddler' in 1960, and for the AS-3 'Kangaroo' cruise missile.

Dihedral (aircraft)
In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect of sideslip on the rolling of the aircraft. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
