Kurumoch International Airport
Kurumoch International Airport (russian: Международный аэропорт "Курумоч") is the international airport of Samara, Russia, located 35 km (22 mi) north of the city. Besides Samara, the airport serves Tolyatti – the second largest city in the region. The name of the airport originated from the closest village Kurumoch 7 km (4 mi) southwest. Kurumoch was used as a hub for Samara Airlines until the airline's bankruptcy. In 2011, Kurumoch was acquired by the largest airport holding and management company in Russia, Airports of Regions. Description Kurumoch became officially operational on 15 May 1961, as a domestic airport. The airport is notable for being the largest airport (by passenger traffic) in the Volga Federal District. In 2017, Kurumoch Airport served 2,649,426 passengers, a 26.6% increase from the previous year. Over 30 airlines made 12,959 departures to 43 destinations in 2017, in addition to 3,483 tons of cargo being p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonov An-10
The Antonov An-10 Ukraina ( ua, Антонов Ан-10 Україна, , Ukraine; NATO reporting name: Cat) is a four-engined turboprop passenger transport aircraft designed in the Soviet Union. Design and development Development of a four-engined airliner intended for use on routes from began at the end of 1955. Inspired by the Izdeliye N (''Izdeliye'' – article or product) passenger version of the Antonov An-8, the Antonov design bureau developed the Izdeliye U ("U" for "Universal"), a four-engined aircraft with a similar layout to the An-8, but with increased dimensions and a circular-section pressurised fuselage. Early in the design process the choice of engines was between the Kuznetsov NK-4 and the Ivchenko AI-20, and despite superior performance the Kuznetsov NK-4 was eliminated and the Ivchenko AI-20 selected, partly due to the Central Committee of the Communist Party of Ukraine which wanted as much as possible produced in Ukraine, where the Ivchenko factory was. ...

Aeroflot
PJSC AeroflotRussian Airlines (russian: ПАО "Аэрофло́т — Росси́йские авиали́нии", ), commonly known as Aeroflot ( or ; russian: Аэрофлот, , ), is the flag carrier and the largest airline of Russia. The airline was founded in 1923, making Aeroflot one of the oldest active airlines in the world. Aeroflot is headquartered in the Central Administrative Okrug, Moscow, with its hub being Sheremetyevo International Airport. Before the 2022 Russian invasion of Ukraine, the airline flew to 146 destinations in 52 countries, excluding codeshared services. The number of destinations was significantly reduced after many countries banned Russian aircraft; as of 8 March 2022, Aeroflot flies only to destinations in Russia and Belarus. From its inception to the early 1990s, Aeroflot was the flag carrier and a state-owned enterprise of the Soviet Union (USSR). During this time, Aeroflot grew its fleet to over five thousand domestically made aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luhansk
Luhansk (, ; uk, Луганськ, ), also known as Lugansk (, ; russian: Луганск, ), is a city in what is internationally recognised as Ukraine, although it is administered by Russia as capital of the Luhansk People's Republic (LPR). As of 2021, the population was estimated to be 399,559, making Luhansk the most populous city in the region and the 12th largest in Ukraine. In 2001, nearly half of the population was ethnically Ukrainian, and 47% was ethnically Russian. Luhansk has been the capital and administrative center of Luhansk Oblast, although the Ukrainian administration was relocated to Sievierodonetsk when the War in Donbas broke out following the establishment of LPR. Etymology Luhansk was named after the Luhan River, which flows through the city. According to folk etymology, the name is also derived to the word "Luh" (Ukrainian: Луг), which means "meadow", referring to the floodplains around the river. History The city traces its history to 1795 whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advisories'' (known as ''flight info ...

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt B ...

Elevator (aeronautics)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

Rib (aeronautics)
In an aircraft, ribs are forming elements of the structure of a wing, especially in traditional construction. By analogy with the anatomical definition of "rib", the ribs attach to the main Spar (aviation), spar, and by being repeated at frequent intervals, form a skeletal shape for the wing. Usually ribs incorporate the airfoil shape of the wing, and the skin adopts this shape when stretched over the ribs. Type of ribs There are several types of ribs. Form-ribs, plate-type ribs, truss ribs, closed-ribs, forged ribs and milled ribs, where form-ribs are used for light to medium loading and milled ribs offer the greatest strength. * Form-ribs are made from a sheet of metal bent into shape, such as a U-profile. This profile is placed on the skin, just like a stringer (aircraft), stringer, but then in the other direction. * Plate-type ribs consist of sheet-metal, which has upturned edges and (often has) weight-saving holes cut into it. * Truss ribs are built up out of profiles that a ...

Shear Strength
In engineering, shear strength is the strength of a material or component against the type of yield or structural failure when the material or component fails in shear. A shear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force. When a paper is cut with scissors, the paper fails in shear. In structural and mechanical engineering, the shear strength of a component is important for designing the dimensions and materials to be used for the manufacture or construction of the component (e.g. beams, plates, or bolts). In a reinforced concrete beam, the main purpose of reinforcing bar (rebar) stirrups is to increase the shear strength. Equations For shear stress \tau applies :\tau = \frac , where :\sigma_1 is major principal stress and :\sigma_3 is minor principal stress. In general: ductile materials (e.g. aluminum) fail in shear, whereas brittle materials (e.g. cast iron) fail in tension. Se ...

Fatigue (material)
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 ...

Aeroflot Accidents And Incidents
Founded in 1923, Aeroflot, the flag carrier and largest airline of Russia (and formerly the Soviet Union) (formerly the world's largest airline), has had a high number of fatal crashes, with a total of 8,231 passengers dying in Aeroflot crashes according to the Aircraft Crashes Record Office, mostly during the Soviet-era, about five times more than any other airline. From 1946 to 1989, the carrier was involved in 721 incidents. From 1995 to 2017, the carrier was involved in 10 incidents. In 2013, AirlineRatings.com reported that five of the ten aircraft models involved in the highest numbers of fatal accidents were old Soviet models. Following is a list of accidents and incidents Aeroflot experienced from 1932 to the present. 1930s 1940s 1950s 1960s 1970s 1980s 1990s 2000s * On 21 September 2001, Ilyushin Il-86 (RA-86074) landed gear-up at Dubai Airport due to pilot error; all 322 passengers and crew survived, but the aircraft was written off.

Accidents And Incidents Involving The Antonov An-10
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into some ...
