Bartini Stal-7
The Bartini Stal-7 was a twin-engined transport aircraft designed and produced in the Soviet Union from 1934. Development Aeroflot issued a requirement for two transport aircraft types. Bartini began design work in October 1934 on an aircraft to meet the larger 10/12 passenger specification. Initially Bartini intended the Stal-7 to use a steel tube truss airframe, with fabric covering, but problems with complexity and the flexibility of the truss structure led Bartini to re-design the aircraft with a light-alloy monocoque structure. The hydraulically retractable main undercarriage legs retracted rearwards into the engine nacelles, which were positioned at the junction of the inverted gull wings. The trailing edges had hydraulically operated flaps inboard and ailerons outboard. Both the wings and tail surfaces were sharply tapered and the inboard wing sections sloped sharply upwards to pass through the fuselage cabin. Flight testing began in the spring of 1937 piloted by N.

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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".

Mid-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 wings. 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 ...

Bartini Aircraft
Robert Ludvigovich Bartini (; 14 May 1897 – 6 December 1974) was a Hungarian-born Soviet aircraft designer and scientist, involved in the development of numerous successful and experimental aircraft projects. A pioneer of amphibious aircraft and ground-effect vehicles, Bartini was one of the most famous engineers in the Soviet Union, nicknamed ''Barone Rosso'' (Red Baron) because of his noble descent.Ciampaglia 2009, p. 28. Biography Early life Robert Bartini was born on 14 May 1897, in Fiume, Kingdom of Hungary, Austro-Hungarian Empire (now Rijeka, Croatia), the son of an unmarried 17-year-old girl of noble origins. Bartini's biological father, Lajos Orosdy (de Orosd et Bö), in Italian: Lodovico Oros de Bartini, was a baron of the Austro-Hungarian nobility and the Lieutenant Governor of Fiume. His grand-father Adolf converted together with his father to Roman Catholic faith in Pest (now Budapest) in 1826. Adolf changed his name from Schnabel in 1848. "Our family is of J ...

1930s Soviet Airliners
Year 193 ( CXCIII) was a common year starting on Monday 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.

Douglas DC-1
The Douglas DC-1 was the first model of the famous American DC (Douglas Commercial) commercial transport aircraft series. Although only one example of the DC-1 was produced, the design was the basis for the DC-2 and DC-3, the latter being one of the most successful aircraft in the history of aviation. Design and development Development of the DC-1 can be traced back to the 1931 crash of a TWA airliner, a Fokker F-10 trimotor in which a wing failed, likely because water had seeped between the layers of the wood laminate and dissolved the glue holding the layers together. Following the accident, the Aeronautics Branch of the U.S. Department of Commerce placed stringent restrictions on the use of wooden wings on passenger airliners.Friedman and Friedman, ''Aeroplane Monthly'' May 2001, pp. 34–40.O'Leary, ''Aeroplane Monthly'' February 2007, p. 71.

Bomber
A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch aerial torpedo, torpedoes, or deploy air-launched cruise missiles. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure, reducing industrial output, or inflicting massive civilian casualties to an extent deemed to force surrender. Tactical bombing is aimed at countering enemy military activity and in supporting offensive operations, and is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping. Bombs were first dropped from an aircraft during the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Seco ...

Sevastopol
Sevastopol ( ), sometimes written Sebastopol, is the largest city in Crimea and a major port on the Black Sea. Due to its strategic location and the navigability of the city's harbours, Sevastopol has been an important port and naval base throughout its history. Since the city's founding in 1783 it has been a major base for Russia's Black Sea Fleet. During the Cold War of the 20th century, it was a closed city. The total administrative area is and includes a significant amount of rural land. The urban population, largely concentrated around Sevastopol Bay, is 479,394, and the total population is 547,820. Sevastopol, along with the rest of Crimea, is internationally recognised as part of Ukraine, and under the Ukrainian legal framework, it is administratively one of two cities with special status (the other being Kyiv). However, it has been occupied by Russia since 27 February 2014, before Russia annexed Crimea on 18 March 2014 and gave it the status of a federal city of R ...
