Ansaldo A-1 Balilla
The Ansaldo A.1, nicknamed "Balilla" after the Genoan folk-hero, was Italy's only domestically-designed fighter aircraft of World War I to be produced in Italy. Arriving too late to see any real action, it was however used by both Poland and the Soviet Union in the Polish-Soviet War of 1919–1921. Development The A.1 resulted from ongoing efforts by the Ansaldo company to create a modern fighter. The SVA.5 had proved unsuitable in this role, although it made an excellent reconnaissance aircraft and had been ordered into production as such. Ansaldo engineer Giuseppe Brezzi revised the SVA.5, reducing the size of the upper wing, and replacing the SVA's transverse Warren truss interplane struts, which had eliminated the need for spanwise-exposed flying and landing wires, with conventional wire braced struts. While this produced more drag, it increased the stiffness of the wing structure, improving manoeuvrability. Engine power was increased to and a safety system to jettison t ...

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 ...

Interplane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more imp ...

The state eventually disintegrated into rival regional po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Army
The Workers' and Peasants' Red Army (Russian: Рабо́че-крестья́нская Кра́сная армия),) often shortened to the Red Army, was the army and air force of the Russian Soviet Federative Socialist Republic and, after 1922, the Union of Soviet Socialist Republics. The army was established in January 1918. The Bolsheviks raised an army to oppose the military confederations (especially the various groups collectively known as the White Army) of their adversaries during the Russian Civil War. Starting in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in 1991. The Red Army provided the largest land force in the Allied victory in the European theatre of World War II, and its invasion of Manchuria assisted the unconditional surrender of Imperial Japan. During operations on the Eastern Front, it accounted for 75–80% of casual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kościuszko's Squadron
The Kościuszko Squadron (officially: Polish 7th Air Escadrille) was a Polish Air Force fighter squadron established in late 1919 by Merian C. Cooper, an American aviator who would go on to direct the film ''King Kong'' in 1933. The unit was named after Tadeusz Kościuszko, and Major Cedric Fauntleroy became its commander. The squadron's insignia was designed by Elliot William Chess (1899–1962), an American pilot serving with the Polish Army during the Polish–Soviet War. To encourage the recruitment of Americans of Polish descent, the Polish military set up a unit called the Polish–American Air Group. The most famous successor to this original Kościuszko Squadron was the World War II No. 303 "Kościuszko" Polish Fighter Squadron (Warszawski im. Tadeusza Kościuszki), the most successful fighter squadron in the Battle of Britain. Formation First formed after Poland regained independence following World War I, it consisted of a small group of American volunteers independ ...

Armistice
An armistice is a formal agreement of warring parties to stop fighting. It is not necessarily the end of a war, as it may constitute only a cessation of hostilities while an attempt is made to negotiate a lasting peace. It is derived from the Latin ''arma'', meaning "arms" (as in weapons) and ''-stitium'', meaning "a stopping". The United Nations Security Council often imposes, or tries to impose, cease-fire resolutions on parties in modern conflicts. Armistices are always negotiated between the parties themselves and are thus generally seen as more binding than non-mandatory UN cease-fire resolutions in modern international law. An armistice is a '' modus vivendi'' and is not the same as a peace treaty, which may take months or even years to agree on. The 1953 Korean War Armistice Agreement is a major example of an armistice which has not been followed by a peace treaty. An armistice is also different from a truce or ceasefire, which refer to a temporary cessation of hostiliti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonio Locatelli
Antonio Locatelli (19 April 1895 – 27 June 1936) was a pioneering Italian aviator and National Fascist Party legislator. He served in Gabriele d'Annunzio's air squadron during the war against Austria and was decorated. After the war he became a deputy to Parliament. In 1924 he attempted a transatlantic flight but was forced down into the seas off Greenland, whence he was rescued. He was killed during the Second Italo-Ethiopian War. Early life Locatelli was the son of Samuel Locatelli and Anna Gelfi, a family of modest financial standing in Bergamo, Italy. From 1908 until his graduation in 1913, he attended the Bergamo Industrial Institute. He was a keen mountaineer in his youth, climbing the Adamello, Trentino, with his brother Carlo.

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
