Ansaldo A.1
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 ...

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".

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 struts, 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 aeroplanes, 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 ...

Red Army
The Workers' and Peasants' Red Army, often shortened to the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army (which embodied the main component of the Soviet Armed Forces alongside the Soviet Navy) was renamed the "Soviet Army". Following the dissolution of the Soviet Union it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army. The Red Army provided the largest land warfare, ground force in the Allies of World War II, Allied victory in the European theatre of World War II, and its Soviet invasion of Manchuria, invasion of Manchuria assisted the un ...

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 (1933 film), ''King Kong'' in 1933, then to advocate for McCarthyism in 1950s. 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 (Polish) Squadron RAF, 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 regai ...

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, ceasefire 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 ho ... [...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 :it:Parco naturale Adamello Brenta, Adamello, Trentino, with his brother Carlo. He then became chief technician at the Ansaldo di Cornigliano Ligure. Aviator Having joined a flying unit of the army, Locatelli was granted his pilot's licence in 1915.

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, 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 or fuselage, thus imparting a turning or 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 afterend. Often rudders are shaped to minimize 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 link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. H ...
