A Vlaicu I
The A Vlaicu I was the first powered airplane built by Aurel Vlaicu. Design and development After flying his glider in Binţinţi, Aurel Vlaicu moved to the Kingdom of Romania. On November 1, 1909, he began the construction of his first powered airplane, the ''A. Vlaicu Nr. I'' at the Army Arsenal in Bucharest. The Romanian Ministry of War provided an initial grant of 2000 lei, and Minister of Public Education was paying Vlaicu a 300 lei monthly stipend. The A. Vlaicu Nr. I flew for the first time on June 17, 1910, over Cotroceni airfield.

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 ...

Military Exercise
A military exercise or war game is the employment of military resources in training for military operations, either exploring the effects of warfare or testing strategies without actual combat. This also serves the purpose of ensuring the combat readiness of garrisoned or deployable forces prior to deployment from a home base. While both war games and military exercises aim to simulate real conditions and scenarios for the purpose of preparing and analyzing those scenarios, the distinction between a war game and a military exercise is determined, primarily, by the involvement of actual military forces within the simulation, or lack thereof. Military exercises focus on the simulation of real, full-scale military operations in controlled hostile conditions in attempts to reproduce war time decisions and activities for training purposes or to analyze the outcome of possible war time decisions. War games, however, can be much smaller than full-scale military operations, do not typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A Vlaicu III
The A Vlaicu III was the world's first metal-built aircraft, designed and built in Romania prior to World War I. It was the third powered aircraft designed by pioneering Romanian aviator Aurel Vlaicu. Design and development Engineer and inventor Aurel Vlaicu, who was among the first pilots in Romania, began the design of the third in his series of powered aircraft in the second half of 1911. The design was based on his earlier A Vlaicu II. A nacelle underneath a parasol wing housed the pilot and a Gnome Gamma engine. Gears, chains and shafts drove two propellers, one in front of and one behind the wing; these turned in opposite directions to cancel each other's torque. Like Vlaicu's other designs, the A. Vlaicu III did not have ailerons. The pilot turned the aircraft by using the rudder, controlled by moving a tiller left or right; to control the elevators and make the aircraft go up and down, a steering wheel attached to the tiller was turned left or right. It was th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Vlaicu II
The A Vlaicu II was the second powered airplane designed and built by Aurel Vlaicu. Design and development The construction of ''A. Vlaicu Nr. II'' was started in December 1910 at the '' Școala de Arte și Meserii'' (Arts and Crafts School) in Bucharest, on a budget of 16,000 lei. It was an improved version of Vlaicu's earlier airplane, the ''A. Vlaicu Nr. I''. The ''A. Vlaicu Nr. II'' first flew in April 1911 on Cotroceni airfield in Bucharest. Operational history Between 23 and 30 June 1912 Vlaicu flew the A. Vlaicu Nr. II at the Die Internationale Flugwoche at Aspern near Vienna, competing against 42 other aviators including Roland Garros. Vlaicu won prizes totaling 7,500 Austro-Hungarian krone for precision landing, projectile throwing and tight flying around a pole. The competition number of the A. Vlaicu Nr. II was 38, painted on the left wing and stabilizer. On return from Aspern he performed demonstration flights ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotary Piston Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional radi ...

Gnome Omega
The Gnome 7 Omega (commonly called the Gnome 50 hp) is a French seven-cylinder, air-cooled aero engine produced by Gnome et Rhône. It was shown at the Paris Aero Salon held in December 1908 and was first flown in 1909. It was the world's first aviation rotary engine produced in quantity. Its introduction revolutionized the aviation industry and it was used by many early aircraft. It produced from its engine capacity. A Gnome Omega engine powers the 1912 Blackburn Monoplane, owned and operated by the Shuttleworth Collection, the oldest known airworthy British-designed aeroplane worldwide. A two-row version of the same engine was also produced, known as the Gnome 14 Omega-Omega or Gnome 100 hp. The prototype Omega engine still exists, and is on display at the United States' National Air and Space Museum. Like all early Gnome et Rhône engines the Omega featured a single pushrod driven exhaust valve on the cylinder head; the intake valve was located in the piston c ...

Romanian Air Corps
The Romanian Air Corps or Aviation Corps (RAC) ( ro, Corpul de Aviație) was the air arm of the Romanian army until the formation of the Romanian Air Force. It was established on 1 April 1913 as the Military Aeronautics Service () and subordinated to the Engineer Inspectorate, being organized in two branches – the aviation and the balloon branch. On 23 August 1915, the RAC was formed as an independent military arm and operated until 1 January 1924 when it became an equal to the Army and Navy, being redesignated as the Royal Romanian Air Force ('' Aeronautica Regală Română''). In 1913, the newly established Military Aeronautics Service participated in the Second Balkan War. Being organized in two sections, the Aeronautics Service carried out reconnaissance, liaison and leaflet dropping missions over Bulgaria. In 1915, the Air Corps gained independence from the Engineer Inspectorate. When Romania entered the First World War on the Allied side in 1916, the RAC was organized ...

Military Aviation
Military aviation comprises military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift ( air cargo) capacity to provide logistical supply to forces stationed in a war theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and warcraft. Military aircraft include bombers, fighters, transports, trainer aircraft, and reconnaissance aircraft. History The first military uses of aviation involved lighter-than-air balloons. During the Battle of Fleurus in 1794, the French observation balloon ''l'Entreprenant'' was used to monitor Austrian troop movements. The use of lighter-than-air aircraft in warfare became prevalent in the 19th century, including regular use in the American Civil War. Lighter-than-air military aviation persisted until shortly after World War II, gradually being withdrawn from various roles as heavier-than-air airc ...
