Avia BH-3
__NOTOC__ The Avia BH-3 was a fighter plane built in Czechoslovakia in 1921. Conceptually a descendant of the BH-1 sports plane, it was a braced, low-wing monoplane of conventional configuration and tailskid undercarriage. Following favourable trials in June 1921, ten examples were ordered by the Czechoslovakian Air Force. These were delivered in 1923 under the military designation B.3. The type proved temperamental in service and was soon relegated to training duties, where it served until 1927.

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".

Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-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 planes. 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 ...

Vickers Machine Gun
The Vickers machine gun or Vickers gun is a Water cooling, water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allies of World War I, Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every Britis ...

BMW IIIa
BMW IIIa was an inline six-cylinder SOHC valvetrain, water-cooled aircraft engine, the first-ever engine produced by Bayerische Flugzeugwerke AG, who, at the time, were exclusively an aircraft engine manufacturer. Its success laid the foundation for future BMW engine designs. It is best known as the powerplant of the Fokker D.VIIF, which outperformed any allied aircraft. Design and development On 20 May 1917, Rapp Motorenwerke (which later that year became BMW GmbH) registered the documentation for the construction design for the new engine, dubbed BMW III. Designed by Max Friz and based on the Rapp III engine, it was an SOHC in-line six-cylinder, just as the earlier Mercedes D.III was, which guaranteed optimum balance, therefore few, small vibrations. It was designed with a high (for the era) compression ratio of 6.4:1. The first design drawings were available in May, and on 17 September the engine was on the test rig. After a successful maiden flight for the IIIa in Decembe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avia BH-1
The Avia BH-1 was a two-seat sports plane built in Czechoslovakia in 1920. It was the first product of the Avia company, and it was originally designated BH-1 exp. The BH-1 was a low-wing braced monoplane of wooden construction, with Conventional landing gear, tailskid undercarriage. Power was provided by a Daimler Motoren Gesellschaft, Daimler engine, which proved inadequate to fly the aircraft with both seats occupied. Soon after its first flight, it was exhibited at the inaugural International Aviation Exhibition in Prague. Its reception there was so enthusiastic that Czechoslovak president Tomáš Masaryk awarded Avia a 100,000 Czechoslovak koruna, CSK development grant. The BH-1 was subsequently rebuilt with a Gnome Omega rotary engine and was finally able to fly with two people aboard. It was known as the BH-1 bis in this configuration, and in 1921 won the Czechoslovak national cross-country rally with an average speed of 125 km/h (78 mph) over the 860 km ( ...
