Etrich Sport-Taube
The Etrich Sport-Taube was a one-off, single engine, one seat monoplane, built in Czechoslovakia in 1929. Design and development The Sport-Taube was a plane built and designed by Igo Etrich, the famous builder of the Etrich Taube. It was originally intended as a ''Volksflugzeug'', a low-cost airplane. However, it faced difficulties regarding production in series and the project was given up. After World War I, Etrich moved to Trautenau, now Trutnov, in the newly founded Czechoslovakia. He built the ''Sport-Taube'', a closed-cockpit monoplane, in the same factory where he built textile machinery. The original plane is now displayed suspended from the roof at the National Technical Museum (Prague), National Technical Museum in Prague, Czech Republic. The Sport-Taube was powered by a engine. Operational history Although the Sport-Taube was intended to be commercialized as a private aircraft, with its engine it was deemed to be faster than the planes of the Czechoslovak Air Force ...

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".

High-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 an ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Smuggling
Smuggling is the illegal transportation of objects, substances, information or people, such as out of a house or buildings, into a prison, or across an international border, in violation of applicable laws or other regulations. More broadly, social scientists define smuggling as the purposeful movement across a border in contravention to the relevant legal frameworks. There are various motivations to smuggle. These include the participation in illegal trade, such as in the drug trade, illegal weapons trade, prostitution, human trafficking, kidnapping, heists, chop shops, illegal immigration or illegal emigration, tax evasion, import restrictions, export restrictions, providing contraband to prison inmates, or the theft of the items being smuggled. Smuggling is a common theme in literature, from Bizet's opera ''Carmen'' to the James Bond spy books (and later films) '' Diamonds Are Forever'' and '' Goldfinger''.

Czechoslovak Air Force
The Czechoslovak Air Force (''Československé letectvo'') or the Czechoslovak Army Air Force (''Československé vojenské letectvo'') was the air force branch of the Czechoslovak Army formed in October 1918. The armed forces of Czechoslovakia ceased to exist on 31 December 1992. By the end of the year, all aircraft of the Czechoslovak Air Force were divided between the Czech Air Force and the Slovak Air Force. Organization On 30 October 1918, the establishment of Aviation Corps (''Letecký sbor'') marked the beginning of the Czechoslovak Air Force. Under the First Republic, the air force was an integral service of the Czechoslovak army. During peacetime, the army aviation was a subordinate agency of the Ministry of National Defence within its 3rd Department of Aviation (''III. odbor (letecký) Ministerstva národní obrany'') under the command of divisional general Jaroslav Fajfr (as of October 1938). It was anticipated that individual squadrons and flights would be att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Textile Machinery
Textile manufacturing or textile engineering is a major Textile industry, industry. It is largely based on the conversion of fibre into yarn, then yarn into fabric. These are then Dyeing, dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing, Linens, household items, upholstery and various industrial products. Different types of fibres are used to produce yarn. Cotton remains the most widely used and common natural fiber making up 90% of all-natural fibers used in the textile industry. People often use cotton clothing and accessories because of comfort, not limited to different weathers. There are many variable processes available at the Spinning (textiles), spinning and fabric-forming stages coupled with the complexities of the Finishing (textiles), finishing and colouration processes to the production of a wide range of products. History Textile manufacturing in the modern era is an evolved form of the art and craft industries. Unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
