Aerotechnik WGM.21
The Aerotechnik WGM.21 is a quadrotor helicopter that was developed in the 1970s. Design and development The WGM.21 is an open cockpit quadrotor. Four rotors are mounted at the end of a four tubular supports arranged into a X shape. Cyclic and collective controls are mixed into a single control yoke. Pitch is controlled by foot pedals. A second model, the WGM.22, was developed with side-by-side configuration seating and an enclosed cockpit.

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 ...

Quadrotor Helicopter
A quadcopter or quadrotor is a type of helicopter with four rotors. Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern UAV or drone. The small size and low inertia of drones allows use of a particularly simple flight control system, which has greatly increased the practicality of the small quadrotor in this application. Design principles Each rotor produces both lift and torque about its center of rotation, as well as drag opposite to the vehicle's direction of flight. Quadcopters generally have two rotors spinning clockwise (CW) and two counterclockwise (CCW). Flight control is provided by independent variation of the speed and hence lift and torque of each rotor. Pitch and roll are controlled by varying the net centre of thrust, with yaw controlled by varying the net torque. Unlike conventional helicopters, quadcopters do not usually have cyclic pitch control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerotechnik
Evektor-Aerotechnik is a Czech aircraft manufacturer based in Kunovice, Czech Republic. The company produces range of light sport aircraft, training, advanced ultralight aircraft and electric aircraft. Evektor-Aerotechnik is also developing a 9–14 passenger, twin engine turboprop airplane, the EV-55 Outback. History Evektor-Aerotechnik is based at Kunovice Airport, a region known for its aircraft industry since 1936. Evektor-Aerotechnik dates back to 1970 when Aerotechnik was established as a producer of small general aviation airplanes. Its first aircraft were gyrocopters and motor gliders, later diversifying into the overhaul and maintenance of a range of Czech general aviation aircraft, including the Zlin aircraft family. The production of light sport aircraft and advanced ultralight aircraft started in 1996, starting with the P220UL Koala aircraft and followed by the EV-97 Eurostar (introduced in 1997) and SportStar. The SportStar became the first light sport aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Side-by-side Configuration
Tandem, or in tandem, is an arrangement in which a team of machines, animals or people are lined up one behind another, all facing in the same direction. The original use of the term in English was in ''tandem harness'', which is used for two or more draft horses, or other draft animals, harnessed in a single line one behind another, as opposed to a pair, harnessed side by side, or a team of several pairs. The tandem harness allows additional animals to provide pulling power for a vehicle designed for a single animal. The English word ''tandem'' derives from the Latin adverb , meaning ''at length'' or ''finally''. It is a word play, using the Latin phrase (referring to time, not position) for English "at length, lengthwise". Tandem bicycles are named for their tandem seating, a more common arrangement than side-by-side "sociable" seating. ''Tandem'' can also be used more generally to refer to any group of persons or objects working together, not necessarily in line. Automob ...

Hubschraubermuseum Bückeburg
The Hubschraubermuseum Bückeburg (Bückeburg Helicopter Museum) is located in the German town of Bückeburg, 30 miles (50 km) to the west of Hanover. The museum is the sole museum in Germany specialising in rotary-wing flight and one of few worldwide. The museum is dedicated to the history and technology of the helicopter. History Sergeant Major Werner Noltemeyer gathered parts, models, books and photographs of rotary-wing aircraft while he was training to become a helicopter pilot in the German Army Aviation Corps. In 1959 the German School of Army Aviation was established in Bückeburg. In the late 1960s, the city council of Bückeburg offered Noltemeyer an old timbered-framed building for use as a museum which opened in 1971. Due to a shortage of space an additional exhibition hall was added in 1980. The museum was further expanded with a glass addition in 2011. Hubschrauberzentrum e. V. The ''Hubschrauberzentrum e. V.''
