Mitchell U-2 Superwing
The Mitchell U-2 Superwing is an American tailless ultralight aircraft that was designed by Don Mitchell for amateur construction.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page E-259. Cybair Limited Publishing, 2001. Design and development Although the aircraft was designed before the US FAR 103 Ultralight Vehicles rules came into force, the U-2 Superwing complies with them anyway (including the category's maximum empty weight of ). The aircraft has a standard empty weight of . It features a cantilever mid-wing, a single-seat enclosed cockpit, tricycle landing gear and a single engine in pusher configuration. The U-2 is a development of the high-wing B-10. The aircraft fuselage is made from welded steel tube, while the wing is of wood and foam, with doped aircraft fabric covering. Its span wing employs a modified Wortmann FX05-191 airfoil. The flight controls are unconventional; pitch and roll are controlled by elevons and yaw is controlled by ...

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".

Aircraft Dope
Aircraft dope is a plasticised lacquer that is applied to fabric-covered aircraft. It tightens and stiffens fabric stretched over airframes, which renders them airtight and weatherproof, increasing their durability and lifespan.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 170. Aviation Supplies & Academics, 1997. The technique has been commonly applied to both full-size and flying models of aircraft. Attributes Doping techniques have been employed in aircraft construction since the dawn of heavier-than-air flight; the fabric of the ground-breaking Wright Flyer had benefitted from doping, as did many of the aircraft that soon followed. Without the application of dope, fabric coverings lacked durability while being highly flammable, both factors rendering them far less viable. By the 1910s, a wide variety of doping agents had entered widespread use while entirely original formulas were being regularly introduced in the industry. Typical doping agents in ...

1970s United States Ultralight Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 '' Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

Archive
An archive is an accumulation of historical records or materials – in any medium – or the physical facility in which they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative, or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultralight Aircraft (United States)
Ultralight aircraft in the United States are much smaller and lighter than ultralight aircraft as defined by all other countries. In the United States, ultralights are described as "ultralight vehicles" and not as aircraft. They are not required to be registered, nor is the pilot required to have a pilot's certificate. United States definition of "ultralight" Regulation of ultralight aircraft in the United States is covered by the Code of Federal Regulations, Title 14 (Federal Aviation Regulations), Part 103, or ''14 CFR Part 103'', which defines an "ultralight" as a vehicle that: * has only one seat * Is used only for recreational or sport flying * Does not have a U.S. or foreign airworthiness certificate * If unpowered, weighs less than 155 pounds * If powered: ** Weighs less than 254 pounds (115 kg) empty weight, excluding floats and safety devices ** Has a maximum fuel capacity of 5 U.S. gallons (19 L) ** Does not exceed 55 knots (102 km/h; 63 mph) c ...

Ultralight Aviation
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aériane Swift
The Aériane Swift is a lightweight (48 kg) foot-launched tailless sailplane whose rigid wings have a span of 40 feet. The Swift has been succeeded by the "Swift'Lite". Although designed in California, Swift aircraft are now manufactured by Aériane, a European firm based in Gembloux, Belgium. Aériane first manufactured the Swift under licence, but the firm is now the sole manufacturer. Design & development The Swift (an acronym for 'Swept Wing with Inboard Flap for Trim') was originally conceived as a rigid hang glider with sailplane-like performance. Bright Star Gliders had developed the 1989 U.S. National Hang Gliding Championship winning Odyssey prototype. Meanwhile Professor Ilan Kroo and a group of graduate students at Stanford University had developed the Stanford SWIFT design project. When Brian Porter of Bright Star met Stanford student Steve Morris, the projects merged. Bright Star constructed the revised SWIFT and its first flight took place in December 1989.Il ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft 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 (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), 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 after end. Often rudders are shaped so as to minimize Drag (physics), 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 be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Tip
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: * Squared-off * Aluminium tube bow * Rounded * Hoerner style * Winglets * Drooped tips * Raked wingtips * Tip tanks * Sails * Fences * End plates Winglets have become popular additions to high speed aircraft to increase fuel efficiency by reducing drag from wingtip vortices. In lower speed aircraft, the effect of the wingtip shape is less apparent, with only a marginal performance difference between round, square, and Hoerner style tips The slowest speed aircraft, STOL aircraft, may use wingtips to shape airflow for controllability at low airspeeds. Wing tips are also an expression of aircraft design style, so their shape may be influenced by marketing considerations as well as by aerodynamic requirements. Wing tips are ...
