Cessna 177
The Cessna 177 Cardinal is a light single-engine, high-wing general aviation aircraft produced by Cessna. It was intended to replace the Cessna 172 Skyhawk. First announced in 1967, it was produced from 1968 to 1978.Christy, Joe: ''The Complete Guide to the Single-Engine Cessnas - 3rd Edition'', pages 54-61. TAB Books, 1979. Plane and Pilot: ''1978 Aircraft Directory'', page 25. Werner & Werner Corp Publishing, 1978. Development The Cessna 177 was designed in the mid-1960s when the engineers at Cessna were asked to create a "futuristic 1970s successor to the Cessna 172". The resulting aircraft featured newer technology such as a cantilever wing lacking the lift struts of previous models, and a new laminar flow airfoil. The 177 is the only production high-wing single-engined Cessna since the Cessna 190 & 195 series to have both fixed landing gear and a cantilever wing without strut bracing. In 1971, Cessna experimented with a "Quiet Cardinal" similar to the Beechcraft QU-22 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Fo ...

Jessica Dubroff
Jessica Whitney Dubroff (May 5, 1988 – April 11, 1996) was a seven-year-old American trainee pilot who died while attempting to become the youngest person to fly a light aircraft across the United States. On day two of her quest, the Cessna 177B Cardinal single-engine aircraft, piloted by her flight instructor, Joe Reid, crashed during a rainstorm immediately after takeoff from Cheyenne Regional Airport in Cheyenne, Wyoming, killing Dubroff, her 57-year-old father Lloyd Dubroff, and Reid. Although billed by the media as a pilot, Dubroff was not legally able to be a pilot because of her age. She did not possess a medical certificate or a student pilot certificate, since they require a minimum age of 16 or a pilot certificate that requires a minimum age of 17, according to U.S. Federal Aviation Administration (FAA) regulations. At the time of her trip, there was no record-keeping body that recognized any feats by underage pilots. Nevertheless, local, national, and internationa ...

Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/ Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alben Barkley
Alben William Barkley (; November 24, 1877 – April 30, 1956) was an American lawyer and politician from Kentucky who served in both houses of Congress and as the 35th vice president of the United States from 1949 to 1953 under President Harry S. Truman. After 1905, he was elected to local offices and in 1912 U.S. representative. In Congress he was a liberal Democrat, supporting President Woodrow Wilson's New Freedom domestic agenda and foreign policy. Endorsing Prohibition and denouncing parimutuel betting, Barkley narrowly lost the Democratic gubernatorial primary in 1923 to fellow representative J. Campbell Cantrill. In 1926, he unseated Republican senator Richard P. Ernst. In the Senate, he supported the New Deal approach to handling the Great Depression in the United States. Democrats chose him to succeed Senate Majority Leader Joseph Taylor Robinson upon Robinson's death in 1937. His 1938 re-election bid was an intense, bitter victory against Governor ...

Alben Truitt
Elbling is a variety of white grape (sp. ''Vitis vinifera'') which today is primarily grown in the upstream parts of the Mosel region in Germany and in Luxembourg, where the river is called Moselle. The variety has a long history, and used to cover much of Germany's vineyards from medieval times and was that country's most cultivated variety until the early 20th century, but has been in decline ever since. As of 2006, there were of Elbling vineyards in Germany, which made it the country's 23rd most grown variety of grape. Of that vineyard surface, 575 ha or 98.6% was found in the Mosel regionGerman Wine Institute: German Wine Statistics 2007-2008 In the same year, there were of Elbling grown in ...

Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and ...

Constant-speed Propeller
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed ( RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is ...

Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the r ...
