Volmer VJ-22 Sportsman
The Volmer VJ-22 Sportsman is an American homebuilt amphibious aircraft. The Sportsman is a two-seat high-winged monoplane of wood and fabric construction, with over 100 built by 1993. Development and design Volmer Jensen, a successful designer of sailplanes, designed the two-seat amphibious VJ-22 in 1957.McCarrel, Bill.The Volmer VJ-22 Sportsman. ''The Seaplane Pilots Association''. 14 August 2008. Retrieved 13 March 2010. The new aircraft, at first called the ''Chubasco'', made its first flight on 22 December 1958.Taylor 1976, p.541. The VJ-22 is a high-winged monoplane, using the wings from an Aeronca Champion or Chief, with a new flying boat hull of mahogany plywood, waterproofed with fiberglass cloth. The aircraft's single engine, normally a pusher of between 85 hp (63 kW) and 100 hp (75 kW), is mounted on pylons above the wing centre section. The engine can also be mounted in tractor configuration and engines of up to 135 hp (101 kW) have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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".

Tractor Configuration
In aviation, the term tractor configuration refers to an aircraft constructed in the standard configuration with its engine mounted with the propeller in front of it so that the aircraft is "pulled" through the air. Oppositely, the pusher configuration places the airscrew behind and propels the aircraft forward. Through common usage, the word "propeller" has come to mean any airscrew, whether it actually propels or pulls the plane. In the early years of powered aviation both tractor and pusher designs were common. However, by the midpoint of the First World War, interest in pushers declined and the tractor configuration dominated. Today, propeller-driven aircraft are assumed to be tractors unless it is stated otherwise. Origins The first airplane to have a "tractor" configuration was the Goupy No.2 (first flight on 11 March 1909) designed by Mario Calderara and financed by Ambroise Goupy at the French firm Blériot Aéronautique. When it was constructed, it was the fast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), 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 (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1950s United States Sport Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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.

Thurston Teal
The Thurston Teal is a family of two- and four-seat all-aluminium amphibious aircraft designed by David Thurston in the United States and first flown in 1968. A total of 38 Teals were manufactured. Development The Teal design features a high wing with tip floats for lateral stability. The horizontally opposed engine is mounted tractor fashion in a strut-supported pylon above the wing root. The T-tail includes a water rudder and tailwheel that swings up against the bottom of the rudder. Conventional undercarriage includes flat, spring-steel main undercarriage legs that rotate aft for water landings. The aircraft was designed to be very rugged and simple, with manually operated flaps and landing gear. The conventional (taildragger) configuration was chosen to make beaching the aircraft more practical, with no nosewheel to be damaged when running up on shore. The aircraft may be left floating with the mainwheels extended, to act as fenders to the bottom. Pilot and passenger sit sid ...

Taylor Coot
__NOTOC__ The Taylor Coot is a two-seat homebuilt amphibious aircraft designed by Moulton Taylor, famous for his flying car designs. When a market for the Aerocar did not emerge, Taylor turned to more conventional designs. The Coot was nonetheless somewhat unusual for its low wing, a feature uncommon on most seaplanes and flying boats, which conventionally strive to keep their wings as far away from the water as possible. Instead, Taylor designed the Coot's wing roots to act as sponsons to stabilise the craft in the water. The arrangement allowed him to do away with the weight and drag penalties imposed by wingtip floats, and additionally gain ground effect benefits during takeoff. First flown in 1969, the Coot proved very popular with homebuilders, with an estimated 70 aircraft completed by 2007. The wings and elevator surfaces of the Taylor Coot can be folded for transport and storage. With wings folded the aircraft is wide. Some builders have equipped their aircraft with a ...

Anderson Kingfisher
__NOTOC__ The Anderson EA-1 Kingfisher is a US two-seat amphibious aircraft designed and marketed for homebuilding. It was the work of Earl William Anderson, a Pan Am airline captain, who flew the prototype on 24 April 1969. By 1978, 200 sets of kits for the plane had been sold, and 100 Kingfishers were reported to be under construction. The aircraft is a shoulder-wing monoplane with a flying boat hull and outrigger pontoons. On land, it uses retractable tailwheel undercarriage. The single engine with a tractor propeller is mounted in a nacelle above the wing. Some builders utilize the wings from a Piper Cub The Piper J-3 Cub is an American light aircraft that was built between 1938 and 1947 by Piper Aircraft. The aircraft has a simple, lightweight design which gives it good low-speed handling properties and short-field performance. The Cub is Pi ... rather than making their own.

Flat-four
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
