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 ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Aircraft First Flown In 1975
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Birdman Aircraft
Birdman Aircraft was a U.S. aircraft manufacturer that marketed the Birdman TL-1 ultralight in the 1970s and early 1980s, at the time, the lightest aircraft to have ever flown. The firm was based at the Daytona Beach International Airport in Florida Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to ....

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).

Zenair Zipper
The Zenair Zipper is a Canadian ultralight high-wing, single seat aircraft that was designed by Chris Heintz and produced by Zenair. The Zipper is a highly innovative design that strongly emphasizes portability over speed or carrying capacity.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page E-46. Cybair Limited Publishing, 2001. Development The Zipper was designed in the early 1980s by established Canadian aircraft designer Chris Heintz and put into production by his company Zenair, of Midland, Ontario. Heintz's motivation for the Zipper was the ultralight aviation boom that was occurring in Canada at that time and the introduction of new aviation regulations by Transport Canada legally permitting the operation of ultralights. The Zipper incorporates many unique features, all aimed at making the aircraft more portable. This focus was due to the nature of operations in the early days of the ultralight popularity. Aircraft were not flown great distances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chotia Weedhopper
The Weedhopper is an American high-wing, tractor configuration, tricycle gear, two-axis control ultralight aircraft originally developed by John Chotia during the height of the 1970s ultralight boom and introduced in 1977. When it was in production the aircraft was sold as a kit for amateur construction and could be assembled in 25-30 man-hours.Downey, Julia: ''2008 Kit Aircraft Directory'', Kitplanes, Volume 24, Number 12, December 2007, page 80.

Beaujon Enduro
The Beaujon Enduro is a single-seat, American high-wing, pusher configuration ultralight aircraft. The Enduro was introduced in 1978 and remains available as plans from Beaujon Aircraft of Ardmore, Oklahoma.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page B-8. Cybair Limited Publishing, 2001. Development The Enduro is an early ultralight design that was first developed before the United States ultralight category and its FAR 103 ''Ultralight Vehicles'' rules were finalized, but it fits into the requirements including the category's maximum empty weight. With the originally specified Briggs & Stratton 401417, four-stroke, 656 cc, lawn mower powerplant the aircraft has an empty weight of . The engine burns only per hour giving an endurance of 5 hours on the specified of fuel, hence the aircraft's name. Reviewer Andre Cliche says of Beaujon's designs that they are "beautifully simple".

ISSN 0891-1851 Avid Aircraft went out of business in November 2003 and the aircraft kits are no longer available. Development The Champion was created by scaling down the Avid Mark IV and narrowing the wider fuselage into a single seat design intended to comply with the US FAR 103 ''Ultralight Vehicles'' category. The design is a conventional tractor configuration, featuring tube and aircraft fabric construction. The main landing gear is bungee suspended and includes a steerable tailwheel. Like other Avid designs, the wing has an under-cambered airfoil, Junkers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerosport Rail
The Aerosport Rail is an American minimalist ultralight aircraft, designed by Harris Woods and built by Aerosport Inc. The aircraft was first flown on 14 November 1970. Design and development The Rail is little more than a 2 by 5 inch squared aluminium tube (rail) with all-metal wings and a T-tail. The pilot sits on the tube, just ahead of and above the wings. Two small two-cycle engines derated to are mounted on struts behind the seat on either side of centerline, driving pusher propellers. Individual fiberglass fuel tanks are mounted in front of each engine. About 175 sets of plans were sold between 1970 and 1977. The follow-on design, the Aerosport Quail uses the Rail's wing design for an enclosed tractor configuration homebuilt aircraft.
