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 ...

Pratt & Whitney Canada PT6A
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964 and has been continuously updated since. It consists of two basic sections: a gas generator with accessory gearbox and a free power turbine with reduction gearbox, and is often seemingly mounted backwards in an aircraft in so far as the intake is at the rear and the exhaust at the front. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, had logged 400 million flight hours from 1963 to 2016. It is known for its reliability with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A covers the power range between while the PT6B/C are turboshaft variants for he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970s United States Agricultural 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.

Air Tractor Aircraft
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in E ...

Air Tractor AT-802
The Air Tractor AT-802 is an American agricultural aircraft that may also be adapted into fire-fighting or armed versions. It first flew in the United States in October 1990 and is manufactured by Air Tractor The AT-802 carries a chemical hopper between the engine firewall and the cockpit. In the U.S., it is considered a Type III SEAT, or Single Engine Air Tanker. Development In its standard configuration, the aircraft utilizes conventional landing gear (two main wheels and a tail wheel). However, a number of aircraft have been converted to the Fire Boss aerial firefighting configuration, which utilizes Wipaire 10000 amphibious floats, so that it can land on a traditional runway or on water. The Fire Boss can scoop water from a lake or river for use on a fire. In addition to the AT-802 Fire Boss Factsheet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Tractor AT-501
The Air Tractor AT-500 is a family of agricultural aircraft that first flew in the United States on 25 April 1986, manufactured by Air Tractor Inc. Of monoplane low-wing, taildragger configuration, they carry a chemical hopper between the engine firewall and the cockpit. Compared with their predecessor, the AT-500 family mostly feature a wingspan increased to 50 ft (15.2 m), and an additional fuselage stretch of 22 in (56 cm), allowing for a larger chemical hopper. Almost all variants offer a widened "buddy" seat or a tandem seat for a passenger, observer, or loader; trainer aircraft with full dual controls have also been offered. From 2011 through 2018, the AT-502B was the world's top-selling agricultural aircraft with 388 deliveries, while the combined AT-500 line (AT-502A, -502B, and -504) was among the world's most popular fixed wing general aviation single-turboprop aircraft families, with 470 delivered—a total exceeded only by the Pilatus PC-12 and the Cessna 20 ...

PZL-3S
The Ivchenko AI-26 is a seven-cylinder air-cooled radial engine used in early Soviet helicopters and later used in light utility aircraft. Design and development The AI-26 engine was designed by A.G Ivchenko in 1945 with the early designation M-26, later the designation was changed to AI-26. Like the Shvetsov ASh-21 which is basically one bank of cylinders from the Shvetsov ASh-82, the AI-26 was also influenced by the ASh-82. The AI-26 retained the bore, stroke and displacement of the ASh-21 while incorporating new features peculiar to its role. This similarity allowed the AI-26 to use the same production jigs as the ASh-21 and ASh-82 which reduced costs and simplified production. The engine was envisioned as a helicopter engine, but the early test models lacked the necessary equipment to facilitate this role, such as an auxiliary cooling fan, reduction gears and clutch. The GR suffix means ''"Gelikopter"'', or helicopter. Engine testing was completed by early 1946 and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...
