A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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".

Waco Custom Cabin Series
The Waco Custom Cabins were a series of up-market single-engined four-to-five-seat cabin sesquiplanes of the late 1930s produced by the Waco Aircraft Company of the United States. "Custom Cabin" was Waco's own description of the aircraft which despite minor differences, were all fabric-covered biplanes. Design Nearly all of the Waco Custom Cabins were powered by radial engines (there being one factory-built exception, the MGC-8) and the purchaser could specify almost any commercially available engine and Waco would build an aircraft powered by it, hence the profusion of designations, as the first letter indicates the engine installed. Some models were offered in case someone wanted a specific engine but not all were built. Fuselage structure was typical for the period, being welded steel tubing with light wood strips to fair the shape in. The wings were made of spruce with two spars each, having ailerons on only the upper wings, mounted on a false spar. Split flaps were installed ...

1930s Aircraft Piston Engines
Year 193 ( CXCIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

Wright R-760
The Wright R-760 Whirlwind was a series of seven-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of 756 in³ (12.4 L) and power ratings of 225-350 hp (168-261 kW). Design and development Wright introduced the J-6 Whirlwind family in 1928 to replace the nine-cylinder R-790 series. The J-6 family included varieties with five, seven, and nine cylinders. The seven-cylinder version was originally known as the J-6 Whirlwind Seven, or J-6-7 for short. The U.S. government designated it as the R-760; Wright later adopted this and dropped the J-6 nomenclature. Like all the members of the J-6 Whirlwind family, the R-760 had larger cylinders than the R-790. The piston stroke of 5.5 in (14.0 cm) was unchanged, but the cylinder bore was expanded to 5.0 in (12.7 cm) from the R-790's bore of 4.5 in (11.4 cm). While the R-790 was naturally aspirated, the ...

Piaggio Stella P
Piaggio Group () is an Italian motor vehicle manufacturer, which produces a range of two-wheeled motor vehicles and compact commercial vehicles under five brands: Piaggio, Vespa, Aprilia, Moto Guzzi and Derbi. Its corporate headquarters are located in Pontedera, Italy. The company was founded by Rinaldo Piaggio in 1884, initially producing locomotives and railway carriages. Piaggio Group's subsidiaries employ a total of 7,053 employees and produced a total of 519,700 vehicles in 2014. The manufacturer has six research-and-development centres and operates in over 50 countries. History In 1882, Enrico Piaggio purchased land in Sestri Ponente (Genoa) to set up a timber yard. Two years later, in 1884, his 20-year-old son, Rinaldo Piaggio (1864–1938), founded Piaggio & C. The company initially built locomotives and railway carriages. In 1917, towards the end of World War I, Rinaldo Piaggio turned to the military sector: The company started to produce MAS anti-submarine moto ...

Bristol Neptune
The Bristol Neptune was a seven-cylinder air-cooled radial engine developed in 1930. It had the same size cylinders as the earlier Mercury and Titan engines, 5.75 in (146 mm) x 6.5 in (165 mm) which gave a displacement of 1,182 cu in (19.3 L) and produced a maximum of 320 horsepower (239 kW). The Neptune was effectively a seven-cylinder version of the Titan.Lumsden 2003, p.103.

Avia Rk
AVIA () is a Soviet/Russian experimental pop band formed in Leningrad in 1986. AVIA released four studio albums and led the first wave of the Soviet bands which made their breakthrough in the West in the late 1980s. Band history AVIA was formed in September 1985 by the ex-members of Strannye Igry, multi-instrumentalists Nikolai Gusev, Alexey Rakhov and drummer Alexander Kondrashkin who were joined by Anton Adasinsky (guitars, vocals), saxophonists Elena Bobretsova and Alexey Merkushev, and performance artist Marat Timergazov who, supported by the ever growing cast of dancers and gymnasts created a peculiar mass pantomime comprising elements of 1920s constructivism, sports parades and the early Soviet visual culture clichés. Equally eclectic was the band's style, a mix of new wave rock, quasi-classical marches and synthpop. In 1987 AVIA received the special Press Award at the Rock Panorama musical festival and featured in Alexey Uchitel's film "Rock". The group's first album, ...

Armstrong Siddeley Cheetah
The Armstrong Siddeley Cheetah is a seven-cylinder British air-cooled aircraft radial engine of 834 cu in (13.65 L) Engine displacement, capacity introduced in 1935 and produced until 1948. Early variants of the Cheetah were initially known as the Lynx Major.Lumsden 2003, p.74. The Cheetah was used to power many British Trainer (aircraft), trainer aircraft during World War II including the Avro Anson and Airspeed Oxford. Design and development The Cheetah was developed from the earlier Lynx using the increased Bore (engine), bore cylinders from the Armstrong Siddeley Panther but the engine retained the Stroke (engine), stroke of the Lynx. Initially only direct-drive variants were produced with later engines being made available with propeller reduction gear of various Gear ratio, ratios. Superchargers were also available for later variants, both geared and directly driven by the crankshaft. The basic design of the Cheetah remained unchanged from its introduction in 1935 to th ...

Octane Rating
An octane rating, or octane number, is a standard measure of a liquid fuel, fuel's ability to withstand Compression ratio, compression in an internal combustion engine without causing engine knocking. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates the resistance to detonating under pressure without a spark. Whether a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression Petrol engine, gasoline engines, which may yield higher power for these engines. The added power in such cases comes from the way the engine is designed to compress the air/fuel mixture, and not directly from the rating of the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are idea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
