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 ...

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

Lookout Mountain
Lookout Mountain is a mountain ridge located at the northwest corner of the U.S. state of Georgia, the northeast corner of Alabama, and along the southeastern Tennessee state line in Chattanooga. Lookout Mountain was the scene of the 18th-century "Last Battle of the Cherokees" in this area during the Nickajack Expedition. On November 24, 1863, during the American Civil War, the Battle of Lookout Mountain took place here. Name The name appears on maps as early as Mathew Carey's 1795 "Map of The Tennassee Government." Geography Northern and eastern slopes and summit Lookout Mountain and Sand Mountain (to the southwest) make up a large portion of the southernmost end of the Cumberland Plateau. The area was lifted from an ancient sea, and worn down by erosion for millions of years. The summit, called "High Point", is located just east of Thompsonville in Walker County, Georgia, with an elevation of above sea level. The foothills of the mountain extend into Chickamauga and Chat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1990s United States Ultralight Aircraft
Year 199 ( CXCIX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was sometimes known as year 952 ''Ab urbe condita''. The denomination 199 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 * Mesopotamia is partitioned into two Roman provinces divided by the Euphrates, Mesopotamia and Osroene. * Emperor Septimius Severus lays siege to the city-state Hatra in Central-Mesopotamia, but fails to capture the city despite breaching the walls. * Two new legions, I Parthica and III Parthica, are formed as a permanent garrison.

Skycycle X-2
The Skycycle X-2 was a steam-powered rocket owned by Evel Knievel and flown during his Snake River Canyon jump in Idaho in 1974. An earlier prototype was designed, named the Skycycle X-1, by Doug Malewicki and retired U.S. Navy engineer Robert Truax. It was tested in November 1973 and dove in the Snake River. The Skycycle X-2 was designed by Truax, and ridden by Knievel in his attempt to jump the Snake River approximately west of Shoshone Falls near the city of Twin Falls, Idaho, on September 8, 1974. The parachute deployed during the launch, causing the stunt to fail. A later analysis showed that a design flaw in a mechanical parachute retention cover, which did not properly take base drag into account, caused the premature parachute deployment. Following the failed jump, Truax blamed Knievel for the failure and vice versa. Later, Truax accepted full responsibility for the failure. The jump Although the parachute deployed early, the aerial photographs show the X-2 cleared t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piper PA-8 Skycycle
__NOTOC__ The Piper PA-8 Skycycle was a 1940s American single-seat light aircraft designed and built by Piper Aircraft at their Lock Haven, Pennsylvania plant. Towards the end of 1944 Piper announced a number of aircraft it intended to build after the war. One of these was the PWA-8 (Post War Airplane 8). An aerodynamic test aircraft was built with the name Cub Cycle and it first flew on 27 August 1944 with a small two–cylinder Franklin engine. The Franklin engine was replaced by a four–cylinder Continental A-40-3 of ; the aircraft first flew with the Continental engine on 12 September 1944. The Skycycle was a fabric-covered mid-wing single-engined single-seat monoplane with a tailwheel landing gear. The fuselage was produced using an auxiliary belly fuel tank as used on the F4U Corsair. The Cub Cycle was scrapped and a similar but new aircraft was built with the name Skycycle, which first flew on 29 January 1945 using the same Continental engine as the Cub Cycle. The aircraft ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, 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 (automotive), 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 Scotland, Scottish engineer Dugald Clerk, who pa ...
