WikiProject Aircraft
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".

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r⋅min−1) is a unit of rotational speed (or rotational frequency) for rotating machines. One revolution per minute is equivalent to hertz. Standards ISO 80000-3:2019 defines a physical quantity called ''rotation'' (or ''number of revolutions''), dimensionless, whose instantaneous rate of change is called ''rotational frequency'' (or ''rate of rotation''), with units of reciprocal seconds (s−1). A related but distinct quantity for describing rotation is ''angular frequency'' (or ''angular speed'', the magnitude of angular velocity), for which the SI unit is the radian per second (rad/s). Although they have the same dimensions (reciprocal time) and base unit (s−1), the hertz (Hz) and radians per second (rad/s) are special names used to express two different but proportional ISQ quantities: frequency and angular frequency, respectively. The conversions between a frequency and an angular frequency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-cooled
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps. Air-cooled engines are widely seen in applications where weight or simplicity is the primary goal. Their simplicity makes them suited for uses in small applications like chainsaws and lawn mowers, as well as small generators and similar roles. These qualities also make them highly suitable for aviation use, where they are widely used in general aviation aircraft and as auxiliary power units on larger aircraft. Their simplicity, in particular, also makes them common on motorcycles. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fluid ...

Electronic Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction create ...

Flat-4
A flat-four engine, also known as a horizontally opposed-four engine or boxer 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 a straight-four engine. There is a minor, secondary unbalanced rotational torque pulse in the plane of the pistons, when a piston pair at one end of the engine is at TDC and the other pair at BDC. The TDC pair creates a torque greater than the BDC pair, so the net unbalanced torque pulse is the difference. The difference in TDC vs BDC inertial forces is explained in the Engine balance section. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trixy G 4-2 R
The Trixy G 4-2 R ("Gyro For Two powered by Rotax") is an Austrian autogyro, designed and produced by Trixy Aviation Products of Dornbirn. The aircraft was introduced at the Aero show held in Friedrichshafen in 2011 and when it was available it was supplied as a complete ready-to-fly-aircraft.Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 187.

Sonex Aircraft Onex
The Onex (pronounced "One-X" ) is an American single-seat, low-wing aircraft first flown on 27 January 2011 and currently being produced by Sonex Aircraft as a kit for amateur construction.Tacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015-16'', page 126. Flying Pages Europe SARL, 2015. Design and development The Onex was designed to be economical, have aerobatic capabilities and folding wings, allowing storage in a standard high by wide residential garage. The aircraft has been designed to standard light aircraft FAR-23 static load requirements with the wings supporting more than 10,000 pounds in sandbags during the tests. Intended for the US experimental home-built and light-sport aircraft categories, in 2012 the company estimated the total price to purchase and build the aircraft to be around US$25,299, making it the least expensive of their kits. The FAA's National Kit Evaluation Team has approved construction checklists demonstrating complianc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silence Twister
The Silence Twister is a German ultralight designed by Silence Aircraft for amateur construction, either from plans or kits. The prototype first flew on 30 September 2000. Design and development The Twister is a single-seat low-wing monoplane with elliptical wings and tailplane. It has a retractable conventional landing gear with a fixed tailwheel. The design drew inspiration from the Supermarine Spitfire, and the shapes of the Twister's wings, fin and tailplane all recall the famous World War II fighter. Designed to take engines up to , the prototype was fitted with a single-rotor MidWest Wankel engine. This compact rotary motor allowed a sleek engine cowling, but the engine was rejected and production aircraft use Jabiru 2200 or ULPower UL260i engines. An electric aircraft version was under development in 2010. Propeller The Twister prototype was fitted with Silence Aircraft's own automatic variable-pitch propeller called the " VProp". The LAA have yet to allow the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reality Escapade UK
The Just Escapade is a single-engine, high-wing light aircraft, seating two in side-by-side configuration. It was jointly developed in the United States and the United Kingdom in the early 2000s and by 2010 some 145 Escapades and its "bush plane" variant, the Highlander, had been built and many more kits sold. Design and development The Escapade design can be traced back to that of the Avid Flyer, via the Denney Kitfox and Reality Easy Raider, marrying the Easy Raider's wing to a stretched Kitfox Lite fuselage. The key differences between the two types are the Escapade's side-by-side seating in a widened cabin, dual controls, and the option of a tricycle undercarriage It was developed jointly in the United States and United Kingdom by Just Aircraft and Reality Aircraft respectively, the American prototype flying in February 2003, four months before its British counterpart. These prototypes differed to fit into local classifications. The Escapade has a Chromoloy steel frame a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
