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 ...

Aerocomp VM-1 Esqual
The Aerocomp VM-1 Esqual is a Swedish ultralight aircraft, produced by Arsi AB (formerly Aerocomp AB) of Alingsås. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 17.

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

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. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Electronic Fuel Injection
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine. In a manifold-injected engine, the fuel is injected into the intake manifold, where it begins forming a combustible air-fuel mixture with the air. As soon as the intake valve opens, the piston starts sucking in the still forming mixture. Usually, this mixture is relatively homogeneous, and, at least in production engines for passenger cars, approximately stoichiometric; this means that there is an even distribution of fuel and air across the combustion chamber, and enough, but not more air present than what is required for the fuel's complete combustion. The injection timing and measuring of the fuel amount can be controlled either mechanically (by a fuel distributor), or electronically (by an engine control unit). Since the 1970s and 1980s, manifol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat-4
A flat-four engine, also known as a horizontally opposed-four 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 an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 compliance ... [...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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
