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 ...

Capacitor Discharge Ignition
Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine-powered aircraft, and some cars. It was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition (IDI) systems, making the ignition system more suitable for high engine speeds (for small engines, racing engines and rotary engines). The capacitive-discharge ignition uses capacitor discharge current to the coil to fire the spark plugs. History Nikola Tesla The history of the capacitor discharge ignition system can be traced back to the 1890s when it is believed that Nikola Tesla was the first to propose such an ignition system. In first filed February 17, 1897, Tesla writes 'Any suitable moving portion of the apparatus is caused to mechanically control the charging of a condenser and its discharge ...

Air-cooled Aircraft Piston Engines
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 ...

Windex 1200
The Radab Windex is a family of Swedish high-wing, single-seat aerobatic gliders and motor gliders that was designed by Sven Olof Ridder and produced initially by Radab and later by WindexAir AB as a kit for amateur construction.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 60. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X Design and development The initial design was the unpowered model 1100. This was followed by the present production 1200C motorglider. The project started off in 1980 as a hobby design between Sven-Olof Ridder and Harald Undén, who later founded Radab to produce the design. By 1983 they had developed the custom airfoil section and tested it in a wind tunnel. The first unpowered 1100 model flew in 1985, but the following year, as they geared up for kit production the factory burnt down, including all the fibreglass molds that they had built. Only two 1200 C aircraft kits had been produced before the molds wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chasle YC-100 Hirondelle
The Chasle YC-100 Hirondelle () is a French single seat microlight designed in the 1980s. Design and development Yves Chasle worked as an Aérospatiale stress engineer and independently designed several light aircraft, starting with the Chasle YC-12 Tourbillon. His YC-100 Hirondelle is a largely wooden framed and fabric covered single-seat sports aircraft of conventional pusher layout. It has a strut braced high wing of constant chord with styrofoam ribs. The fuselage of the Hirondelle is a slender, rectangular cross-sectioned beam with the pilot's seat upon it ahead of the wing leading edge. Behind the pilot a central structure supports the wing just above head level; on its trailing edge, one of several types of small piston engine, with power outputs typically around , drives a pusher propeller. The fin is broad and straight-tapered and the horizontal tail is attached to the fuselage underside. The Hirondelle has a short, fixed tricycle undercarriage. Its first flight was ...
