Fedorov Me7 Mechta
The Aviastroitel AC-4 Russia is a Russian mid-wing, single-seat Glider (sailplane), glider designed by Vladimir Egorovich Fedorov and produced by Aircraft Cooperative Mechta, which became Aviastroitel, now Glider Air Craft. The aircraft is sometimes referred to as the Federov AC-4 Russia, Mechta AC-4, Fedorov Me7 Mechta, Kenilworth Me7, AS+ Ltd AC-4 or Aircraft Cooperative Mechta AC-4 Russia. It is currently marketed as the Glider Air Craft Solo AC-4.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 54. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X Design and development The aircraft started out in 1989 as Fedorov's "Dream" project for the OSTIV World Class Sailplane 1993 design contest. It went through several design prototypes, named Mechta I, Mechta II and Russia I and II. The Russia II was the version submitted to the competition. The bid involved forming a new concern, the ''Aircraft Cooperative Mechta'' and building three hand-ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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".

Club Class
Competition classes in gliding, as in other sports, mainly exist to ensure fairness in competition. However the classes have not been targeted at fostering technological development as in other sports. Instead classes have arisen because of: * the popularity of certain types of glider * attempts to contain the cost of access to the sport * the need to establish a stable environment for investment decisions by both manufacturers and competitors. The FAI Gliding Commission (IGC) is the sporting body overseeing air sports at the international level so that essentially the same classes and class definitions are followed in all countries. FAI Competition Classes Seven glider classes are currently recognised by the FAI and are eligible for European and World Championships: * Open Class, places no restrictions except a limit of 850 kg to the maximum all-up mass, may be one- or two-seater e.g. JS-1C, Lange Antares 23E, Quintus, ASW 22, ASH 30, LAK-20. * Standard Class, restri ...

Taildragger
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudder and tailwheel to move together. Before aircraft commonly used tailwheels, many aircraft (like ...

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental aircraft, Experimental under Federal Aviation Administration, FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on m ...

Type Certificate
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design (''type design''). Certification confirms that the aircraft of a new type intended for serial production is in compliance with applicable airworthiness requirements established by the national air law. For up to three seats, Airworthiness certificate#Special Airworthiness Certificate, primary category aircraft certification costs around US$1 million, US$25 million for a general aviation aircraft and hundreds of millions of dollars for a commercial aircraft; certification delays can cost millions of dollars and can decide a program's profitability. Authority A type certificate (TC) is issued to signify the airworthiness of the approved design or "type" of an aircraft to be manufactured. The TC is issued by a regulatory authority, and once issued, the design cannot be changed unless at least part of the process for certification is repeated to cover the changes ...

Ballistic Recovery Systems
Ballistic Recovery Systems, Inc., doing business as BRS Aerospace (and commonly referred to as simply BRS), is a manufacturer of aircraft ballistic parachutes. The company was formed in 1980 by Boris Popov of Saint Paul, Minnesota, after he survived a fall in a partially collapsed hang glider in 1975. As a result, Popov invented a parachute system that could lower an entire light aircraft to the ground in the event of loss of control, failure of the aircraft structure, or other in-flight emergencies. Popov was granted a U.S. patent on 26 August 1986 for the so-called Ballistic Recovery System (BRS) - patent US 4607814 A. The company has two divisions: BRS Aviation and BRS Defense. History BRS was founded in 1980 and introduced its first parachute model two years later in 1982, with focus on the ultralight aircraft market. The company recorded its first successful aircraft and crew recovery in 1983: Jay Tipton of Colorado. In 1998, BRS collaborated with Duluth, Minnesota-bas ...

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringent emissions regulation, two-stroke engines have ...
