Aero L-39 Skyfox
The Aero L-39 Skyfox, also known as Aero L-39NG ("Next Generation"), is a turbofan-powered military Trainer aircraft, trainer and light combat aircraft developed and produced by the Czech aircraft manufacturer Aero Vodochody. It is a successor of the Cold War era Aero L-39 Albatros. During July 2014, Aero Vodochody announced the launch of the L-39NG programme. By April 2015, the company revealed a partnership between itself, Draken International and Williams International to jointly work on the project — the latter provides its Williams FJ44, FJ44-4M turbofan engine for the aircraft, while Draken will be responsible for the type on the North American market, as well as operate its own fleet. On 14 September 2015, the maiden flight of the L-39NG technology demonstrator (L-39CW) was performed. On 14 March 2018, type certificate, type certification of the L-39CW was received. On 22 December 2018, the first L-39NG prototype conducted its first flight. In September 2020, the Czech ... [...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".

Williams FJ44
The Williams FJ44 is a family of small, two-spool, turbofan engines produced by Williams International for the light business jet market. Until the recent boom in the very light jet market, the FJ44 was one of the smallest turbofans available for civilian applications. Although a Williams design, Rolls-Royce was brought into the project at an early stage to design, develop, and manufacture an air-cooled high-pressure (HP) turbine for the engine. The FJ44 first flew on July 12, 1988 on the Scaled Composites/Beechcraft Triumph aircraft. The Williams FJ33 is a newer, smaller engine based on the basic FJ44 design. Development Production started in 1992 with the thrust FJ44-1A. The FJ44-1C is derated to . The uprated to FJ44-2A was introduced in 1997. The thrust FJ44-3A was introduced in 2004. In 2005, a new low end version, the FJ44-1AP, was introduced, with a takeoff thrust. Released in 2007 was the new thrust FJ44-4. In 2010 this engine was in use on the Cessna CJ4, a ...

Airworthiness
In aviation, airworthiness is the measure of an aircraft's suitability for Air safety, safe flight. Initial airworthiness is demonstrated by a certificate of airworthiness issued by the civil aviation authority in the state in which the aircraft is registered, and continuing airworthiness is achieved by performing the required Aircraft maintenance, maintenance actions. Certification is based on standards applied by civil aviation authorities. Interoperability is served when national benchmarks adopt standards from international civil and military organizations such as International Civil Aviation Organization (ICAO), European Aviation Safety Agency (EASA), NATO and European Defence Agency (EDA). In the U.S., Title 14, Code of Federal Regulations, Subchapter F, Part 91.7 states: "a) No person may operate an aircraft unless it is in an airworthy condition. b) The pilot in command of a civil aircraft is responsible for determining whether that aircraft is in condition for safe fli ...

Ivchenko AI-25
The Ivchenko AI-25 is a family of military and civilian twin-shaft Turbofan, medium bypass turbofan engines developed by Ivchenko-Progress, Ivchenko OKB of the Soviet Union. It was the first bypass engine ever used on Flight length#Shortest commercial flight, short haul aircraft in the USSR. The engine is still produced by Ukraine, Ukrainian based aircraft engine manufacturing company, Motor Sich. Development The AI-25 was designed to power the Yakovlev Yak-40 tri-jet airliner, often called the first regional jet transport aircraft, and is the starting point for the ZMKB (Progress) DV-2, Lotarev DV-2 turbofan engine. The project was launched in 1965, with the AI-25s first test flight in 1966, and finally cleared for production in 1967. In 1972, the AI-25 was selected for the Poland, Polish PZL M-15 Belphegor, the world's only jet-powered biplane. Development of the AI-25 continued and the uprated AI-25TL was designed for use by the Czechoslovakia, Czechoslovak Aero L-39 Albatr ...

Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Farnborough Airshow
The Farnborough International Airshow is a trade exhibition for the aerospace and defence industries, where civilian and military aircraft are demonstrated to potential customers and investors in Farnborough, Hampshire. Since its first show in 1948, Farnborough has seen the debut of many famous aeroplanes, including the Vickers VC10, Concorde, the Eurofighter, the Airbus A380, and the Lockheed Martin F-35 Lightning II. At the 1958 show, Hawker Hunters of the RAF's Black Arrows executed a 22-aircraft formation loop, setting a new world record. The international trade show runs for five days. Until 2020, the show ran for a full week with the first five days reserved for trade visitors and the general public attending on the weekend. Status The Farnborough International Airshow is the second-largest show of its kind after the Paris Air Show.

Wing Tip
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: * Squared-off * Aluminium tube bow * Rounded * Hoerner style * Winglets * Drooped tips * Raked wingtips * Tip tanks * Sails * Fences * End plates Winglets have become popular additions to high speed aircraft to increase fuel efficiency by reducing drag from wingtip vortices. In lower speed aircraft, the effect of the wingtip shape is less apparent, with only a marginal performance difference between round, square, and Hoerner style tips The slowest speed aircraft, STOL aircraft, may use wingtips to shape airflow for controllability at low airspeeds. Wing tips are also an expression of aircraft design style, so their shape may be influenced by marketing considerations as well as by aerodynamic requirements. Wing tips a ...

Wet Wing
A wet wing (also referred to as ''integral fuel tanks''Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 557. Aviation Supplies & Academics, 1997. ) is an aerospace engineering technique where an aircraft's wing structure is sealed and used as a fuel tank. The use of wet wings has become common among civilian designs, from large transport aircraft, such as airliners, to small general aviation aircraft. Several military aircraft, such as airlifters and aerial refueling tankers, have incorporated the technique as well.Whitford 2004, p. 153. A number of strike aircraft, such as the Grumman A-6 Intruder, have also been furnished with wet wings. While it is technically feasible, studies have found it generally impractical to convert aircraft between wet wing and non-wet wing fuel storage. Features and performance The wet wing offers several advantages. By eliminating the need for separate bladders, tanks, or other containers to house the fuel, weight savings ar ...
