Dassault Mercure
The Dassault Mercure is a twin-engined narrow-body jet-powered airliner developed and manufactured by French aircraft firm Dassault Aviation. According to Dassault, it was the first large-scale European cooperative civil aeronautics programme. During 1967, the Mercure was proposed as a French counterpart to the American Boeing 737. It was Dassault's first venture into the commercial jet airliner market, the company having traditionally built fighters and executive jets. On 28 May 1971, the prototype conducted its maiden flight, while the type entered service on 4 June 1974 with French airline Air Inter. Attempts were made to market the type in the US, including partnerships with American manufacturers Douglas, Lockheed and General Dynamics, with the vision of producing it in the United States. However, the Mercure had very little success on the market, which has been attributed to several factors, including a lack of range in comparison to rival aircraft. As a consequence, the ...

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 ...

Rolls-Royce Spey
The Rolls-Royce Spey (company designations RB.163 and RB.168 and RB.183) is a low-bypass turbofan engine originally designed and manufactured by Rolls-Royce that has been in widespread service for over 40 years. A co-development version of the Spey between Rolls-Royce and Allison in the 1960s is the Allison TF41. Intended for the civilian jet airliner market when it was being designed in the late 1950s, the Spey concept was also used in various military engines, and later as a turboshaft engine for ships known as the Marine Spey, and even as the basis for a new civilian line, the Rolls-Royce RB.183 Tay. Aviation versions of the base model Spey have accumulated over 50 million hours of flight time. In keeping with Rolls-Royce naming practices, the engine is named after the River Spey. Design and development In 1954 Rolls-Royce introduced the first commercial bypass engine, the Rolls-Royce Conway, with 17,500 lbf (78 kN) of thrust aimed at what was then the "large end" o ...

Air Enthusiast
''Air Enthusiast'' was a British, bi-monthly, aviation magazine, published by the Key Publishing group. Initially begun in 1974 as ''Air Enthusiast Quarterly'', the magazine was conceived as a historical adjunct to '' Air International'' magazine. ''Air International'' was (and still is) involved with current aviation topics and the ''Quarterly'' concerned itself with historical matters. Each issue contained 80 pages; as a result certain articles were divided and each part appeared over a number of issues. ''Air Enthusiast'' was illustrated with colour and black-and-white photos, diagrams, profiles and three-view drawings. Earlier issues featured cutaway drawings, but these were dropped. The articles provided detail for varieties of aircraft An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from ...

Pratt & Whitney JT8D
The Pratt & Whitney JT8D is a low-bypass (0.96 to 1) turbofan engine introduced by Pratt & Whitney in February 1963 with the inaugural flight of the Boeing 727. It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft. Eight models comprise the JT8D standard engine family, covering the thrust range from 12,250 to 17,400 pound-force, pounds-force (62 to 77 kN), and power Boeing 727, 727, Boeing 737, 737-100/200, and McDonnell Douglas DC-9, DC-9. The updated JT8D-200 family, covering the 18,900 to 21,000 pound-force, pounds-force (84 to 93 kN), powers the McDonnell Douglas MD-80, MD-80 and re-engined Boeing 727, Super 27 aircraft. The Volvo RM8 was license-built in Sweden for the Saab 37 Viggen fighter. Pratt & Whitney also sells static versions for powerplant and ship propulsion as the FT8.

Paris–Le Bourget Airport
Paris–Le Bourget Airport (french: link=no, Aéroport de Paris-Le Bourget) is an airport located within portions of the communes of Le Bourget, Bonneuil-en-France, Dugny and Gonesse, north-northeast of Paris, France. Once Paris's principal airport, it is now used only for general aviation, including business jet operations. It also hosts air shows, most notably the Paris Air Show. The airport is operated by Groupe ADP under the brand Paris Aéroport. History The airport started commercial operations in 1919 and was Paris's only airport until the construction of Orly Airport in 1932. It is famous as the landing site for Charles Lindbergh's historic solo transatlantic crossing in 1927 in the ''Spirit of St. Louis'', and had been the departure point two weeks earlier for the French biplane ''L'Oiseau Blanc (The White Bird)'', which took off in an attempt at a transatlantic flight, but then mysteriously disappeared.Godspeed, Charles and Francois"The Secret of The White Bird."

Mockup
In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup may be a ''prototype'' if it provides at least part of the functionality of a system and enables testing of a design. Mock-ups are used by designers mainly to acquire feedback from users. Mock-ups address the idea captured in a popular engineering one-liner: "You can fix it now on the drafting board with an eraser or you can fix it later on the construction site with a sledge hammer". Applications Mockups are used as design tools virtually everywhere a new product is designed. Mockups are used in the automotive device industry as part of the product development process, where dimensions, overall impression, and shapes are tested in a wind tunnel experiment. They can also be used to test consumer reaction. Systems engineering Mockups, wireframes and prototypes are not so cleanl ...

Mercury (mythology)
Mercury (; la, Mercurius ) is a major god in Roman religion and mythology, being one of the 12 Dii Consentes within the ancient Roman pantheon. He is the god of financial gain, commerce, eloquence, messages, communication (including divination), travelers, boundaries, luck, trickery, and thieves; he also serves as the guide of souls to the underworld. In Roman mythology, he was considered to be either the son of Maia, one of the seven daughters of the Titan Atlas, and Jupiter, or of Caelus and Dies. In his earliest forms, he appears to have been related to the Etruscan deity Turms; both gods share characteristics with the Greek god Hermes. He is often depicted holding the caduceus in his left hand. Similar to his Greek equivalent Hermes, he was awarded a magic wand by Apollo, which later turned into the caduceus, the staff with intertwined snakes. Etymology The name "Mercury" is possibly related to the Latin words ' ("merchandise"; cf. ''merchant'', ''commerce'', etc ...

Dassault Mirage
Mirage is a name given to several types of jet aircraft designed by the French company Dassault Aviation (formerly Avions Marcel Dassault), some of which were produced in different variants. Most were supersonic fighters with delta wings. The most successful was the Mirage III in its many variants and derivatives, which were widely produced and modified both by Dassault and by other companies. Some variants were given other names, while some otherwise unrelated types were given the Mirage name. Early prototypes * MD550 Mystère Delta, the original Dassault experimental delta jet, which provided the baseline for the main Mirage series. Two were built, later renamed Mirage I and II respectively: ** Mirage I, being the MD550-01 renamed. ** Mirage II, being the MD550-02 renamed. Mirage III/5/50 series The most successful line of Mirages were a family of supersonic delta-winged fighters, all sharing the same basic airframe but differing in powerplant, equipment and minor details.
