Dassault M.D.320 Hirondelle
The Dassault M.D.320 Hirondelle was a French 14-seat utility transport aircraft of the 1960s, designed and built by Dassault Aviation, in prototype form only. Design and development In 1967 the French Air Force, investigating replacement aircraft for the Douglas DC-3 and Beechcraft 18 twin-engine aircraft being used for light transport and pilot navigation training, solicited proposals from the French industrial community, specifying that any submittals would be powered by Turbomeca Astazou turboprops. In response to this request, Dassault designed and constructed a single prototype M.D.320, later named Hirondelle (''Swallow''). Design and construction were fairly rapid, due to extensive use of Dassault Falcon 20 elements such as the fuselage. The fuselage length and volume were identical to the Falcon 20, and its wing and control surfaces were adaptations of the 20. The Hirondelle was an all-metal low-wing monoplane with swept vertical tail and slightly swept wing and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nacelle
A nacelle ( ) is a "streamlined body, sized according to what it contains", such as an engine, fuel, or equipment on an aircraft. When attached by a pylon entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage. Etymology Like many aviation terms, the word comes from French, in this case from a word for a small boat. Development The development of the Arado Ar 234, merging the four nacelles into two The Arado Ar 234 was one of the first operational jet aircraft with engines mounted in nacelles. During its development, the four jet engines were merged from having four distinct nacelles, all of which contained their own landing gear wheel, to two nacelles with two engi ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

1960s French Military Utility Aircraft
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Dassault Communauté
The Dassault MD.415 Communauté was a 1950s French twin-engined light turboprop transport monoplane built by Dassault Aviation. Only one prototype was built and flown. Development The Dassault company designed a light transport aircraft in the late 1950s, designated MD.415 and later named ''Communauté'', as a potential replacement for the Dassault MD 315 Flamant in its trainer, command transport or ambulance aircraft roles. The Communauté was a cantilever low-wing monoplane with retractable tricycle landing gear with room for two crew and up to ten passengers.

FMA IA 50 Guaraní II
The I.A. 50 Guaraní II is an Argentine utility aircraft designed at the DINFIA (successor to the "Instituto Aerotecnico" - AeroTechnical Institute) in the early 1960s. Design and development In the early 1960s, the Argentine state aviation conglomerate, DINFIA, realised that its IA 35 Huanquero twin-piston engined light transport was becoming outdated, and it was decided to develop a turboprop-engined derivative. While of similar layout to the Huanquero, with both aircraft being twin-engined low-wing monoplane of all metal construction with a twin tail, the new aircraft, the Guaraní, shared only 20% of the structure of the Huanquero. It was powered by two Turbomeca Bastan III engines each rated at .Magnusson 2010, p. 5.Taylor 1962, pp. 4–5. It first flew on 6 February 1962.Taylor 1965, p.3. The aircraft was further developed as the Guaruani II; the main difference being a single swept fin and a shortened rear fuselage. It also used more powerful () Bastan VIA engines. ...

Dassault Falcon 10
The Dassault Mystère/Falcon 10 is an early corporate jet aircraft developed by French aircraft manufacturer Dassault Aviation. Despite its numbering sequence it was actually developed after the Falcon 20, and although it is sometimes considered as a scaled-down version of that aircraft, it was totally redesigned with a non-circular fuselage, a new wing with slotted flaps, a split passenger door and many simplified circuits compared to the Falcon 20. Production began in 1971 and ceased in 1989, but it remains a popular business jet on the second hand market. By 2018, Falcon 10s from the 1970s were priced at $300,000 to $600,000.

Fault-tolerant Design
Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of one or more faults within some of its components. If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naively designed system, in which even a small failure can cause total breakdown. Fault tolerance is particularly sought after in high-availability, mission-critical, or even life-critical systems. The ability of maintaining functionality when portions of a system break down is referred to as graceful degradation. A fault-tolerant design enables a system to continue its intended operation, possibly at a reduced level, rather than failing completely, when some part of the system fails. The term is most commonly used to describe computer systems designed to continue more or less fully operational with, perhaps, a reduction in throughput or an increase in response time in the event of some partial f ...

Turbomeca Astazou XVI
Safran Helicopter Engines, previously known as Turbomeca, is a French manufacturer of low- and medium-power gas turbine turboshaft engines for helicopters. The company also produces gas turbine engines for aircraft and missiles, as well as turbines for land, industrial and marine applications. Since its founding as ''Turbomeca'' during 1938, Safran Helicopter Engines has produced over 72,000 turbines. In its early years, it benefitted greatly from a rearmament programme conducted by the French state; operations were disrupted by the occupation of France during the Second World War, but the company survived and rebuilt quickly during the immediate postwar years. Prominent successes during the Cold War include the use of its Artouste II turboshaft engine to power the new Sud Aviation Alouette II helicopter (the first production turbine-powered helicopter in the world) as well as its involvement in Rolls-Royce Turbomeca Limited (a joint venture with British engine manufacturer ...
