Sud-Ouest Ariel
The Sud-Ouest Ariel is a French two-seat light helicopter designed and built by SNCASO, Sud-Ouest. The helicopter rotors were driven by Tip jet, compressed-air jets at the end of each blade. Design and development The S.O.1100 Ariel I was first flown in 1947, it was a light all-metal helicopter with an enclosed two-seat cabin. Power was provided by a Mathis G8 engine which drove a Turbomeca compressor. The low-pressure air output from the compressor was ducted to each of the three rotor blades to the ends of each blade. At the tip of each blade was a combustion chamber where the air was mixed with fuel and ignited. The Ariel had a short tail boom with twin vertical tail surfaces. On 23 March 1949. an improved S.O.1110 Ariel II was flown, it was a similar configuration to the Ariel I was had revised tail surfaces.Apostolo 1984, p. 94. The final variant was the S.O.1120 Ariel III which had a combined Turbomeca Arrius turbine-compressor rather than the two units of the earlier aircr ...

Experimental Aircraft
An experimental aircraft is an aircraft intended for testing new aerospace technologies and design concepts. The term ''research aircraft'' or ''testbed aircraft'', by contrast, generally denotes aircraft modified to perform scientific studies, such as weather research or geophysical surveying, similar to a research vessel. United States The term "experimental aircraft" also has specific legal meaning in Australia, the United States and some other countries; usually used to refer to aircraft flown with an experimental certificate. In the United States, this also includes most homebuilt aircraft, many of which are based on conventional designs and hence are experimental only in name because of certain restrictions in operation.

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

SNCASO
SNCASO (abbreviated from ''Société nationale des constructions aéronautiques du Sud-Ouest'', or commonly, ''Sud-Ouest'') was a French aircraft manufacturer. Created during 1936 as one of seven nationalised aeronautical manufacturing companies, SNCASO became a key French aircraft manufacturer following the end of the Second World War. It produced numerous innovation aircraft; amongst the company's more notable projects was the first French jet aircraft, the Sud-Ouest Triton, and the first indigenously-developed French helicopter, the Sud-Ouest Djinn. On 1 March 1957, SNCASO merged with another French nationalised aviation company, SNCASE, (''Société nationale des constructions aéronautiques du Sud-Est''), to form Sud Aviation. History Following the resolution of the 1936 general strike of French heavy industry, the government of Léon Blum introduced an act to nationalize the French war industry. The act provided for the creation of seven nationalised aeronautical manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tip Jet
A tip jet is a jet nozzle at the tip of some helicopter rotor blades, used to spin the rotor, much like a Catherine wheel firework. Tip jets replace the normal shaft drive and have the advantage of placing no torque on the airframe, thus not requiring the presence of a tail rotor. Some simple monocopters are composed of nothing but a single blade with a tip rocket. Tip jets can use compressed air, provided by a separate engine, to create jet thrust. Other types use a system that functions similarly to the afterburner (reheat) on a conventional jet engine, except that instead of reheating a gas jet, they serve as the primary heater, creating greater thrust than the flow of pre-compressed air alone; the best description of this is ''thrust augmentation''. Other designs includes ramjets or even a complete turbojet engine. Some, known as Rocket On Rotor systems, involve placing rockets on the tips of the rotor blades that are fueled from an onboard fuel tank. If the helicopter's ...

Turbomeca
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 Rolls ...

Sud-Ouest Djinn
The Sud-Ouest SO.1221 Djinn (alternatively written S.O.1221) is a French two-seat light helicopter designed and manufactured by aircraft manufacturer Sud-Ouest (SNCASO), which was later merged into Sud Aviation. It was the first production French helicopter, as well as being one of the first practical European helicopters to be produced. The Djinn was also the first rotorcraft to harness tip-jet propulsion to enter production. The Djinn was developed to function as a practical implementation of the earlier experimental Sud-Ouest Ariel rotorcraft. Atypically, the rotor was driven by compressed-air jets at the end of each blade, which had the benefit of eliminating the need for an anti-torque tail rotor. On 2 January 1953, the proof-of-concept SO.1220 performed its maiden flight; it was followed by the first of the SO.1221 Djinn prototypes on 16 December 1953. During the subsequence test program, one of the prototypes was recorded as having achieved a world altitude record. Having ...

Fairey Ultra-light Helicopter
The Fairey Ultra-light Helicopter was a small British military helicopter intended to be used for reconnaissance and casualty evacuation, designed by the Fairey Aviation Company. The Ultra-light had been conceived of as a straightforward, low cost and easily transportable helicopter. It lacked any tail rotor due to the decision to propel the rotorcraft using unconventional tip jets positioned at the ends of the rotor blades. It had been selected amongst various competing projects to meet a Ministry of Supply requirement for a lightweight helicopter to be used by the British Army for aerial observation purposes. Early trials with prototypes proved promising, however political factors ultimately undermined the project. The Ultra-light found itself a casualty of the British defence economies of the later 1950s, as well as of intense competition from rival firms who had their own light rotorcraft projects, in particular the Saunders-Roe Skeeter. While Fairey attempted to proceed wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percival P
Percival (, also spelled Perceval, Parzival), alternatively called Peredur (), was one of King Arthur's legendary Knights of the Round Table. First mentioned by the French author Chrétien de Troyes in the tale ''Perceval, the Story of the Grail'', he is best known for being the original hero in the quest for the Grail, before being replaced in later English and French literature by Galahad. Etymology and origin The earliest reference to Perceval is in Chrétien de Troyes's first Arthurian romance ''Erec et Enide'', where, as "Percevaus li Galois" (Percevaus of Wales), he appears in a list of Arthur's knights; in another of Chrétien's romances, '' Cligés'', he is a "renowned vassal" who is defeated by the knight Cligés in a tournament. He then becomes the protagonist in Chrétien's final romance, ''Perceval, the Story of the Grail''. In the Welsh romance ''Peredur son of Efrawg'', the figure goes by the name Peredur. The name "Peredur" may derive from Welsh ''par'' (spea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s French Experimental Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.
