Fournier RF7
The Fournier RF7 was a single-seat motorglider designed and built in prototype form by René Fournier in France in 1970 and intended for series production by Sportavia-Pützer in Germany. Design and development The RF7 was a conventional motorglider design derived from Fournier's RF 4D, a low-wing cantilever monoplane with an engine mounted in tractor configuration in the nose.Taylor 1989, p.75 The sailplane-style undercarriage consisted of a retractable mainwheel, a fixed tailwheel, and small outriggers under each wing. Compared to the RF 4. the wings were shorter and the tailplane surfaces larger. The ailerons were also larger,"Hanover Report", p.720 and the RF7 was fully stressed for aerobatics.''Interavia'', p.1225 Construction of the prototype ( registered ''F-WPXV'') began in July 1969, and the aircraft first flew on 5 March 1970. It was displayed at the Hanover Air Show the following month, where the journal ''Flight International ''Flight International'' is a m ...

Hanover Air Show
Hanover (; german: Hannover ; nds, Hannober) is the capital and largest city of the German state of Lower Saxony. Its 535,932 (2021) inhabitants make it the 13th-largest city in Germany as well as the fourth-largest city in Northern Germany after Berlin, Hamburg and Bremen. Hanover's urban area comprises the towns of Garbsen, Langenhagen and Laatzen and has a population of about 791,000 (2018). The Hanover Region has approximately 1.16 million inhabitants (2019). The city lies at the confluence of the River Leine and its tributary the Ihme, in the south of the North German Plain, and is the largest city in the Hannover–Braunschweig–Göttingen–Wolfsburg Metropolitan Region.

Motor Gliders
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which ...

Fournier Aircraft
Fournier is a French surname. It is a former designation of baker. Prior to the 1900s it was the designation of a firefighter. The firefighter became by default the baker as he was normally in charge of the communal ovens. As fewer people kneaded their own bread, he commenced this task, became more skilled and thus became the baker. Notable people with the surname include: *Alain Fournier, computer graphics researcher *Alain-Fournier (Henri-Alban Fournier), French writer * Alphonse Fournier (1893–1961), Canadian politician *Amédée Fournier, French bicycle racer * Catherine Fournier (Canadian politician) (born 1992), Canadian politician * Christophe Fournier, president of the Médecins Sans Frontières organisation * Claude Fournier (1745–1825), a personality of the French Revolution, nicknamed l'Americain * Claude Fournier (born 1931), filmmaker *Colin Fournier, professor of The Bartlett School of Architecture *Edgar Fournier, Canadian politician *Eduardo Fournier, Chilean f ...

1970s French Sport Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 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 * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a time. The NAA al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
