Gérin 1936 Varivol Biplane
The Gerin Varivol was a 1930s France, French research aircraft designed and built by Jacques Gerin. Only one aircraft was flown during 1936 before it was destroyed in an accident. Design and development The Varivol was an odd looking biplane with a deep and bulky fuselage with a knife edge rear where the rudder was attached and a braced variable-incidence tailplane was mounted on top of the rear fuselage. The unique feature of the aircraft were the two narrow-chord biplane wings in an inverted sesquiplane configuration. The wings were Flying wires, wire-braced and had one interplane strut on each side. The upper wing normally had an area of but additional flexible surfaces inside the fuselage could be extended using an electrical motor to increase the wing area to . It was also possible to change the camber of the wings when extended. The Varivol was powered by a Salmson Radial engine, radial piston engine with a two-bladed propeller. It was first tested in a wind tunnel at Chala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1930s French Experimental Aircraft
Year 193 ( CXCIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

Illustrated Encyclopedia Of Aircraft
The ''Illustrated Encyclopedia of Aircraft'' was a weekly partwork magazine by Aerospace Publishing (an imprint of Orbis Publishing) which was published in the United Kingdom (and sold in other countries too) during the early 1980s. The magazine was intended to eventually make up a multi-volume encyclopedia dedicated to aviation. First issued in 1981, the partwork comprised 216 issues, each of twenty pages (plus the covers), making up eighteen volumes (4280 pages). The first two issues were sold together for the price of one, subsequent issues were sold on their own. Empty binders for each volume (of twelve issues) were also sold. These binders were dark blue in colour and contained the imprint of a Panavia Tornado on the front. They held the issues using a metal strip that was threaded through the staples of each issue to hold them in place. Each issue consisted of four separate sections. The final two parts (215 and 216), issued in 1985, comprised the index for the encyclope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Angers (, , ;) is a city in western France, about southwest of Paris. It is the Prefectures of France, prefecture of the Maine-et-Loire department and was the capital of the province of Duchy of Anjou, Anjou until the French Revolution. The inhabitants of both the city and the province are called ''Angevins'' or, more rarely, ''Angeriens''.

Chalais-Meudon
Chalais-Meudon is an aeronautical research and development centre in Meudon, to the south-west of Paris. It was originally founded in 1793 in the nearby Château de Meudon and has played an important role in the development of French aviation. Starting with the development and production of balloons, the site has been a centre of aviation development, mainly but not exclusively military, ever since. Many famous French aircraft designers and engineers worked here or used its resources, such as hangars, wind tunnels, and laboratories to further their activities, and the site continues as an aerospace research hub into the 21st century. The site was the original home of the world's first aviation museum, now known as the Musée de l'air et de l'espace at Paris–Le Bourget Airport. History Balloons The story of aviation at Chalais-Meudon starts in October 1793 when the French Committee of Public Safety ordered the construction of an observation balloon capable of carrying two obs ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is als ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Interplane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplanes, including the monoplanes and biplanes, which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more ...
