R.E.P. 1
The Esnault-Pelterie R.E.P. 1 and the R.E.P. 2 were experimental aircraft built and flown in France in the early twentieth century by Robert Esnault-Pelterie. These aircraft are historically significant because they were the first to employ a joystick as their main flight control. R.E.P. 1 The REP 1 was a single-seat tractor configuration monoplane powered by a seven-cylinder two-row semi-radial engine driving a four-bladed propeller with aluminium blades rivetted to steel tubes. The fuselage was made largely of steel tubing covered in varnished silk and the wings of wood. An elongated triangular fixed horizontal stabiliser was mounted on top of the rear fuselage with a rectangular elevator mounted on the trailing edge, and a fixed fin and rudder were mounted under the fuselage. Lateral control was effected by wing-warping. The main landing gear consisted of a single centrally mounted wheel mounted on a pneumatic damper, with a small tailwheel mounted on the rudder. Lar ...

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 Wikimedia project, 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 Magazine, 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".

Balanced Rudder
Balanced rudders are used by both ships and aircraft. Both may indicate a portion of the rudder surface ahead of the hinge, placed to lower the control loads needed to turn the rudder. For aircraft the method can also be applied to elevators and ailerons; all three aircraft control surfaces may also be mass balanced, chiefly to avoid aerodynamic flutter. Ships A balanced rudder is a rudder in which the axis of rotation of the rudder is behind its front edge. This means that when the rudder is turned, the pressure of water caused by the ship's movement through the water acts upon the forward part to exert a force which increases the angle of deflection, so counteracting the pressure acting on the after part, which acts to reduce the angle of deflection. A degree of semi-balance is normal to avoid rudder instability i.e. the area in front of the pivot is less than that behind. This allows the rudder to be moved with less effort than is necessary with an unbalanced rudder. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-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 ...

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is int ...

''L’Aérophile'' ("The Aerophile") was a French aviation magazine published from 1893 to 1947. It has been described as "the leading aeronautical journal of the world" around 1910. History and contents ''L’Aérophile'' was founded and run for many years by Georges Besançon. In 1898 it became the official journal of the Aéro Club of France. Important developments in early aviation were documented in its pages: * Octave Chanute's April 1903 speech to the Aéro-Club describing the excitement of the gliding experiments done by his group in 1896/7 and of the Wright brothers was printed in April, 1903.

Reims
Reims ( , , ; also spelled Rheims in English) is the most populous city in the French department of Marne, and the 12th most populous city in France. The city lies northeast of Paris on the Vesle river, a tributary of the Aisne. Founded by the Gauls, Reims became a major city in the Roman Empire. Reims later played a prominent ceremonial role in French monarchical history as the traditional site of the coronation of the kings of France. The royal anointing was performed at the Cathedral of Reims, which housed the Holy Ampulla of chrism allegedly brought by a white dove at the baptism of Frankish king Clovis I in 496. For this reason, Reims is often referred to in French as ("the Coronation City"). Reims is recognized for the diversity of its heritage, ranging from Romanesque to Art-déco. Reims Cathedral, the adjacent Palace of Tau, and the Abbey of Saint-Remi were listed together as a UNESCO World Heritage Site in 1991 because of their outstanding Romanesque ...

Grande Semaine D'Aviation
The ''Grande Semaine d'Aviation de la Champagne'' was an 8-day aviation meeting held near Reims in France in 1909, so-named because it was sponsored by the major local champagne growers. It is celebrated as the first international public flying event, confirming the viability of heavier-than-air flight. It marked the first contest for the prestigious Gordon Bennett Trophy, sponsored by Gordon Bennett, publisher of the New York Herald, won by American Glenn Curtiss in competition with Louis Bleriot. The meeting saw the breaking of the world record for distance, a flight of 180 km (110 mi) by Henri Farman, as well as the debut of the lightweight Gnome engine, which would achieve much acclaim. Grande Semaine de la Champagne Tribunes from the sky . The ''Grand Semaine d'Aviation'', held between 22 August and 29 August 1909, was sponsored by many of the leading makers of champagne including Moët et Chandon and Mumm and organised by a committee headed by the Marqu ...
