Pusher Configuration
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific (propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were ...

MQ-9 Reaper In Flight 2
The General Atomics MQ-9 Reaper (sometimes called Predator B) is an unmanned aerial vehicle (UAV) capable of remotely controlled or autonomous flight operations developed by General Atomics Aeronautical Systems (GA-ASI) primarily for the United States Air Force (USAF). The MQ-9 and other UAVs are referred to as Remotely Piloted Vehicles/Aircraft (RPV/RPA) by the USAF to indicate their human ground controllers. The MQ-9 is the first hunter-killer UAV designed for long-endurance, high-altitude surveillance. In 2006, the then–Chief of Staff of the United States Air Force General T. Michael Moseley said: "We've moved from using UAVs primarily in intelligence, surveillance, and reconnaissance roles before Operation Iraqi Freedom, to a true hunter-killer role with the Reaper." The MQ-9 is a larger, heavier, and more capable aircraft than the earlier General Atomics MQ-1 Predator; it can be controlled by the same ground systems used to control MQ-1s. The Reaper has a 950- shaft-h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tractor Configuration
In aviation, the term tractor configuration refers to an aircraft constructed in the standard configuration with its engine mounted with the propeller in front of it so that the aircraft is "pulled" through the air. Oppositely, the pusher configuration places the airscrew behind and propels the aircraft forward. Through common usage, the word "propeller" has come to mean any airscrew, whether it actually propels or pulls the plane. In the early years of powered aviation both tractor and pusher designs were common. However, by the midpoint of the First World War, interest in pushers declined and the tractor configuration dominated. Today, propeller-driven aircraft are assumed to be tractors unless it is stated otherwise. Origins The first airplane to have a "tractor" configuration was the Goupy No.2 (first flight on 11 March 1909) designed by Mario Calderara and financed by Ambroise Goupy at the French firm Blériot Aéronautique. When it was constructed, it was the fast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Farman III
The Farman III, also known as the Henry Farman 1909 biplane, was an early French aircraft designed and built by Henry FarmanHenry Farman's "No.3" Biplane ''Flight'', 24 April 1909, p. 235. in 1909. Its design was widely imitated, so much so that aircraft of similar layout were generally referred to as being of the "Farman" type. Background Henry Farman's first aircraft had been bought from the brothers in 1907. Soon after his first flights Farman began to modify and improve the design of the aircraft, which was known as either the Farman I or[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Farman
Henri Farman (26 May 1874– 17 July 1958) was a British-French aviator and aircraft designer and manufacturer with his brother Maurice Farman. Before dedicating himself to aviation he gained fame as a sportsman, specifically in cycling and motor racing. Henri took French nationality in 1937.Obituary: ''Flight'' Family and early life Henri Farman was born in Paris, France, and was baptised as Harry Edgar Mudford Farman. He was a son of Thomas Frederick Farman, the Paris correspondent of the ''London Standard.''"Aviators at Rheims. Personal Sketches: M. Henri Farman."

Eugene Burton Ely
Eugene Burton Ely (October 21, 1886 – October 19, 1911) was an American aviation pioneer, credited with the first shipboard aircraft take off and landing. Background Ely was born in Williamsburg, Iowa, and raised in Davenport, Iowa. Having completed the eighth grade, he graduated from Davenport Grammar School 4 in January 1901. Although some sources indicate that he attended and graduated from the Iowa State University in 1904 (when he would have been 17), the registrar of ISU reports that there is no record of his having done so – nor did he attend the University of Iowa or the University of Northern Iowa. Ely likewise does not appear in the graduations lists for Davenport High School. By 1904, Ely was employed as a chauffeur to the Rev. Fr. Smyth, a Catholic priest in Cosgrove, Iowa, who shared Ely's love of fast driving; in Father Smyth's car (a red Franklin), Ely set the speed record between Iowa City and Davenport. Ely was living in San Francisco at the time of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss Model D
The 1911 Curtiss Model D (or frequently "Curtiss Pusher") was an early United States pusher aircraft with the engine and propeller behind the pilot's seat. It was among the first aircraft in the world to be built in any quantity, during an era of trial-and-error development and equally important parallel technical development in internal combustion engine technologies. It was also the aircraft type which made the first takeoff from the deck of a ship (flown by Eugene B. Ely off the deck of on November 14, 1910, near Hampton Roads, Virginia) and made the first landing aboard a ship () on January 18, 1911, near San Francisco, California. It was originally fitted with a foreplane for pitch control, but this was dispensed with when it was accidentally discovered to be unnecessary. The new version without the foreplane was known as the Headless Pusher. Like all Curtiss designs, the aircraft used ailerons, which first existed on a Curtiss-designed airframe as quadruple "wing-tip" ...

Voisin 1907 Biplane
The 1907 Voisin biplane (designated the Voisin II by the 1913 edition of ''Jane's All the World's Aircraft''), was the first successful powered aircraft designed by aeronautical engineer and manufacturer Gabriel Voisin. It was used by the French aviator Henri FarmanBorn in France to British father, Henri (or Henry) Farman took French nationality in 1937 to make the first heavier-than-air flight lasting more than a minute in Europe, and also to make the first full circle. The first examples of the aircraft were known by the name of their owners, for instance the Delagrange I, or the Henri Farman n°1. Farman made many modifications to his aircraft, and these were incorporated into later production aircraft built by Voisin. The type enjoyed widespread success, and around sixty were built. Background Between 1904 and 1908 there was fierce competition between European aviation experimenters attempting to achieve powered heavier-than-air flight. Although the Wright Brothers ...

Santos-Dumont 14-bis
The ''14-bis'' (french: Quatorze-bis), (), also known as ("bird of prey" in French), was a pioneer era, canard-style biplane designed and built by Brazilian aviation pioneer Alberto Santos-Dumont. In 1906, near Paris, the ''14-bis'' made a manned powered flight that was the first to be publicly witnessed by a crowd. Background In June 1905, French aviator Gabriel Voisin had flown a glider towed by a fast boat on the river Seine, making a flight of over . The glider's wing and tail were made up of Hargrave cells, a box kite-like structure that provided a degree of inherent stability. This established the Hargrave cell as a configuration useful not only for kites but also for heavier-than-air aircraft. Santos-Dumont was living in Paris at the time, and was one of the most active "aeronauts" in Europe, having developed a series of non-rigid airships that displayed unparalleled agility, speed, endurance, and ease of control. Santos-Dumont met Voisin at the end of 1905, and commi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
