Fokker E.I
The Fokker E.I was the first fighter aircraft to enter service with the Fliegertruppe of the Deutsches Heer in World War I. Its arrival at the front in mid-1915 marked the start of a period known as the " Fokker Scourge" during which the E.I and its successors achieved a measure of air superiority over the Western Front. Design and development The E.I was essentially an armed version of the Fokker M.5K single-seat reconnaissance aircraftWinchester 2006, p. 15. (military designation A.III), which was in turn very closely based on the design of the 1913 French Morane-Saulnier Type H. Like the Morane, the Fokker was an externally braced mid-winged monoplane with a vertically tapered box section fuselage, with fully movable horizontal and vertical stabilizing surfaces, also known as "flying" surfaces, giving the pilot the usual tail control functions; roll control was achieved through controlled wing warping, as was conventional in contemporary monoplanes.Winchester 2006, pp. 15 ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops ( skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amphibio ...

Fokker M5K-MG E5-15
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Parschau
''Leutnant'' Otto Parschau (11 November 1890 – 21 July 1916) was a German World War I flying ace and recipient of the Pour le Mérite, Royal House Order of Hohenzollern, and Iron Cross, First Class. He was noted as one of the pre-eminent aces on the Fokker Eindecker. He was one of the world's first flying aces. Parschau and ''Leutnant'' Kurt Wintgens were the pilots chosen to fly the prototype of the revolutionary Fokker Eindecker fighter plane with a machine gun synchronized to fire safely through its propeller arc via use of a gun synchronizer. Background Parschau was born in Klausen (now Klutznick, Poland), in the Allenstein district of East Prussia. He became a commissioned officer a year after having joined the ''Infanterie-Regiment Nr. 151'' in 1910. Parschau was trained as a pilot in Johannisthal, Darmstadt, and in Hanover and received his licence on 4 July 1913. World War I Upon the outbreak of hostilities in August 1914 Parschau was already serving with the ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoulder Wing
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 a ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maschinengewehr 08
The ''Maschinengewehr'' 08, or MG 08, was the German Army's standard machine gun in World War I and is an adaptation of Hiram S. Maxim's original 1884 Maxim gun. It was produced in a number of variants during the war. The MG 08 served during World War II as a heavy machine gun in many German infantry divisions, although by the end of the war it had mostly been relegated to second-rate fortress units. The ''Maschinengewehr'' 08 (or MG 08)—so-named after 1908, its year of adoption—was a development of the license made ''Maschinengewehr'' 01. The firing rate depends on the lock assembly used and averages 500 rounds per minute for the Schloss 08 and 600 rounds per minute for the Schloss 16. The gun used 250-round fabric belts of 7.92×57mm ammunition. It was water-cooled, using a jacket around the barrel that held approximately of water. Using a separate attachment sight with range calculator for indirect fire, the MG 08 could be operated from cover. Additional telescopic sig ...

Parabellum MG14
The Parabellum MG 14 was a 7.92 mm caliber World War I machine gun built by Deutsche Waffen und Munitionsfabriken. It was a redesign of the Maschinengewehr 08 machine gun (itself an adaptation of the Maxim gun) system intended for use on aircraft and zeppelins. Like the earlier Vickers machine gun, it used a toggle action that broke upwards rather than downwards, the opposite way to the MG 08, making for a much more compact receiver. The fusee spring was replaced with an internal spring design, the breech block was completely different and the spent cartridges dropped out the bottom of the receiver, rather than being ejected forward through a hole under the breech from the receiver. There appears to be no action or receiver parts interchangeable with the MG 08. The MG 08's belt-style ammunition feed was enclosed in a drum, the recoil casing was lightened and the cooling jacket was modified for air- instead of water-cooling. The rate of fire was 700 rounds/minute. The belt was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synchronization Gear
A synchronization gear (also known as a gun synchronizer or interrupter gear) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target. There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate. In practice, all known gears worked on the principle of actively triggering each shot, in the manner of a semi-automatic weapon. Design and experimentation with gun synchronization had been underway in France and Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounting a fixed armament firing in the direction of flight (in 19 ...

41xx Steel
41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include ''chrome-moly'', ''cro-moly'', ''CrMo'', ''CRMO'', ''CR-MOLY'', and similar). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded, requiring thermal treatment both before and after welding to avoid cold cracking. While these grades of steel do contain chromium, it is not in great enough quantities to provide the corrosion resistance found in stainless steel. Examples of applications for 4130, 4140 and 4145 include structural tubing, bicycle frames, gas bottles for transportation of pressurized gases, firearm parts, clutch and flywheel components, and roll cages. 4150 stands out as being one of the steels accepted for use ...

Wing Spar
In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings while on the ground. Other structural and forming members such as ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all. Where a single spar carries most of the force, it is known as the main spar. Spars are also used in other aircraft aerofoil surfaces such as the tailplane and fin and serve a similar function, although the loads transmitted may be different from those of a wing spar. Spar loads The wing spar provides the majority of the weight support and dynamic load integrity of cantilever monoplanes, often coupled with the strength of the wing 'D' box itself. Together, these two structural components collectively provide the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
