Armstrong Whitworth F.K.13
The Armstrong Whitworth F.K.8 was a British two-seat general-purpose biplane built by Armstrong Whitworth during the First World War. The type served alongside the better known R.E.8 until the end of the war, at which point 694 F.K.8s remained on RAF charge. Design and development The aircraft, originally designated the F.K.7, was designed by Dutch aircraft designer Frederick Koolhoven as a replacement for the Royal Aircraft Factory B.E.2c and the Armstrong Whitworth F.K.3. It was a sturdier aircraft than the F.K.3, with a larger fuselage and wings, and was powered by a 160 hp (110 kW) Beardmore water-cooled engine. The undercarriage used oleo shock absorbers and the observer was equipped with a Scarff ring mounting for a .303 in (7.7 mm) Lewis machine gun. No armament was initially provided for the pilot. The rudder featured a long, pointed horn-balance. The type was fitted with basic dual controls for the observer to control the aircraft if the pilot ...

Bomber
A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch aerial torpedo, torpedoes, or deploy air-launched cruise missiles. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure, reducing industrial output, or inflicting massive civilian casualties to an extent deemed to force surrender. Tactical bombing is aimed at countering enemy military activity and in supporting offensive operations, and is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping. Bombs were first dropped from an aircraft during the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Seco ...

Oleo Strut
An oleo strut is a pneumatic air–oil hydraulic shock absorber used on the landing gear of most large aircraft and many smaller ones. This design cushions the impacts of landing and damps out vertical oscillations. It is undesirable for an airplane to bounce on landing as it could lead to a loss of control, and the landing gear should not add to this tendency. A steel coil spring stores impact energy from landing and then releases it, while an oleo strut instead absorbs this energy, reducing bounce. As the strut compresses, the spring rate increases dramatically because the air is being compressed. The viscosity of the oil damps the rebound movement. History The original design for the oleo-pneumatic shock-absorbing strut was patented by British manufacturing conglomerate Vickers Armstrong during 1915. It had been derived from the recuperative gear design of the Vickers gun, controlling recoil by forcing oil through precisely sized orifices. Vickers' oleo strut was first applie ...

Reconnaissance
In military operations, military reconnaissance () or scouting is the exploration of an area by military forces to obtain information about enemy forces, the terrain, and civil activities in the area of operations. In military jargon, reconnaissance is abbreviated to ''recce'' (in British, Canadian, Australian English) and to ''recon'' (in American English), both derived from the root word ''reconnoitre'' / ''reconnoitering''. The types of reconnaissance include patrolling the local area of operations and long-range reconnaissance patrols, which are tasks usually realized in the United States of America by U.S. Army Rangers, cavalry scouts, and military intelligence specialists, using navy ships and submarines, Aerial reconnaissance, reconnaissance aircraft, satellites to collect raw intelligence; and establishing observation posts. Moreover, espionage is different from reconnaissance, because spies work as civilians in enemy territory. Etymology The word is derived from the ...

Palestine (region)
The region of Palestine, also known as historic Palestine, is a geographical area in West Asia. It includes the modern states of Israel and Palestine, as well as parts of northwestern Jordan in some definitions. Other names for the region include Canaan, the Promised Land, the Land of Israel, or the Holy Land. The earliest written record Timeline of the name Palestine, referring to Palestine as a geographical region is in the ''Histories (Herodotus), Histories'' of Herodotus in the 5th century BCE, which calls the area ''Palaistine'', referring to the territory previously held by Philistia, a state that existed in that area from the 12th to the 7th century BCE. The Roman Empire conquered the region and in 6 CE established the province known as Judaea (Roman province), Judaea. In the aftermath of the Bar Kokhba revolt (132–136 CE), the province was renamed Syria Palaestina. In 390, during the Byzantine period, the region was split into the provinces of Palaestina Prima, Pal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macedonia (region)
Macedonia ( ) is a geographical and historical region of the Balkan Peninsula in Southeast Europe. Its boundaries have changed considerably over time; however, it came to be defined as the modern geographical region by the mid-19th century.

Bristol F
Bristol () is a cathedral city, unitary authority area and ceremonial county in South West England, the most populous city in the region. Built around the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. The county is in the West of England combined authority area, which includes the Greater Bristol area ( eleventh most populous urban area in the United Kingdom) and nearby places such as Bath. Bristol is the second largest city in Southern England, after the capital London. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to t ...

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 (aeronautics), 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 French Third Republic, France and German Empire, Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounti ...

Upavon
Upavon is a rural village and civil parish in the county of Wiltshire, England. As its name suggests, it is on the upper portion of the River Avon which runs from north to south through the village. It is on the north edge of Salisbury Plain about south of Pewsey, southeast of the market town of Devizes, and north of the cathedral city of Salisbury. The A345 and A342 roads run through the village. History Occupation of the area dates back to the Iron Age and Romano-British settlement at Casterley Camp, approximately southwest of the current village, and to the southeast was the small Iron Age settlement of Chisenbury Camp. The first mention of Upavon is in the 1086 Domesday Book as ''Oppavrene''; although no population was recorded, it can be estimated that the village supported some 200 to 250 people. The village prospered during the 12th and 13th centuries and started to develop features that are recognisable today. A large Norman church replaced the previous Saxon ...
