AD Scout
The AD Scout (also known as the Sparrow) was designed by Harris Booth of the British Admiralty's Air Department as a fighter aircraft to defend Britain from Zeppelin bombers during World War I. Design and development The Scout was a very unconventional aircraft – a biplane with a fuselage pod mounted on the ''upper'' wing. A twin-rudder tail was attached by four booms, and it was provided with an extremely narrow-track undercarriage. The primary armament was intended to be a 2-pounder recoilless Davis Gun, but this was never fitted. Four prototypes were ordered in 1915, and two each were built by Hewlett & Blondeau and the Blackburn Aeroplane & Motor Company. Operational history Trials flown by pilots of the Royal Naval Air Service at Chingford proved the aircraft to be seriously overweight, fragile, sluggish, and difficult to handle, even on the ground. The project was abandoned, and all four prototypes were scrapped. Operators ; *Royal Naval Air Service Specificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Plane
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual ro ...

Gnome Monosoupape 9 Type B-2
The ''Monosoupape'' ( French for single-valve), was a rotary engine design first introduced in 1913 by Gnome Engine Company (renamed Gnome et Rhône in 1915). It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the ''Monosoupape'' engines some of the most reliable of the era. British aircraft designer Thomas Sopwith described the ''Monosoupape'' as "one of the greatest single advances in aviation". Monosoupape engines were produced under license in large numbers in Britain, Russia, Italy and the US. Two differing nine-cylinder versions were produced, the 9B-2 and 9N, with differing displacements giving the larger displacement 9N version a nearly-cylindrical shaped crankcase, with the 9N also adopting a dual ignition system for increased flight safety. 2,188 units were produced under license in Britain, with an uprated version later built in Ru ...

Aircraft First Flown In 1915
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin-boom Aircraft
A twin-boom aircraft has two wikt:Longitudinal, longitudinal auxiliary spars, or “auxiliary booms” , that may contain ancillary components such as fuel tank, fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the Empennage, tail surfaces, although on some types such as the Rutan Grizzly, Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from Twin-fuselage aircraft, twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin-fuselage aircraft, twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, ...

1910s British Fighter Aircraft
Year 191 ( CXCI) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 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. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V.

Before leaving, Dong Zhuo orders his troops to loot the tombs of the Han emperors, and then destroy Luoyang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburn Aircraft
Blackburn Aircraft Limited was a British aircraft manufacturer from 1914 to 1963 that concentrated mainly on naval and maritime aircraft. History Blackburn Aircraft was founded by Robert Blackburn (aviation pioneer), Robert Blackburn and Jessy Blackburn, who built his first aircraft in Leeds in 1908 with the company's Olympia Works at Roundhay opening in 1914. The Blackburn Aeroplane & Motor Company was created in 1914 and established in a new factory at Brough, East Riding of Yorkshire, Brough, East Riding of Yorkshire in 1916. Robert's brother Norman Blackburn (aviation pioneer), Norman Blackburn later became managing director. Blackburn acquired the Cirrus aero engines, Cirrus-Hermes Engineering company in 1934, beginning its manufacture of aircraft engines. However an updated range of engines was under development and Blackburn wanted to wait until it was established before giving its name to them, so Cirrus Hermes Engineering was retained as a separate company for the time ...

Air Department Aircraft
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Davis Gun
The Davis gun was the first true recoilless gun developed and taken into service. It was developed by Commander Cleland Davis of the United States Navy in 1910, just prior to World War I. Development Davis' design connected two guns back to back, with the backwards-facing gun loaded with lead balls and grease of the same weight as the shell in the other gun, acting as a counter. His idea was used experimentally by the British and Americans as an anti-Zeppelin and anti-submarine weapon mounted on the British Handley Page O/100 and O/400 bombers and the American Curtiss Twin JN and Curtiss HS-2L and H-16 flying boats. The direct development of the gun ended with the end of World War I in November 1918, but the firing principle has been copied by later designs. Description The gun was made in three sizes: 2-pounder, 6-pounder and 12-pounder; , , and in caliber respectively, firing , , and shells. The 3-inch gun carried a pressure of 15 tons per square inch (2,109 kg per cm2) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
