Polikarpov R-2
The Airco DH.9A was a British single-engined light bomber designed and first used shortly before the end of the First World War. It was a development of the unsuccessful Airco DH.9 bomber, featuring a strengthened structure and, crucially, replacing the under-powered and unreliable inline 6-cylinder Siddeley Puma engine of the DH.9 with the American V-12 Liberty engine. Colloquially known as the "Ninak" (from the phonetic alphabet treatment of designation "nine-A"), it served on in large numbers for the Royal Air Force following the end of the war, both at home and overseas, where it was used for colonial policing in the Middle East, finally being retired in 1931. Over 2,400 examples of an unlicensed version, the Polikarpov R-1, were built in the Soviet Union, the type serving as the standard Soviet light bomber and reconnaissance aircraft through the 1920s. Design and development The DH.9A was planned as an improved version of the existing Airco DH.9. The DH.9 was a disappoint ...

Light Bomber
A light bomber is a relatively small and fast type of military bomber aircraft that was primarily employed before the 1950s. Such aircraft would typically not carry more than one ton of ordnance. The earliest light bombers were intended to drop their bombs in level flight over a target. During World War I some air forces began to distinguish between light bombers and the earliest purpose-built attack aircraft which carried out ground attack, close air support, anti-shipping and similar missions. After World War I, attack aircraft were typically identifiable by their ability to carry multiple fixed machine guns, automatic cannons and rockets in addition to bombs. Light bombers have often served as attack aircraft and vice versa. Purpose-built light bombers disappeared from military aviation by the end of World War II, as advancements in propulsion and aeronautical design enabled newer attack/strike aircraft, fighter-bombers, and multirole aircraft types to deliver equal ...

White Army
The White Army (russian: Белая армия, Belaya armiya) or White Guard (russian: Бѣлая гвардія/Белая гвардия, Belaya gvardiya, label=none), also referred to as the Whites or White Guardsmen (russian: Бѣлогвардейцы/Белогвардейцы, Belogvardeytsi, label=none), was a common collective name for the armed formations of the White movement and anti-Soviet governments during the Russian Civil War. They fought against the Red Army of the Bolsheviks. When it was created, the structure of the Russian Army of the Provisional Government period was used, while almost every individual formation had its own characteristics. The military art of the White Army was based on the experience of the First World War, which, however, left a strong imprint on the specifics of the Civil War. History The name "White" is associated with white symbols of the supporters of the pre-revolutionary order, dating back to the time of the French Revolution, ...

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler".

Northern Bombing Group
The Northern Bombing Group consisted of United States Navy and United States Marine Corps squadrons conducting strategic bombing of German U-boat bases along the Belgian coast during World War I. The first United States military unit sent to Europe was the First Aeronautic Detachment of seven naval officers and 122 enlisted men who arrived in France on 5 June 1917. These men became the nucleus of the United States Naval Forces in Europe. They formulated a strategic bombing plan approved by the Secretary of the Navy on 30 April 1918, but chronic difficulties in obtaining aircraft prevented establishment of an effective bombing campaign before the war ended six months later. Background The Imperial German Navy established Flanders U-boat flotillas in March 1915. Type UB and UC submarines were based in Ostend and Zeebrugge with repair yards at Bruges. These coastal submarines operated in the English Channel, along the English coast of the North Sea and in the Western Approaches. U- ...

Great Yarmouth
Great Yarmouth (), often called Yarmouth, is a seaside town and unparished area in, and the main administrative centre of, the Borough of Great Yarmouth in Norfolk, England; it straddles the River Yare and is located east of Norwich. A population of 38,693 in the 2011 Census made it Norfolk's third most populous. Its fishing industry, mainly for herring, shrank after the mid-20th century and has all but ended. North Sea oil from the 1960s supplied an oil-rig industry that services offshore natural gas rigs; more recently, offshore wind power and other renewable energy industries have ensued. Yarmouth has been a resort since 1760 and a gateway from the Norfolk Broads to the North Sea. Holiday-making rose when a railway opened in 1844, bringing easier, cheaper access and some new settlement. Wellington Pier opened in 1854 and Britannia Pier in 1858. Through the 20th century, Yarmouth boomed as a resort, with a promenade, pubs, trams, fish-and-chip shops, theatres, the Pleasu ...

Independent Air Force
The Independent Air Force (IAF), also known as the Independent Force or the Independent Bombing Force and later known as the Inter-Allied Independent Air Force, was a First World War strategic bombing force which was part of Britain's Royal Air Force and was used to strike against German railways, aerodromes, and industrial centres without co-ordination with the Army or Navy. Establishment From late 1916 to early 1917 the Royal Naval Air Service (RNAS) had attempted a co-ordinated series of bombing raids on German-held targets. Whilst the attacks were generally unsuccessful the principle of deep penetration bombing raids against strategic targets was established. General Jan Smuts, a member of the War Cabinet, prepared the Smuts Report which recommended that a separate Air Ministry and Air Force should be set up, independent of the Army and Navy and that a strategic bomber force should be formed whose sole purpose was to attack Germany. Following the perceived success in bombi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cabin Pressurization
Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for passengers and crew flying at high altitudes. For aircraft, this air is usually bled off from the gas turbine engines at the compressor stage, and for spacecraft, it is carried in high-pressure, often cryogenic, tanks. The air is cooled, humidified, and mixed with recirculated air if necessary before it is distributed to the cabin by one or more environmental control systems. The cabin pressure is regulated by the outflow valve. While the first experimental pressurization systems saw use during the 1920s and 1930s, it was not until 1940 that a commercial aircraft would enter service with a pressurized cabin, when the Boeing 307 Stratoliner joined the Transcontinental & Western Air and Pan American Airways fleets. The practice would become widespread a decade later, particularly with the introduction of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dayton-Wright Company
The Dayton-Wright Company was formed in 1917, on the declaration of war between the United States and Germany, by a group of Ohio investors that included Charles F. Kettering and Edward A. Deeds of Dayton Engineering Laboratories Company ( DELCO). Orville Wright lent his name and served as a consultant, but other than that, the location of one of its three factories in the original Wright Company factory buildings in Dayton, Ohio was the only connection to the Wright brothers. In addition to plant 3 (the former Wright Company buildings), Dayton-Wright operated factories in Moraine (plant 1, the main factory) and Miamisburg (plant 2), Ohio. During the course of the war, Dayton-Wright produced about 3,000 DH-4s, as well as 400 Standard SJ-1 trainers. The company was hurt by the reputation of the DH-4s it produced as "flaming coffins" or "flying coffins", although they were not in reality more subject to catching fire than other aircraft, and by scandals it faced.

Curtiss Aeroplane And Motor Company
Curtiss Aeroplane and Motor Company (1909 – 1929) was an American aircraft manufacturer originally founded by Glenn Hammond Curtiss and Augustus Moore Herring in Hammondsport, New York. After significant commercial success in its first decades, it merged with the Wright Aeronautical to form Curtiss-Wright Corporation. History Origin In 1907, Glenn Curtiss was recruited by the scientist Dr. Alexander Graham Bell as a founding member of Bell's Aerial Experiment Association (AEA), with the intent of establishing an aeronautical research and development organization. According to Bell, it was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."Milberry 1979, p 13. In 1909, shortly before the AEA was disbanded, Curtiss partnered with Augustus Moore Herring to form the Herring-Curtiss Company.Gunston 1993, p. 87. It was renamed the Curtiss Aeroplane Company in 1910 and reorganized in 1912 after being taken- ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
