Polikarpov R-1
The Airco DH.9A is a British single-engined light bomber that was 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bolsheviks
The Bolsheviks, led by Vladimir Lenin, were a radical Faction (political), faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split with the Mensheviks at the 2nd Congress of the Russian Social Democratic Labour Party, Second Party Congress in 1903. The Bolshevik party, formally established in 1912, seized power in Russia in the October Revolution of 1917, and was later renamed the Russian Communist Party, All-Union Communist Party, and ultimately the Communist Party of the Soviet Union. Its ideology, based on Leninism, Leninist and later Marxism–Leninism, Marxist–Leninist principles, became known as Bolshevism. The origin of the RSDLP split was Lenin's support for a smaller party of professional revolutionaries, as opposed to the Menshevik desire for a broad party membership. The influence of the factions fluctuated in the years up to 1912, when the RSDLP formally split in two. The political philosophy of the Bolsheviks was based on the Leninist pr ...

White Army
The White Army, also known as the White Guard, the White Guardsmen, or simply the Whites, was a common collective name for the armed formations of the White movement and Anti-Sovietism, anti-Bolshevik governments during the Russian Civil War. They fought against the Red Army of Russian Soviet Federative Socialist Republic, Soviet Russia. When it was created, the structure of the Russian Army (1917), Russian Army during the period of the Russian Provisional Government 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 World War I, First World War, which, however, left a strong imprint on the specifics of the Russian Civil War. History The name "White" is associated with white symbols of the supporters of the Ancien Régime, pre-revolutionary order, dating back to the time of the French Revolution, in contrast to the name of the Red Guards (Russia), Red Guard detachments, and then th ...

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 Continental Europe (France) 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 aviation 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 S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Yarmouth
Great Yarmouth ( ), often called Yarmouth, is a seaside resort, seaside town which gives its name to the wider Borough of Great Yarmouth in Norfolk, England; it straddles the River Yare and is located east of Norwich. 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. Holidaymaking 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 Great Yarmouth Pleasure Beach, Pleasure Beach, the Sea Life Centres, Sea Life Centre, the Great Yarmouth Hi ...

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 aircraft cabin, cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for humans flying at high altitudes. For aircraft, this air is usually Bleed air, bled off from the gas turbine, gas turbine engines at the compressor stage, and for spacecraft, it is carried in high-pressure, often liquid oxygen, cryogenic, tanks. The air is cooled, humidified, and mixed with recirculated air by one or more Environmental control system (aircraft), environmental control systems before it is distributed to the cabin. The first experimental pressurization systems saw use during the 1920s and 1930s. In the 1940s, Boeing 307 Stratoliner, the first commercial aircraft with a pressurized cabin entered service. The practice would become widespread a decade later, particularly with the introduction of the British de Havilland Comet jetliner in 1949. However, South African Airways Flight 201 ...

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
The Curtiss Aeroplane and Motor Company (1909–1929) was an American aircraft manufacturer originally founded by Glenn Curtiss, 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
