Airco DH.6
The Airco DH.6 was a British military Trainer (aircraft), trainer biplane used by the Royal Flying Corps during the First World War. Known by various nicknames, including the "Clutching hand" and "Skyhook", many survived to be used as a civil light aircraft in the postwar era. Design and development The DH.6 was specifically designed as a military trainer, at a time when it was usual for obsolete service types to be used in this role. Geoffrey de Havilland seems to have had two design criteria in mind.Jackson 1962, p. 53. The first was that it should be inexpensive and easy to build, and above all, simple to repair after the mishaps common in training units. The top and bottom wings were square-cut and interchangeable, hence roundels often located in unusual positions. They were heavily Camber (aerodynamics), cambered, and braced with cables rather than streamlined wires. On the original version of the type there was no Stagger (aeronautics), stagger. Even the fin and rudder, on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airco
The Aircraft Manufacturing Company Limited (Airco) was an early United Kingdom, British aircraft manufacturer. Established during 1912, it grew rapidly during the First World War, referring to itself as the largest aircraft company in the world by 1918. Airco produced many thousands of aircraft for both the British and Allied military air wings throughout the war, including fighter aircraft, fighters, trainer aircraft, trainers and medium bomber, bombers. The majority of the company's aircraft were designed in-house by Airco's chief designer Geoffrey de Havilland. Airco established the first airline in the United Kingdom, Aircraft Transport and Travel Limited, which operated as a subsidiary of Airco. On 25 August 1919, it commenced the world's first regular daily international service. Following the end of the war, the company's fortunes rapidly turned sour. The interwar period was unfavourable for aircraft manufacturers largely due to a glut of surplus aircraft from the war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anti-submarine
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Naval Air Service
The Royal Naval Air Service (RNAS) was the air arm of the Royal Navy, under the direction of the Admiralty's Air Department, and existed formally from 1 July 1914 to 1 April 1918, when it was merged with the British Army's Royal Flying Corps to form the Royal Air Force (RAF), the world's first independent air force. It was replaced by the Fleet Air Arm, initially consisting of those RAF units that normally operated from ships, but emerging as a separate unit similar to the original RNAS by the time of World War 2. Background In 1908, the British Government recognised the military potential of aircraft. The Prime Minister of the United Kingdom, Prime Minister, H. H. Asquith, approved the formation of an "Advisory Committee for Aeronautics" and an "Aerial Sub-Committee of the Committee of Imperial Defence". Both committees were composed of politicians, British Army, army officers and Royal Navy officers. On 21 July 1908 Captain Reginald Bacon, who was a member of the Aerial Na ...

Avro 504
The Avro 504 was a First World War biplane aircraft made by the Avro aircraft company and under licence by others. Production during the war totalled 8,970 and continued for almost 20 years, making it the most-produced aircraft of any kind that served in any military capacity during the First World War. More than 10,000 were built from 1913 until production ended in 1932. Design and development First flown from Brooklands by Fred "Freddie" Raynham on 18 September 1913,Jackson 1990, p.52. powered by an Gnome Lambda seven-cylinder rotary engine, the Avro 504 was a development of the earlier Avro 500, designed for training and private flying.

Combat Stress Reaction
Combat stress reaction (CSR) is acute behavioral disorganization as a direct result of the trauma of war. Also known as "combat fatigue", "battle fatigue", or "battle neurosis", it has some overlap with the diagnosis of acute stress reaction used in civilian psychiatry. It is historically linked to shell shock and can sometimes precurse post-traumatic stress disorder. Combat stress reaction is an acute reaction that includes a range of behaviors resulting from the stress of battle that decrease the combatant's fighting efficiency. The most common symptoms are fatigue, slower reaction times, indecision, disconnection from one's surroundings, and the inability to prioritize. Combat stress reaction is generally short-term and should not be confused with acute stress disorder, post-traumatic stress disorder, or other long-term disorders attributable to combat stress, although any of these may commence as a combat stress reaction. The US Army uses the term/acronym COSR (Combat Stress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biggles
James Bigglesworth, nicknamed "Biggles", is a fictional pilot and adventurer, the title character and hero of the ''Biggles'' series of adventure books, written for young readers by W. E. Johns (1893–1968). Biggles made his first appearance in the story ''The White Fokker'', published in the first issue of ''Popular Flying'' magazine and again as part of the first collection of Biggles stories, ''The Camels Are Coming'' (both 1932). Johns continued to write "Biggles books" until his death in 1968. The series eventually included nearly a hundred volumes – novels as well as short story collections – most of the latter with a common setting and time. The chronology of the canon, spanning both world wars, set up certain inconsistencies over the unavoidable ageing of Biggles and his friends. Also later editions had to be somewhat edited in line with changing norms of acceptability, especially regarding race, and in view of the pre-teenage readership who increasingly favoured ...

Robert R
Robert Lee Rayford (February 3, 1953 – May 15 1969), sometimes identified as Robert R. due to his age, was an American teenager from Missouri who has been suggested to represent the earliest confirmed case of HIV/AIDS in North America based on evidence which was published in 1988 in which the authors claimed that medical evidence indicated that he was "infected with a virus closely related or identical to human immunodeficiency virus type 1." Rayford died of pneumonia, but his other symptoms baffled the doctors who treated him. A study published in 1988 reported the detection of antibodies against HIV. Results of testing for HIV genetic material were reported once at a scientific conference in Australia in 1999; however, the data has never been published in a peer-reviewed medical or scientific journal. Background Robert Rayford was born on February 3, 1953, in St. Louis, Missouri to Constance Rayford (September 12, 1931 – April 3, 2011) and Joseph Benny Bell (March 24, 1 ...

School Of Special Flying
A school is an educational institution designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the '' Regional terms'' section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university. In addition to these core schools, students in a given country may also attend schools before and after primary (elementary in the U.S.) and secondary (middle school in the U.S.) education. Kindergarten or preschool provide some schooling to very young children (typically ages 3–5). University, vocational school, college or seminary may be availabl ...

Curtiss JN-4
The Curtiss JN "Jenny" was a series of biplanes built by the Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. Although the Curtiss JN series was originally produced as a training aircraft for the US Army, the "Jenny" (the common nickname derived from "JN") continued after World War I as a civil aircraft, as it became the "backbone of American postwar ivilaviation". Thousands of surplus Jennys were sold at bargain prices to private owners in the years after the war and became central to the barnstorming era that helped awaken the US to civil aviation through much of the 1920s. Design and development Curtiss combined the best features of the model J and model N trainers, built for the US Army and US Navy, and began producing the JN or "Jenny" series of aircraft in 1915. Curtiss built only a limited number of the JN-1 and JN-2 biplanes. The design was commissioned by Glenn Curtiss from Englishman Benjamin Douglas Thomas, formerl ...

Gloster Aircraft
The Gloster Aircraft Company was a British aircraft manufacturer from 1917 to 1963. Founded as the Gloucestershire Aircraft Company Limited during the First World War, with the aircraft construction activities of H H Martyn & Co Ltd of Cheltenham, England it produced fighters during the war. It was renamed later as foreigners found 'Gloucestershire' difficult to pronounce. It later became part of the Hawker Siddeley group and the Gloster name disappeared in 1963. Gloster designed and built several fighters that equipped the British Royal Air Force (RAF) during the interwar years including the Gladiator, the RAF's last biplane fighter. The company built most of the wartime production of Hawker Hurricanes and Hawker Typhoons for their parent company Hawker Siddeley while its design office was working on the first British jet aircraft, the E.28/39 experimental aircraft. This was followed by the Meteor, the RAF's first jet-powered fighter and the only Allied jet fighter to be pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
