Airspeed Ferry
The Airspeed AS.4 Ferry was three-engined ten-seat biplane airliner designed and built by the British aircraft manufacturer Airspeed Limited. It was the company's first powered aircraft to be produced. It was proposed for development in April 1931, shortly following Airspeed's founding. The Ferry was designed specifically for Alan Cobham's ''National Aviation Day'' events, performing 'air-experience' flights for the general public. On 5 April 1932, the prototype performed its maiden flight. Only four examples were produced at the company's facilities in York during the early 1930s. Two aircraft served with the Royal Air Force during the opening years of the Second World War, although largely being used as instructional airframes. Development The origins of the Airspeed Ferry can be traced back to the company's first post-formation board meeting, held on 17 April 1931. Aviation innovator and Airspeed director Sir Alan Cobham sought a compact multi-engined airliner to perform 'a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is i ...

Himalaya Air Transport And Survey Company Limited
The Himalayas, or Himalaya (; ; ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo–Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas.

RAF Halton
Royal Air Force Halton, or more simply RAF Halton, is one of the largest Royal Air Force stations in the United Kingdom. It is located near the village of Halton near Wendover, Buckinghamshire. The site has been in use since the First World War but is due to close by December 2027. The Queen Consort is the Honorary Air Commodore of RAF Halton. History The first recorded military aviation at Halton took place in 1913 when the then owner of the Halton estate, Alfred de Rothschild, invited No 3 Squadron of the Royal Flying Corps to conduct manoeuvres on his land. Following a gentlemen's agreement between Rothschild and Lord Kitchener, the estate was used by the British Army throughout the First World War. In 1916 the Royal Flying Corps moved its air mechanics school from Farnborough, Hampshire to Halton, and in 1917, the school was permanently accommodated in workshops built by German PoWs. The estate was purchased by the British Government for the nascent Royal Air Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impressment
Impressment, colloquially "the press" or the "press gang", is the taking of men into a military or naval force by compulsion, with or without notice. European navies of several nations used forced recruitment by various means. The large size of the British Royal Navy in the Age of Sail meant impressment was most commonly associated with Great Britain and Ireland. It was used by the Royal Navy in wartime, beginning in 1664 and during the 18th and early 19th centuries as a means of crewing warships, although legal sanction for the practice can be traced back to the time of Edward I of England. The Royal Navy impressed many merchant sailors, as well as some sailors from other, mostly European, nations. People liable to impressment were "eligible men of seafaring habits between the ages of 18 and 55 years". Non- seamen were sometimes impressed as well, though rarely. In addition to the Royal Navy's use of impressment, the British Army also experimented with impressment from 1778 to 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of whic ...
