Gloster Gamecock
The Gloster Gamecock was a biplane fighter aircraft, fighter designed and produced by the British aircraft manufacturer Gloster Aircraft Company, Gloster. The Gamecock was a development of the earlier Gloster Grebe, Grebe Mk III, an early interwar fighter procured by the Royal Air Force (RAF). Work on the type commenced in 1924 as a response to Air Ministry List of Air Ministry specifications#1920–1929, Specification 37/23. The principal difference between the two aircraft was the adoption of the Bristol Jupiter radial engine for the Gamecock. in the place of the somewhat unreliable Armstrong Siddeley Jaguar. Various structural improvements were made to the fuselage, the armament was also revised to include internally-mounted machine guns. On 22 February 1925, the prototype Gamecock performed its maiden flight. Evaluation flights at RAF Martlesham Heath resulted in considerable praise for the aircraft; few changes were made as a result. During September 1925, the Air Ministry ...

RAF Martlesham Heath
Royal Air Force Martlesham Heath or more simply RAF Martlesham Heath is a former Royal Air Force station located southwest of Woodbridge, Suffolk, England. It was active between 1917 and 1963, and played an important role in the development of airborne radar. History RFC/RAF prewar use Martlesham Heath was first used as a Royal Flying Corps airfield during the First World War. In 1917 it became home to the Aeroplane Experimental Unit, RFC which moved from Upavon with the site named as the Aeroplane Experimental Station, next became the Aeroplane Experimental Establishment (Home) in 1920 and then the Aeroplane and Armament Experimental Establishment (A&AEE) in 1924. The A&AEE carried the evaluation and testing of many of the aircraft types and much of the armament and other equipment that would later be used during the Second World War. No. 22 Squadron RAF and No. 15 Squadron RAF were present during the 1920s. No. 64 arrived in the 1930s. RAF Fighter Command use The A&AEE ...

Finnish Language
Finnish (endonym: or ) is a Finnic languages, Finnic language of the Uralic languages, Uralic language family, spoken by the majority of the population in Finland and by ethnic Finns outside of Finland. Finnish is one of the two official languages of Finland, alongside Swedish language, Swedish. In Sweden, both Finnish and Meänkieli (which has significant mutual intelligibility with Finnish) are official minority languages. Kven language, Kven, which like Meänkieli is mutually intelligible with Finnish, is spoken in the Norway, Norwegian counties of Troms and Finnmark by a minority of Finnish descent. Finnish is morphological typology, typologically agglutinative language, agglutinative and uses almost exclusively Suffix, suffixal affixation. Nouns, adjectives, pronouns, Numeral (linguistics), numerals and verbs are inflection, inflected depending on their role in the Sentence (linguistics), sentence.

Aeroelasticity
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: ''static aeroelasticity'' dealing with the static or steady state response of an elastic body to a fluid flow, and ''dynamic aeroelasticity'' dealing with the body's dynamic (typically vibrational) response. Aircraft are prone to aeroelastic effects because they need to be lightweight while enduring large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the twist of a wing which further increases forces; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases reverses, the control effectiveness; and # flutter which is uncontained vibration that can lead to the destr ...

Spin (flight)
In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a crash may require a specific and counter-intuitive set of actions. A spin differs from a spiral dive, in which neither wing is stalled ...

RAF Henlow
Royal Air Force Henlow or more simply RAF Henlow is a Royal Air Force station in Bedfordshire, England, equidistant from Bedford, Luton and Stevenage. It houses the RAF Centre of Aerospace Medicine and the Joint Arms Control Implementation Group (JACIG), and was home to the Signals Museum, which closed in June 2024. It formerly hosted light aircraft flying and 616 Volunteer Gliding Squadron. The Ministry of Defence announced on 6 September 2016 that the base is set to be closed. As of January 2024, the closure and disposal of the station is expected to take place from 2026. Flying activity ceased in July 2020. History Henlow was chosen as a military aircraft repair depot in 1917 and was built by MacAlpine during 1918. Four Belfast Hangars were built and are now listed buildings. Henlow Camp, a civilian settlement, grew up around the base at that time. Originally a repair depot for aircraft from the Western Front, the Station officially opened on 18 May 1918 when Lt Col Ro ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. H ...

Asbestos
Asbestos ( ) is a group of naturally occurring, Toxicity, toxic, carcinogenic and fibrous silicate minerals. There are six types, all of which are composed of long and thin fibrous Crystal habit, crystals, each fibre (particulate with length substantially greater than width) being composed of many microscopic "fibrils" that can be released into the atmosphere by Abrasion (mechanical), abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer. As a result of these health effects, asbestos is considered a serious Health hazard, health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent Thermal insulation, thermal and In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...
