Wackett Warrigal
The Warrigal I and II were Australian aircraft designed by Squadron Leader Lawrence James Wackett and built by the Experimental Section of the Royal Australian Air Force (RAAF) at Randwick, New South Wales, during the late 1920s. They were both single-engined, two-seat biplanes of mixed wood and metal construction. The Warrigal I was the first aircraft designed and built in Australia to an official RAAF specification. Development The Warrigal (an Aboriginal word meaning "wild" or "untamed") I aircraft was designed to meet Air Board specification AC34 for an advanced training aircraft suitable to replace the ageing RAAF Avro 504K fleet. The aircraft was not only required to carry out flight training, but also training in aerial combat, bombing, wireless communication, aerial photography and observation. A mock-up was completed in February 1926 and construction was commenced shortly after. Wackett expected that construction would take around 6 months. However work on the Widgeon ...

Allen & Unwin
George Allen & Unwin was a British publishing company formed in 1911 when Sir Stanley Unwin purchased a controlling interest in George Allen & Co. It went on to become one of the leading publishers of the twentieth century and to establish an Australian subsidiary in 1976. In 1990, Allen & Unwin was sold to HarperCollins and the Australian branch was the subject of a management buy-out. George Allen & Unwin in the UK George Allen & Sons was established in 1871 by George Allen, with the backing of John Ruskin, becoming George Allen & Co. Ltd. in 1911 and then George Allen & Unwin in 1914 as a result of Stanley Unwin's purchase of a controlling interest. Unwin's son Rayner S. Unwin and nephew Philip helped run the company, which published the works of Bertrand Russell, Arthur Waley, Roald Dahl, Lancelot Hogben, and Thor Heyerdahl. It became well known as J. R. R. Tolkien's publisher, some time after publishing the popular children's fantasy novel '' The Hobbit'' in 1937, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seaplane
A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplanes while landplanes could continue to operate.

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airframe
The mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability and cost.Michael C. Y. Niu (1988). ''Airframe Structural Design''. Conmilit Press LTD. History Modern airframe history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs. In 1912 the Deperdussin Monocoque pioneered the light, strong and streamlined monocoque fuselage formed of thin plywood layers over a circular frame, achieving . First World War Many early developments were spurred by military needs during World War I. Well known aircraft from that era include the Dutch designer ...

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 sta ...

Charles Eaton (RAAF Officer)
Charles Eaton, OBE, AFC (21 December 1895 – 12 November 1979) was a senior officer and aviator in the Royal Australian Air Force (RAAF), and later served as a diplomat. Born in London, he joined the British Army upon the outbreak of World War I and saw action on the Western Front before transferring to the Royal Flying Corps in 1917. Posted as a bomber pilot to No. 206 Squadron, he was twice captured by German forces, and twice escaped. Eaton left the military in 1920 and worked in India until moving to Australia in 1923. Two years later he joined the RAAF, serving initially as an instructor at No. 1 Flying Training School. Between 1929 and 1931, he was chosen to lead three expeditions to search for lost aircraft in Central Australia, gaining national attention and earning the Air Force Cross for his "zeal and devotion to duty". In 1939, on the eve of World War II, Eaton became the inaugural commanding officer of No. 12 (General Purpose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Argus (Melbourne)
''The Argus'' was an Australian daily morning newspaper in Melbourne from 2 June 1846 to 19 January 1957, and was considered to be the general Australian newspaper of record for this period. Widely known as a conservative newspaper for most of its history, it adopted a left-leaning approach from 1949. ''The Argus''s main competitor was David Syme's more liberal-minded newspaper, ''The Age''. History The newspaper was originally owned by William Kerr, who was also Melbourne's town clerk from 1851–1856 and had been a journalist at the '' Sydney Gazette'' before moving to Melbourne in 1839 to work on John Pascoe Fawkner's newspaper, the ''Port Phillip Patriot''. The first edition was published on 2 June 1846. The paper soon became known for its scurrilous abuse and sarcasm, and by 1853, after he had lost a series of libel lawsuits, Kerr was forced to sell the paper's ownership to avoid financial ruin. The paper was then published by Edward Wilson. By 1855, it had a daily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
