De Havilland Australia DHA-G2
The de Havilland Australia DHA-G2 was a Second World War Australian transport glider based on the earlier prototype DHA-G1. Only two prototype G1 and six production G2 gliders were built. Design and development The G1 glider was designed to meet a Royal Australian Air Force (RAAF) requirement for a transport glider to specification 5/42. Two prototype gliders, sometimes known as ''Experimental Glider 1'', were ordered from de Havilland Australia (DHA). As DHA were already committed to build Tiger Moth basic trainers and Dragon navigation trainers, most of the work was to be done by subcontractors, with much of the build work on the two prototypes being carried out on the fifth floor of a Mill in Camperdown, Sydney.Issacs ''Air International'' July 1976, p. 23. It was a high-wing cantilever monoplane of all wooden construction, making extensive use of plywood. It used the cockpit canopy of the DH.84 Dragon, but was otherwise an original design. The aircraft's undercarriage us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Glider
Military gliders (an offshoot of common gliders) have been used by the militaries of various countries for carrying troops ( glider infantry) and heavy equipment to a combat zone, mainly during the Second World War. These engineless aircraft were towed into the air and most of the way to their target by military transport planes, e.g., C-47 Skytrain or Dakota, or bombers relegated to secondary activities, e.g., Short Stirling. Most military gliders do not soar, although there were attempts to build military sailplanes as well, such as the DFS 228. Once released from the tow craft near the front, they were to land on any convenient open terrain close to the target, hopefully with as little damage to the cargo and crew as possible as most landing zones (LZ) were far from ideal. The one-way nature of the missions meant that they were treated as semi-expendable leading to construction from common and inexpensive materials such as wood. Most nations seriously attempted to recover as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite ...

1940s Military Gliders
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

Douglas C-47 Skytrain
The Douglas C-47 Skytrain or Dakota ( RAF, RAAF, RCAF, RNZAF, and SAAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II and remained in front-line service with various military operators for many years.Parker 2013, pp. 13, 35, 37, 39, 45-47. Design and development The C-47 differed from the civilian DC-3 by way of numerous modifications, including being fitted with a cargo door, hoist attachment and strengthened floor - along with a shortened tail cone for glider-towing shackles, and an astrodome in the cabin roof.Wilson, Stewart. ''Aircraft of WWII''. Fyshwick, ACT, Australia: Aerospace Publications Pty Ltd., 1998. . During World War II, the armed forces of many countries used the C-47 and modified DC-3s for the transport of troops, cargo, and wounded. The U.S. naval designation was R4D. More than 10,000 aircraft were produced in Long Beach and Santa Monica, Califo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

De Havilland Australia
de Havilland Aircraft Pty Ltd (DHA) was part of de Havilland, then became a separate company. It acquired the Commonwealth Aircraft Corporation in 1985 and was purchased by Boeing in 2000 and merged with the Boeing owned AeroSpace Technologies of Australia (formerly the Government Aircraft Factories) to become Hawker de Havilland Aerospace Pty Ltd. In 2009, the name was changed to Boeing Aerostructures Australia (BAA) and is a subsidiary of Boeing Australia Ltd. Early years and WWII In March 1927 the de Havilland Aircraft Company established DHA in Melbourne, its first overseas subsidiary. Its founder was Hereward de Havilland. DHA was set up to sell de Havilland products in Australia, to assemble aircraft that had been sold, and to provide repair and spare parts services. In 1930 DHA relocated to Mascot aerodrome in Sydney. Prior to World War II DHA did not undertake any production of aircraft (although de Havilland designs were licence-built by other Australian organ ...

Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In ...
