DG-500
The Glaser-Dirks DG-500, and later the DG-505, is a two-seat glider of glass-reinforced plastic and carbon fiber reinforced plastic construction, manufactured in the DG Flugzeugbau GmbH in Bruchsal, Germany. It first flew in 1987. Design The glider is a trainer with an 18-metre wingspan or a high-performance glider with 20 or 22 m span. There are also trailing edge flaps with the exception of the Trainer and Orion variants. The 20m version also has winglets. The fuselage has a single wheel main landing gear which retracts into the lower fuselage. The DG-500/18 is mainly intended for flight training, and is fully aerobatic with +7/-5 g rating. There is also a motorglider version, the DG-500M. The DG-500/22 can carry up to 160 kg of water ballast which is not possible on the trainer version. Since 2004, the latest version of the DG-500 has been built as the "DG-505 Orion" in Slovenia. Past altitude record The DG-500 once held the all-time altitude record for manned glide ...

Schempp-Hirth Duo Discus
The Schempp-Hirth Duo Discus is a high-performance two-seat glider primarily designed for fast cross-country flying, including gliding competitions. Often, it is used for advanced training. Design and development The Duo Discus replaced the Janus as Schempp Hirth's high-performance two-seater trainer. It has a four-piece wing with a span of 20 metres. As with most tandem two-seat gliders, its wing is slightly swept forward so the wing root can be slightly aft to allow the rear pilot an improved view. Although it shares its name with the highly successful Standard Class Discus, any resemblance is only superficial. It first flew in 1993, and is still in production at the factory in Orlican in the Czech Republic. Its best glide ratio was measured as 44:1. An optional 'turbo' retractable two-stroke engine can be specified for extended gliding sessions. As of August 2007, over 500 Duo Discuses have been built. In the U.S. Air Force, it is known as the TG-15A. The chief rival ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organization ...

Mid-engined Aircraft
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive com ...

Motor Gliders
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which ...

1990s German Sailplanes
Year 199 ( CXCIX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was sometimes known as year 952 ''Ab urbe condita''. The denomination 199 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 * Mesopotamia is partitioned into two Roman provinces divided by the Euphrates, Mesopotamia and Osroene. * Emperor Septimius Severus lays siege to the city-state Hatra in Central-Mesopotamia, but fails to capture the city despite breaching the walls. * Two new legions, I Parthica and III Parthica, are formed as a permanent garrison.
