Schempp-Hirth Ventus-2
The Schempp-Hirth Ventus-2 is a sailplane produced by Schempp-Hirth since 1994. It replaced the highly successful Schempp-Hirth Ventus. Design and development The Ventus-2a and 2b are 15 metre sailplanes. The 'a' version has a narrow fuselage and the wider fuselage version is called the 2b. Winglets are used with these models. The 18 metre span Ventus-2c was introduced in 1995 and was almost an entirely different aircraft with a different fuselage and wings, but it has the option of shorter tips with winglets to fly as a 15-metre sailplane. From 2003 the Schempp-Hirth Discus-2 fuselage was used for all versions, which now have the designations 2ax, 2bx and 2cx. Flight tests in 1996 showed that the 15 metre version had a glide angle of 46:1 but only after considerable work on sealing gaps and by using turbulators. The narrow fuselage Ventus-2a has been highly successful in competitions with consecutive World Championship wins from 1995 to 2003. A narrow fuselage versio ...

World Gliding Championships
The World Gliding Championships (WGC) is a gliding competition held every two years or so by the FAI Gliding Commission. The dates are not always exactly two years apart, often because the contests are sometimes held in the summer in the Southern Hemisphere. History Gliding had been a demonstration sport at the 1936 Summer Olympics and was due to become an official Olympic sport in the Helsinki Games in 1940. However, since the Second World War, gliding has not featured in the Olympics, and so the World Championships are the highest level in the sport. There are now contests for six classes of glider and so in recent years the Championships have been divided between two locations. The women's, junior, grand prix and aerobatic events are also held separately. Each of the following entries give the year and location of the contest followed by the winner of each class, nationality and the glider used. A list of future events is available here World Grand Prix Gliding Champ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Aircraft
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines. Crewed flights in an electrically powered airship go back to the 19th century, and to 1917 for a tethered helicopter. Electrically powered model aircraft have been flown at least since the 1970s, preceding the small unmanned aerial vehicles (UAV) or drones used today. Small UAS could be used for parcel deliveries, and larger ones for long-endurance applications: aerial imagery, surveillance, telecommunications. The first crewed free flight by an electrically powered aeroplane, the MB-E1, was made in 1973, and most crewed electric aircraft today are still only experimental prototypes. Between 2015 and 2016, Solar Impulse 2 completed a circu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft First Flown In 1994
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air b ...

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.

Schempp-Hirth Aircraft
Schempp-Hirth Flugzeugbau GmbH is a glider manufacturer based in Kirchheim unter Teck, Germany. History Martin Schempp founded his own company in Göppingen in 1935, with the assistance of Wolf Hirth. The company was initially called "Sportflugzeugbau Göppingen Martin Schempp". In 1938, Wolf Hirth, mainly responsible for the design work, officially became a partner in the company, which then became "Sportflugzeugbau Schempp-Hirth". The company relocated to Kirchheim unter Teck the same year. The company's first product was the Göppingen Gö 1 ''Wolf'' glider, conceived as a rival to the ubiquitous Grunau Baby, but real success came with the Göppingen Gö 3 ''Minimoa'' the same year. During World War II, the company built DFS Habicht training gliders, as well as tailplane assemblies for the Messerschmitt Bf 109. The company also built a research aircraft, the Göppingen Gö 9 to investigate Claude Dornier's rear-mounted " pusher" propeller plans. With its cruciform ta ...

Schempp-Hirth Ventus 3
The Schempp-Hirth Ventus-3 is a sailplane produced by Schempp-Hirth. It replaces the highly successful Schempp-Hirth Ventus-2. Design and development It was announced at the AERO Friedrichshafen in April 2015 where a mock-up was suspended from the ceiling of the exhibition hall. The prototype flew on 29 January 2016 at Flugplatz Hahnweide at Kirchheim unter Teck in Germany. Production of the first seven turbo Ventus 3T started on 28 April 2016. These competed in the 2017 World Gliding Championships and the 2017 European Gliding Championships. In the latter competition, pilots with Ventus 3T took the first three places in the 18m Class. A Ventus 3T also took first place at the World Championships at Hos%C3%ADn in 2018. Two sizes of fuselage are now available, Sport and Performance; the latter is larger. The Sport fuselage is available as a pure glider, or with a turbo sustaining engine, or a front-end electric sustaining (FES) engine. Currently the larger fuselage is only avail ...

Front Electric Sustainer
Front electric sustainer (FES) is a propulsion system for gliders that uses an electric motor powered by batteries and a foldable propeller. It is produced by LZ Design d.o.o. in Logatec, Slovenia. The system uses a 22 kW compact outrunner brushless DC electric motor located in the nose of the sailplane. Power is provided by two lithium-ion battery packs. Lighter gliders are able to self-launch with FES. Heavier gliders can use it as a sustainer system, i.e. climb and cruise sufficiently high and far to avoid an out-landing. Although gliders with FES have a shorter range (70–100 km) under power than gliders with two-stroke gasoline sustainer engines (10 litres at 8.5 L/h at 100 km/h = 120 km) or jet sustaining engines (150–200 km), the electric motor can be expected to start reliably provided there is sufficient energy in the batteries. The one-metre diameter propeller is made of carbon fibre and folds across the nose. It opens using centrifugal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gliding
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
