Schempp-Hirth HS-3 Nimbus
The Schempp-Hirth HS-3 Nimbus was a prototype glider built by Klaus Holighaus. The HS-3 Nimbus was a high performance single-seater. Holighaus designed and built this prototype glider in his spare time with assistance from Schempp-Hirth. Strictly speaking, it is not a Schempp-Hirth glider but rather a glider built at Schempp-Hirth. It employed the same fuselage as the Open Class Cirrus and a similar tail, but had an entirely new wing, high-set and in three segments adding up to a span. The prototype first flew in January 1969. The Nimbus had a rudder far too small for an aircraft of its size, leading to very unfavourable control characteristics; After the pilot applied full aileron and rudder inputs, the glider continued to fly straight ahead for several seconds before suddenly dropping a wing, requiring full opposite controls to recover. No air brakes were fitted and it was an exceptionally difficult glider to land. It was damaged several times in overshoots. However, it ha ...

Schempp-Hirth Aircraft
Schempp-Hirth Flugzeugbau GmbH is a glider (sailplane), glider List of gliders, 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 configurat ...

1960s German Sailplanes
Year 196 ( CXCVI) was a leap year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 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.

Schempp-Hirth Nimbus-2
The Schempp-Hirth Nimbus-2 is an Open Class glider built by Schempp-Hirth during the 1970s. The Nimbus-2 first flew in April 1971 and a total of over 240 examples of all subtypes have been built until the beginning of the 1980s. It replaced the Schempp-Hirth Cirrus. Design and development Loosely based on the original Nimbus HS-3 prototype, the production version that eventually surfaced as the Nimbus-2 was a very different glider with many improvements over the problematic prototype. The wing was shortened to 20.3 metres and was built in four sections to make it easier to rig and transport. It received Schempp-Hirth air brakes fitted in the upper surfaces and a tail braking-parachute, plus camber-changing flaps. It had an all-flying T-tail similar to the Standard Cirrus as well as the general layout of its fuselage. The Nimbus-2 was successful in competitions, twice winning the Open Class in World Gliding Championships: Göran Ax (Sweden) in 1972 and George Moffat (USA) ...

Akaflieg Darmstadt D36
Akaflieg is an abbreviation for ''Akademische Fliegergruppe'', groups of aeronautical engineering students from individual German universities of technology and Technische Hochschulen, pre and postwar, who design aircraft, often gliders. History Otto Lilienthal published his book ''Der Vogelflug als Grundlage der Fliegekunst (Birdflight as the Basis of Aviation)'' in 1889. This described the basics of modern aerodynamics and aircraft construction. Lilienthal then made many successful flights starting in 1891. However attention then shifted to powered flight after World War I. Gliding re-emerged as a sport after the war because the building of powered aircraft was restricted in Germany by the Treaty of Versailles. The main originator of the gliding movement was Oskar Ursinus, who in 1920 organised the first contest, known as the Rhön-Contest, on the Wasserkuppe. Thereafter the contest was held annually. Students of Technische Hochschulen brought gliders which they had develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marfa, Texas
Marfa is a city in the high desert of the Trans-Pecos in far West Texas, United States, between the Davis Mountains and Big Bend National Park, at an elevation of 4685 feet. It is the county seat of Presidio County, Texas, Presidio County. The city was founded in the early 1880s as a water stop. The population of Marfa peaked in the 1930s and as of the 2020 United States Census the population is 1,788. Today Marfa is a tourist destination and a major center for Minimalism (visual arts), minimalist art. Major attractions include Building 98, the Chinati Foundation, and the Marfa lights. History Marfa was founded in the early 1880s as a railroad water stop. The town was named "Marfa" (Russian for "Martha") at the suggestion of the wife of a railroad executive. Although some historians have hypothesized that the name came from a character in Fyodor Dostoevsky's novel ''The Brothers Karamazov'', Marfa was actually named after Marfa Strogoff, a character in Jules Verne's novel ''Mi ...

World Gliding Championships
The World Gliding Championships (WGC) is a gliding competitions, gliding competition held roughly every two years by the FAI Gliding Commission. The dates are not always exactly two years apart, often because the contests are always held in the summer in either the Southern Hemisphere or Northern Hemisphere. History Gliding had been a demonstration sport at the 1936 Summer Olympics and was due to become an official Olympic sports, Olympic sport in the Helsinki Games in 1940 Summer Olympics, 1940. However, since the Second World War, gliding has not featured in the Olympic Games, Olympics, and so the World Championships are the highest level in the sport. There are now contests for six Glider competition classes, classes of glider (sailplane), 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 fol ...

Glide Ratio
In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under given flight conditions. The L/D ratio for any given body will vary according to these flight conditions. For an aerofoil wing or powered aircraft, the L/D is specified when in straight and level flight. For a glider it determines the glide ratio, of distance travelled against loss of height. The term is calculated for any particular airspeed by measuring the lift generated, then dividing by the drag at that speed. These vary with speed, so the results are typically plotted on a 2-dimensional graph. In almost all cases the graph forms a U-shape, due to the two main components of drag. The L/D may be calculated using computational fluid dynamics or computer simulation. It is measured empirically by testing in a wind tunnel or in free flight ...

Air Brake (aircraft)
In aeronautics, air brakes, or speed brakes, are a type of flight control surface used on an aircraft to increase the drag on the aircraft. When extended into the airstream, air brakes cause an increase in the drag on the aircraft. When not in use, they conform to the local streamlined profile of the aircraft in order to help minimize drag. Air brakes differ from spoilers in that air brakes are designed to increase drag while making little change to lift, whereas spoilers reduce the lift-to-drag ratio and require a higher angle of attack to maintain lift, resulting in a higher stall speed. However, flight spoilers are routinely referred to as "speed brakes" on transport aircraft by pilots and manufacturers, despite significantly reducing lift. History In the early decades of powered flight, air brakes were flaps mounted on the wings. They were manually controlled by a lever in the cockpit, and mechanical linkages to the air brake. Another early type of air brake, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
