NSU Delphin III
The NSU Delphin III streamliner motorcycle set the motorcycle land speed record in 1956. Wilhelm Herz rode the machine to at Bonneville Speedway in Utah, to break 200 mph (320 km/h) for the first time. Its Motorcycle fairing, fairing, designed in a wind tunnel at University of Stuttgart (then Stuttgart Technical College), gave it a drag coefficient of 0.19. The same engine powered Herz to a 1951 world speed record, with a less efficient frame/fairing, the ''Delphin I''. The engine used an unusual rotary supercharger related to NSU's eventual development of the Wankel engine. In the supercharger, both a trochoidal inner rotor and epitrochoidal outer rotor spun around a stationary shaft.

Motorcycle Fairing
A motorcycle fairing is a shell placed over the frame of a motorcycle, especially racing motorcycles and sport bikes, to deflect wind and reduce air drag. The secondary functions are the protection of the rider from airborne hazards and wind-induced hypothermia and of the engine components in the case of an accident. A motorcycle windshield will usually be integrated into the design of the fairing.Tony Foale, ''Motorcycle Handling and Chassis Design'', , Chapter 5: "Aerodynamics" The major benefit of a fairing on sport touring and touring motorcycles is a reduction in aerodynamic drag, which allows for reduced fuel consumption and permits higher speeds at lower engine rpm, which in turn increases engine life. A motorcycle may have a front fairing, a rear fairing, a belly fairing, or any combination of these. Alternatively, a single fairing may partially or fully enclose the entire motorcycle, and may even enclose the rider. History The importance of streamlining was known very ...

Technikmuseum Speyer
The Technik Museum Speyer is a technology museum in Speyer (Rhineland-Palatinate), Germany.

Epitrochoid
In geometry, an epitrochoid ( or ) is a roulette traced by a point attached to a circle of radius rolling around the outside of a fixed circle of radius , where the point is at a distance from the center of the exterior circle. The parametric equations for an epitrochoid are: :\begin & x (\theta) = (R + r)\cos\theta - d\cos\left(\theta\right) \\ & y (\theta) = (R + r)\sin\theta - d\sin\left(\theta\right) \end The parameter is geometrically the polar angle of the center of the exterior circle. (However, is not the polar angle of the point (x(\theta),y(\theta)) on the epitrochoid.) Special cases include the limaçon with and the epicycloid with . The classic Spirograph toy traces out epitrochoid and hypotrochoid curves. The paths of planets in the once popular geocentric system of deferents and epicycles are epitrochoids with d>r, for both the outer planets and the inner planets. The orbit of the Moon, when centered around the Sun, approximates an epitrochoid. The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an eccentric (mechanism), eccentric Pistonless rotary engine, rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor spins inside a figure-eight-like epitrochoidal housing around a fixed gear. The midpoint of the rotor moves in a circle around the output shaft, rotating the shaft via a Cam (mechanism), cam. In its basic gasoline-fuelled form, the Wankel engine has lower thermal efficiency and higher exhaust emissions relative to the Four-stroke engine, four-stroke reciprocating engine. This thermal inefficiency has restricted the Wankel engine to limited use since its introduction in the 1960s. However, many disadvantages have mainly been overcome ...

University Of Stuttgart
The University of Stuttgart () is a research university located in Stuttgart, Germany. It was founded in 1829 and is organized into 10 faculties. It is one of the oldest technical universities in Germany with programs in civil, mechanical, industrial and electrical engineering, among others. It is a member of TU9, an incorporated society of the largest and most notable German institutes of technology. History From 1770 to 1794, the Karlsschule was the first university in Stuttgart. The University of Hohenheim in Stuttgart-Hohenheim, founded in 1818 and Stuttgart's oldest still existing university, is not related to the University of Stuttgart, except for some joint activities. What is now the University of Stuttgart was founded in 1829, and celebrated its 175th anniversary in 2004. Because of the increasing importance of the technical sciences and instruction in these fields, from 1876 the university was known as the Technische Hochschule Stuttgart (Stuttgart Institute of ...

Wind Tunnel
A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". The experiment is conducted in the test section of the wind tunnel and a complete tunnel configuration includes air ducting to and from the test section and a device for keeping the air in motion, such as a fan. Wind tunnel uses include assessing the effects of air on an aircraft in flight or a ground vehicle moving on land, and measuring the effect of wind on Building, buildings and bridges. Wind tunnel test sections range in size from less than a foot across, to over , and with air speeds from a light breeze to hypersonic. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautical research, as part of the effort to develop heavier-than-air flying machines. The wind tunnel reversed the usual situation. Instead of the air standing still and an aircraft moving, an object would be held still and the air moved around it. ...

Bonneville Speedway
Bonneville Speedway (also known as the Bonneville Salt Flats Race Track) is an area of the Bonneville Salt Flats northeast of Wendover, Utah, that is marked out for motor sports. It is particularly noted as the venue for numerous land speed records. The Bonneville Salt Flats Race Track is listed on the National Register of Historic Places. The salt flats were first used for motor sports in 1912, but did not become truly popular until the 1930s when Ab Jenkins and Malcolm Campbell, Sir Malcolm Campbell competed to set land speed records. A reduction of available racing surface and salt thickness has led to the cancellation of events at Bonneville, such as Speed Week in 2014 and 2015. Available racing surface is much reduced with just available instead of the courses traditionally used for Speed Week. Track layouts Historically, the speedway was marked out by the Utah Department of Transportation at the start of each summer. Originally, two tracks were prepared; a long straig ...

Deutsches Museum
The Deutsches Museum (''German Museum'', officially (English: ''German Museum of Masterpieces of Science and Technology'')) in Munich, Germany, is the world's largest museum of science museum, science and technology museum, technology, with about 125,000 exhibited objects from 50 fields of science and technology. It receives about 1.5 million visitors per year. The museum was founded on 28 June 1903, at a meeting of the Verein Deutscher Ingenieure, Association of German Engineers (VDI) as an initiative of Oskar von Miller. It is the largest museum in Munich. For a period of time the museum was also used to host pop and rock concerts including The Who, Jimi Hendrix and Elton John. Museumsinsel The main site of the Deutsches Museum is a small island in the Isar river, which had been used for rafting wood since the Middle Ages. The island did not have any buildings before 1772 because it was regularly flooded prior to the building of the Sylvensteinspeicher. In 1772 the ...

Wilhelm Herz
Wilhelm Herz (18 January 1912 – 5 January 1998) was a German professional motorcycle racer and land speed racer. After his motorcycle racing career, he became the manager for the Hockenheimring circuit. Motorcycle racing career Herz was born in Lampertheim, Grand Duchy of Hesse. He started his career in 1932 with DKW and went over to NSU in 1939.
