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 ver ...

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 orbits of planets in the once popular geocentric Ptolemaic system are epitrochoids (see deferent and epicycle). The orbit of the moon, when centered around the sun, approximates an epitrochoid. The combustion chamber of the Wankel engine is an epitroch ...

Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an Eccentric (mechanism), eccentric rotary combustion engine, rotary design to convert pressure into rotating motion. It was invented by German engineer Felix Wankel, and designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor, which creates the turning motion, is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor rotates inside an oval-like epitrochoidal housing, around a central output shaft. The rotor spins in a hula-hoop fashion around the central output shaft, spinning the shaft via toothed gearing. Due to its inherent poor thermodynamics, the Wankel engine has a significantly worse thermal efficiency and worse exhaust gas behaviour when compared against the Otto engine or the Diesel engine, which is why the Wankel engine has seen limited use since its introduction in the 1960s. However, its advantages of compact design, smoothness, lower weight and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Drag Coefficient
In fluid dynamics, the drag coefficient (commonly denoted as: c_\mathrm, c_x or c_) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area. The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. The drag coefficient of a complete structure such as an aircraft also includes the effects of interference drag. Definition The drag coefficient c_\mathrm d is defined as c_\mathrm d = \dfrac where: * F_\mathrm d is the drag force, which is by definition the force component in the direction of the flow velocity; * ...

Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

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 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 straightaway for speed tr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 and technology, with about 28,000 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 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 Isar barracks were built on the island and, after the flooding of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
