Porsche 909
The Porsche 909 "Bergspyder" was a spyder sports car designed and built by Porsche in 1968. Its purpose was to compete in hillclimbing competitions, specifically the EHCC Sports Car (Gr. P) class of the European Hillclimb Championship. It was a short-lived model, but its basic structure, technical innovations, and overall design became the basis for the successful 908/3. History Porsche had reigned champion with earlier models, the 910, 907, and 908, winning nine European Hillclimb Championship titles out of eleven years of participation. After being defeated two years in a row, Ferrari set out to develop a dedicated hillclimb car to challenge Porsche in 1967. This car was the 212 E Montagna, and was announced to compete for the 1968 European Hillclimb Championship. Despite this initial claim, Ferrari postponed its development, with the car being unveiled in 1969. Still, given the shocking news at the time of the 212's announcement, Ferdinand Piëch and his team of engineer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche Flat-eight Engines
German carmaker Porsche built several series of flat-eight engines of differing displacements over the course of many years. They were mainly used in Porsche's racing cars. Type 753 The first Porsche flat-eight was the Type 753. Work began on it in 1960, following the announcement of a 1.5-litre displacement limit for the 1961 Formula One (F1) season. The design of the new F1 engine was done by Hans Hönick and Hans Mezger. The 753 inherited the traditional Porsche features of a boxer layout and air-cooling, but with the number of cylinders increased to eight. Bore and stroke were respectively, resulting in a displacement of . The oversquare dimensions kept piston speeds low, and also kept the engine narrow and as far out of the airflow on the sides of the car's tub as possible, although it was still wider than the 120° V6 and 90° V8s of the competition. The centre of the engine was a magnesium crankcase cast in two halves split vertically along the centre-line of the cranksha ...

Sports Prototypes
A sports prototype, sometimes referred to simply as a prototype, is a type of race car that is used in high-level categories of sports car racing. They are purpose-built auto-sports race cars, as opposed to production-car based or street-legal, low-volume homologation specials – thus entirely not intended for consumer purchase, or production beyond the fabrication of the (nearly) unique cars entered into races and in race-car competition classes or "formulas", with sufficiently open regulations to allow for vehicles of unique design to partake. Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: ''grand tourers (GT cars)'', which are strictly based on production street cars, and ''sports prototypes'', which are allowed a great amount of flexibility within set ru ...

Magnesium
Magnesium is a chemical element; it has Symbol (chemistry), symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table), it occurs naturally only in combination with other elements and almost always has an oxidation state of +2. It reacts readily with air to form a thin Passivation (chemistry), passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium Salt (chemistry), salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight magnesium alloy, alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three Helium nucleus, helium nuclei to a carbon nucleus. When such stars explo ...

Silver
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanium
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide (TiO2), is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and cata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beryllium
Beryllium is a chemical element; it has Symbol (chemistry), symbol Be and atomic number 4. It is a steel-gray, hard, strong, lightweight and brittle alkaline earth metal. It is a divalent element that occurs naturally only in combination with other elements to form minerals. Gemstones high in beryllium include beryl (Aquamarine (gemstone), aquamarine, emerald, red beryl) and chrysoberyl. It is a Abundance of the chemical elements#Universe, relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars, beryllium is depleted as it is fused into heavier elements. Beryllium constitutes about 0.0004 percent by mass of Earth's crust. The world's annual beryllium production of 220 tons is usually manufactured by extraction from the mineral beryl, a difficult process because beryllium bonds strongly to oxygen. In structural applications, the combination of high flexural ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spaceframe
In architecture and structural engineering, a space frame or space structure ( 3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut. Chief applications include buildings and vehicles. History Alexander Graham Bell from 1898 to 1908 developed space frames based on tetrahedral geometry. Bell's interest was primarily in using them to make rigid frames for nautical and aeronautical engineering, with the tetrahedral truss being one of his inventions. Max Mengeringhausen developed the space grid system called MERO (acronym of ''MEngeringhausen ROhrbauweise'') in 1943 in Germany, thus initiating the use of space trusses in architecture.
