Frontal Area
The drag coefficient is a common measure in automotive design as it pertains to aerodynamics. Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics. Aerodynamic drag increases with the square of speed; therefore it becomes critically important at higher speeds. Reducing the drag coefficient in an automobile improves the performance of the vehicle as it pertains to speed and fuel efficiency. There are many different ways to reduce the drag of a vehicle. A common way to measure the drag of the vehicle is through the drag area. The importance of drag reduction The reduction of drag in road vehicles has led to increases in the top speed of the vehicle and the vehicle's fuel efficiency, as well ...

Rumpler Tropfenwagen
The Rumpler Tropfenwagen ("Rumpler drop car", named after its raindrop shape) was a car developed by Austrian engineer Edmund Rumpler. The Tropfenwagen Aerodynamics Rumpler, born in Vienna, was known as a designer of aircraft when at the 1921 Berlin car show he introduced the Tropfenwagen. It was to be the first ''streamlined'' production car, before the Chrysler Airflow and Tatra T77. The Rumpler was already wind tunnel optimized at the Aerodynamics Research Institute in Göttingen and had a Automobile drag coefficient, drag coefficient of only 0.28, a value that astonished later engineers when they tested the Tropfenwagen in the 1970s. This would be competitive even today. For comparison: the top ten most aerodynamic production cars in 2014/2015 were in the range 0.26 down to 0.19. The Fiat 508, Fiat ''Balilla'' of the mid-1930s, by contrast, was rated at 0.60. To enable the car's aerodynamic shape, the Tropfenwagen also featured the world's first (single plane) curved windows in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Motors Precept
A precept (from the , to teach) is a commandment, instruction, or order intended as an authoritative rule of action. Religious law In religion, precepts are usually commands respecting moral conduct. Christianity The term is encountered frequently in the Jewish and Christian Scriptures: The usage of precepts in the Revised Standard Version of the Bible corresponds with that of the Hebrew Bible. The Septuagint (Samuel Rengster edition) has Greek ''entolas'', which, too, may be rendered with precepts. Latin Catholicism The Latin Church of the Catholic Church's canon law, which is based on Roman Law, makes a distinction between ''precept'' and ''law'' in Canon 49: In Catholicism, the " Commandments of the Church" may also be called "Precepts of the Church". Buddhism In Buddhism, the fundamental code of ethics is known as the Five Precepts (''Pañcaśīla'' in Sanskrit, or ''Pañcasīla'' in Pāli), practiced by laypeople, either for a given period of time or for a ...

Alfa Romeo BAT
The Alfa Romeo BAT (or Berlina Aerodinamica Tecnica) are a series of Italian concept cars. The cars originated from a joint collaboration project between Alfa Romeo and the Italian design house Gruppo Bertone, Bertone that began in 1953. Three cars were built: the BAT 5 in 1953, the BAT 7 in 1954, and finally the BAT 9 in 1955. All three cars were designed by Franco Scaglione. History Alfa Romeo contacted Nuccio Bertone of the Bertone design house and commissioned three concept vehicles to research the effects of drag on a vehicle. The idea was to create vehicles with the lowest possible drag coefficient. They were built upon the Alfa Romeo 1900 chassis. Each of the three cars was presented at the Turin Auto Show, in 1953, 1954 and 1955 respectively. The lowest of the three cars' drag coefficient was 0.19, an achievement even by today's standards. For each of the cars, Alfa Romeo provided a five-speed gearbox and a powerful four-cylinder engine that produced more than , good eno ...

Dymaxion Car
The Dymaxion car was designed by American inventor Buckminster Fuller during the Great Depression and featured prominently at Chicago's 1933/1934 World's Fair. Fuller built three experimental prototypes with naval architect Starling Burgess – using donated money as well as a family inheritance – to explore not an automobile per se, but the 'ground-taxiing phase' of a vehicle that might one day be designed to fly, land and drive – an "Omni-Medium Transport". Fuller associated the word ''Dymaxion'' with much of his work, a portmanteau of the words ''dynamic'', ''maximum'', and ''tension'', to summarize his goal to do more with less. The Dymaxion's aerodynamic bodywork was designed for increased fuel efficiency and top speed, and its platform featured a lightweight hinged chassis, rear-mounted V8 engine, front-wheel drive (a rare ''RF'' layout), and three wheels. With steering via its third wheel at the rear (capable of 90° steering lock), the vehicle co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
