The front wheels of an open-wheeled F1 car generate aerodynamic drag. The thinking behind the Tyrrell P34 was that this drag effect could be reduced by using smaller diameter tyres at the front. At the time, conventional F1 front wheels would measure around 16" (40 cm) diameter but Tyrrell planned to use just 10" (25 cm) diameter wheels.
In motor racing, the drag reduction system (DRS) is a form of driver-adjustable bodywork aimed at reducing aerodynamic drag in order to increase top speed and promote overtaking. It is an adjustable rear wing of the car, which moves in response to driver commands. [ 1 ]
His 1961 car attempted to use the shaped underside method but there were too many other aerodynamic problems with the car for it to work properly. His 1966 cars used a dramatic high wing for their downforce. His Chaparral 2J "sucker car" of 1970 was revolutionary. It had two fans at the rear of the car driven by a dedicated two-stroke engine ...
As the speed of cars increased during the 1920s and 1930s, designers observed and began to apply the principles of automotive aerodynamics. [2] As aerodynamic drag increases, more energy, and thus more fuel, is required to propel the vehicle. [3] In 1922, Paul Jaray patented a car based on a teardrop profile (i.e. with a rounded nose and long ...
The term drag area derives from aerodynamics, where it is the product of some reference area (such as cross-sectional area, total surface area, or similar) and the drag coefficient. In 2003, Car and Driver magazine adopted this metric as a more intuitive way to compare the aerodynamic efficiency of various automobiles.
As a result of the T.50’s fan-assisted aerodynamic design, the need for any aerodynamic package on the front or rear of the T.50, such as a splitter, a wing or an aggressive aerodynamic design are considered ineffective in providing further downforce and are thus considered negligible, allowing a free form and flowing exterior design. The T ...
The low-pressure wake behind a group's leading car reduces the aerodynamic resistance on the front of the trailing car, allowing the second car to pull closer. As the second car nears the first, it pushes high-pressure air forward so less fast-moving air hits the lead car's spoiler. The result is less drag for both cars, allowing faster speeds. [3]
The North American P-51 Mustang makes significant use of the Meredith effect in its belly radiator design. [1]The Meredith effect is a phenomenon whereby the aerodynamic drag produced by a cooling radiator may be offset by careful design of the cooling duct such that useful thrust is produced by the expansion of the hot air in the duct.
