Rear view of a "rail"-style dragster, with external wheels. The hollow container for the carbon dioxide cartridge can be seen towards the rear of the car. CO 2 dragsters are cars used as miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a typically 60 feet (18 ...
Initial tests with the short-tail version of the car resulted in an average speed of 250.919 mph (403.815 km/h), falling just short of the closed-course speed record set by the Mercedes CIII-IV development prototype. As the team adjusted the car's aerodynamics, Foyt tested the second, long-tail car.
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.
Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. Air is also considered a fluid in this case.
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.
Designed by dragster and funny car builder Sammy Miller in 1974, the car was allegedly a product of Miller's dislike of repeated funny car fires. It featured bicycle front wheels, a low-mounted, front-sloping rear wing, and a mid-mounted engine (placed further ahead of the rear axle than most similar dragsters). [ 1 ]
Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline 's average energy expenditure ...
DARPA's Falcon Hypersonic Technology Vehicle-2 is arrowhead-shaped. Development of protection structures that are tough and lightweight; an aerodynamic shape that has a high lift to drag ratio; automatic navigation control systems were among the initial technical challenges facing the designers. [6]
