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 metres) track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, and aerodynamics.
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.
Two Top Fuel dragsters side by side during an NHRA event in 2012. Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 338.94 miles per hour (545.5 km/h) and finishing the 1,000 foot (304.8 m) runs in 3.641 seconds.
Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) 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.
Wynns Stormer is a streamliner dragster. [1]Built in 1972 by Woody Gilmore (who also produced Don Prudhomme's wedge digger), on a Woody chassis, [2] the car had bicycle front wheels and dropped front axle, a very pointed nose, and an engine cover with broad, wedge-like fairings over the exhaust pipes, ahead of the rear tires; the fairings sloped steeply from track level to the top of the tires.
In theory, the wedge body offered an aerodynamic advantage, decreasing turbulent airflow over the rear wheels, as well as increasing downforce; [3] in practise, the extra weight exceeded any advantage. Miller ran the car for the 1974 season, but had "mixed results"; [1] the car had no obvious edge over more conventional rear-engined dragsters.
Educating themselves on the mechanics of aerodynamics is helpful. It’s called intellectualizing as a defense mechanism. CNN: Some people may think, “Although plane accidents are rare, I never ...
