Downforce describes the downward pressure created by the aerodynamic characteristics of a car that allows it to travel faster through a corner by holding the car to the track or road surface. Some elements to increase vehicle downforce will also increase drag.
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.
Lowering the drag coefficient comes from streamlining the exterior body of the vehicle. Streamlining the body requires assumptions about the surrounding airspeed and characteristic use of the vehicle. Cars that try to reduce drag employ devices such as spoilers, wings, diffusers, and fins to reduce drag and increase speed in one direction. [4]
The result is less drag for both cars, allowing faster speeds. [3] Handling in corners is affected by balance changes caused by the draft: the leading car has normal front downforce but less rear downforce. The trailing car has less front downforce but normal rear downforce.
If the vehicle is a car, the purpose of downforce is to allow the car to travel faster by increasing the vertical force on the tires, thus creating more grip. If the vehicle is a fixed-wing aircraft, the purpose of the downforce on the horizontal stabilizer is to maintain longitudinal stability and allow the pilot to control the aircraft in pitch.
A retractable front spoiler can reduce the scraping of the car on curbs or other road imperfections, while still reducing drag at high speeds. Powered fans, such as in the Chaparral 2J, do the equivalent of spoilers and increase the downforce, hence the traction and handling of the vehicle (See ground effect). Research continues on the use of ...
Hulu has given a piot order to “Downforce” (working title), a comedy pilot written and executive produced by “Silicon Valley” writers Alec Berg and Adam Countee. The official logline for ...
Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air ...
