Aerodynamics CO2 Dragster. Aerodynamics:. Is the study of Air Flow around a moving vehicle. Good Aerodynamics offer the least resistance. Aerodynamics address four main areas of concern. (Frontal Pressure, Lift/Down Force and Drag.) . Drag. Enemy of race cars.
Enemy of race cars.
Drag, is comprised primarily of two forces, Frontal Pressure and Lift / Down Force.
These forces if not taken care of by good aerodynamic features can ruin a cars performance.
Frontal Pressure is caused by the air attempting to flow around the front of the car.
Rear Vacuum is caused by the "hole" left in the air as the car passes through it.
Down force is the same as the lift experienced by airplane wings, only it acts to press down, instead of lifting up.
Not to be forgotten, the underside of the car is also responsible for creating a good amount of down force.
