Aerodynamics Module

AerodynamicsModule inspector.

Calculates and applies aerodynamic drag and downforce.

Drag
  • Drag depends on vehicle dimensions. Those can be adjusted under vehicle's Settings tab.
  • Drag is calculated bot in longitudinal and lateral directions. Intensity of drag can be adjusted through Frontal Cd and Side Cd (Cd = coefficient of drag) fields. Data for different vehicles is available here.
Downforce

Downforce is calculated in a simplified fashion by applying downforce to a number of points over the vehicle. In the simplest form a single downforce point at the center of the vehicle can be used, or one point at the front and one point at the end of the vehicle.

  • Vertical position of Downforce Points should be below the WheelController position, or even as low as the floor of the vehicle. This is because all the force is applied in a single point which, if applied too high, can cause the vehicle to snap oversteer when changing direction.
  • Downforce is not dependent on vehicle shape or dimensions. It is calculated through Downforce Points and Max Downforce Speed.
  • Downforce increases exponentially from 0 to Max Downforce Speed at which it reaches Max Force value.
  • Enable Gizmos to be able to see downforce points (red sphere).
