Name the surfaces
Choose Aerodynamic system to fade the mechanical parts. The front wing, floor, diffuser and rear wing remain; they are the surfaces used in this schematic discussion.
Double the speed
Set air speed to 40 m/s, then 80 m/s. The downforce index rises from 25 to 100: doubling speed makes this fixed-coefficient model’s index four times larger.
Read the split
The front and rear blue arrow lengths use a fixed 45% / 55% split. Doubling speed quadruples both lengths; at zero speed neither load arrow appears. The split makes two locations visible; it is not an aerodynamic balance prediction.
Keep the boundary
The car is generic. The scene uses q proportional to V², with density, area and aerodynamic coefficient fixed. It does not calculate a flow field, pressure, drag, tire load or lap time.
The main parts
- Front wing
- A multi-element schematic wing ahead of the front wheels. It is isolated as an aerodynamic surface, not a regulated profile.
- Floor and fences
- The flat underbody and its fences represent a controlled flow path beneath the car. This model does not calculate pressure beneath it.
- Rear diffuser
- The rising rear-floor region is shown as a distinct geometry. It is not a CFD result and no diffuser performance is claimed.
- Rear wing
- A high rear aerodynamic surface. Its blue arrow shares the lesson’s fixed illustrative rear proportion.
- Survival cell and cockpit
- The central capsule, nose, sidepods and halo-like hoop are an original teaching silhouette, not a homologated chassis design.
- Suspension links
- Rods connect the body to wheel locations. Their forces, steering, compliance and geometry changes are outside the model.
- Open wheels
- The wheels rotate only to make prescribed air speed legible. Tire grip, braking and wheel-wake effects are not simulated.
- Power-unit volume
- An orange rear volume represents packaged propulsion. It has no engine cycle, output or energy-recovery model.
- Air-speed cues
- Orange marks indicate a prescribed stream direction. Each blue arrow's length is directly proportional to its unitless load index: twice the index gives twice the length, and zero hides the arrow. Their tips stay above the wing surfaces. They are not computed pressures or measured forces.
