A brief engineering explanation for car aerodynamic features and its function. Starting from frontal splitter ending with diffuser and spoiler.

3. AERODYNAMICS DEVICES

4. SPLITTER AND AIR-DAM
• A leading edge on the front of the car,
relatively parallel to the ground
• The air traveling above the splitter will
hit a vertical surface and become
turbulent. This turbulent air is moving
slow, creating a high pressure area.
• How high should the splitter be off the ground?
• How long should the splitter be?

5. DIVE PLATES (Canards)
• These fixtures are typically located on the
right and left sides of the front bumper , and
are curved to redirect airflow at the front of
the vehicle upward.
• Produce downforce
• They’re also used to alter the airflow
along the sides of the vehicle

6. NASA DUCTS (scoops)
• These air scoops are designed to
have minimal impact on airflow,
while still creating an inlet for
airflow

7. SIDE SKIRT
• Side skirts are somewhat similar in principle
to splitters.
• in order to prevent high pressure air from
moving underneath the vehicle.

8. DIFFUSER
• A diffuser is a portion of the underbody
which is shaped to create a location of
increasingly larger air volume below the rear
of the car.
• The diffuser helps to accelerate the air
underneath the car which reduces its
pressure.
• It can also help redirect the airflow
upward, further improving downforce.

9. SPOILER
• spoilers on cars are used to prevent
lift by placing an obstruction in the
path of lift-creating airflow.

10. WING
• they are designed to directly
deflect airflow upwards, pushing
down on the vehicle.
• Airflow interacting with the wing
is forced up, so the vehicle is
forced down.
