3. Highest class of auto racing
sanctioned by the Federation
Internationale de I’Automobile
(FIA)
Formula one cars race at high
speeds up to 360 km per hour
with engines reviving up to a
formula imposed limit of 18,000
rpm
Performance of the cars is highly
dependent on Aerodynamics,
Suspension, Electronics and Tyres
Teams spend tens of millions of
dollars on research and develop-
ment in the field of aerodynamics
each year
4. EARLY DEVELOPMENTS
No knowledge of aerodynamics
Engine Power was important in
producing faster lap times
Use of soft rubber compounds
and wider tyres demonstrates
the importance of good adhesion
and cornering ability
6. Concept: Inverted Wing
• Fixed Angle of Attack of the wing
• Mechanism for controlling the
incidence angle
• Mounted the wing directly on
the unsprung wheel assembly
• Very High mounted wings
7. Formula 1 Teams: Vision
Creation of Downforce
Push the car's tyres onto the track and improve cornering
forces
Minimising the drag
Caused by turbulence and acts to slow the car down
9. Ground Effect Aerodynamics
(Introduction of Skirts)
Ground effects was another innovation brought to F1 by Colin
Chapman's Lotus team
Idea: Making the entire car function as one giant wing to increase
downforce
11. Diffuser
Sculptured under-body tunnels were
prohibited
Idea: Sculpting the underbody of a
car into 2 tunnels and the effect is
similar to a venturi effect
Aim: To decelerate the air
without it separating from the
tunnel walls
Installing an inverted wing close
to the diffuser exit is possible to
produce higher downforce
12. REAR WING
Comprised of two set of airfoils
connected to each other by the wing
end-plates
Use of endplates to prevent air
spillage around the wing tips
Splitting the aerofoil into
separate elements as seen in is
one way to overcome the flow
separation
Rear Wing varies from track
to track
13. Smoothening the flow and
reducing the drag
Bargeboards first seen in 1993
Smoothen the airflow around the
car and into the radiator intakes
To overcome the problem of
unnecessary turbulence in front
of the wheels
Many teams sculpted outside
edges to the endplates to direct
the air around the front wheels
16. Improving The Show
Drag reduction System (DRS)
aimed at reducing aerodynamic
drag in order to promote
overtaking
Adjustable flap on the the
rear wing of the car which
opens and closes in
correspondence with a driver’s
commands
Conditions for using DRS:
Pursuing car within a
second and in activation
zone
Once two racing laps
