A Seminar Presentation On
AERODYNAMICS OF SPORTS CAR
SUBMITED BY-NAVEEN KUMAR VERMA
In the Era of 1900-1950,There
is no scope of aerodynamics.
Shape of the vehicle is not
Speed of the car is improved
but the design of the
aerodynamics is not improved.
• Automotive aerodynamics is the study of
the aerodynamics of road vehicles. Its main
goals are reducing drag and wind noise,
minimizing noise emission, and preventing
undesired lift forces and other causes of
aerodynamic instability at high speeds.
WHAT IS AERODYNAMICS ?
• Aerodynamics is the branch of dynamics that
deals with the motion of air and other gaseous fluids
and with the forces acting on bodies in motion
relative to such fluids.
• In the term AERODYNAMIS, AERO stands for
air, DYNAMICS denotes motion. Aerodynamics is
an engineering science concerned with interaction
between bodies and atmosphere.
NEED OF AERODYNAMICS
better the aerodynamic design,
higher will be their speeds.
better aerodynamics , less
work for engine.
FORCES ACTING ON SPORTS CAR
Trends in maximumcornering force,during the past 50 years
Uses the same principle as an aircraft.
Aircraft uses lift whereas SPORTS cars uses down-
Drag- another important factor on SPORTS car.
It is a device whose intended design is to generate down force as air
passes around it, not simply disrupt existing airflow patterns
A spoiler is an automotive aerodynamic device whose intended design
function is to 'spoil' unfavorable air movement across a body of a vehicle
in motion, usually described as turbulence or drag.
Spoilers on the front of a vehicle are often called air dams
• AIRDAM is the front area of sport car.
Spoilers on the front of a vehicle are often called air
dams, because in addition to directing air flow they also
reduce the amount of air flowing underneath
the vehicle which generally reduces aerodynamic lift
FRONT END OF SPORTS CAR
Situated at the underside of the car behind the rear axle line.
Consists of many tunnels and splitters to control airflow.
Maximizes suction effect thus increasing down-force
Weight of the
• Aerodynamics is now the most important item on the
car which a team can actually change, because if you
look at the tires, everyone has the same tires and the
engine is homologated. So aerodynamics is the single
biggest item we can change - the biggest performance
item on the car.
• Although they may seem restricted by tight regulations,
these regulations only add more challenge to the game
that engineers must play.
