AERODYNAMICS OF F1 RACING CAR
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.
WHY WE NEED TO IMPROVE AERODYNAMICS IN F1 CARS SPEED
better the aerodynamic design, higher will be their speeds.
FUEL EFFICIENCY
better aerodynamics , less work for engine.
Down force:
It is the negative lift
A high-pressure region then develops on the upper side of the wing, creating a downward force. This pressure difference causes the net down force.
Down force is necessary for maintaining speed through corners. Due to the fact that the engine power available today can overcome much of the opposing forces induced by drag, design attention has been focused on first perfecting the down force properties of a car then addressing drag.
Wing theory
Uses the same principle as an aircraft.
Aircraft uses lift whereas f1 cars uses down-force.
Drag- another important factor on an f1 car.
Working Principle
The basic principle behind this is the Bernoulli’s Principle.
This principle can be used to calculate the lift force on the air foil, if the behavior of the fluid flow in the vicinity of foil is known.
According to this principle, the pressure on the surfaces of the wings will be lower above than below. This pressure difference results in upper lift force, thus lift force can be calculated using this principle .
Rear wing
Diffuser
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
CFD Analysis F1 Car
Technical Regulations Affecting Aerodynamic Features In F1
Weight of the car
Overall width
Overall height
Front bodywork height
CONCLUSION
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.
