3. What is formula one
• Highest class of auto racing sanctioned by the federation
international de l’Automobile (FIA)
• “ the pinnacle of motor sports”
• high speeds up to 400km per hour
• engines reviving up to a formula imposed limit of 20,000 rpm
• There are 22 grand prix and 10 teams
• They race In some iconic circuits , such as Silverstone, red bull
ring, Suzuka circuit etc
5. Rules and regulations
• Bodywork
• dimensions
• Sti
ff
ness
• Engines
• Impact and roll structure testing
• Suspension
• Steering system
• Weight
• Refuelling
• Scoring
• Penalties
• Safety
• No of times parts can be changed
7. Performance of the car
• Aerodynamics of the car
• Engines
• engine electronics
• Mechanical parts
• Tyres
• Cooling requirements
• Suspensions
• More importantly man behind the steering
9. Aerodynamics of f1 car
• The principle that allows an aeroplane to rise o the ground by
creating lift is used in reverse to apply force that presses the car
against the surface. This e
ff
ect is called aerodynamic grip
• Increase downforce of the car
• Reduce the drag on the car and consequently improving top
speed
• Both are interrelated to each other
• Downforce describes the downward pressure created by the
aerodynamics of the car
10. How the downforce is generated
• Downforce describes the downward pressure created by the
aerodynamic characteristic of the car
• It can only be achieved at the cost of increased drag
• In f1 it occurs due to two things that are present in the car 1st
one is the front wing and second one is the rear wing
11. Rear diffuser
• Gather and organise the high speed air rushing under the car
• preventing
fl
ow separation from the under tray pro le
• de
fi
ned for reducing drag losses
• major important factor is to achieve the higher velocity (low
pressure)
12. Tyres
• The only point of contact with track surface
• Acceleration and corning very much depends on the tyres interaction
• There are 5 types of tyre: c1, c2, c3, c4, c5
• 1st three are dry tyres which are di
ff
erent from each other by hardness,
grip, long-lasting, versatile, material
• Last 2 are rain tyres
• c5 tyre can disperse almost 85 lit/sec of water from the track
(technically it acts as a boat in heavy rain fall)
13. Engine
• it’s called a ‘power unit’ – it’s a hybrid. It consists of a petrol
internal combustion engine and electric motors powered by an
Energy Recovery System. (ERS).
• The engine is a four-stroke 1.6-litre turbo V6.
• the cylinders arranged in a 90-degree ‘V’ con guration and two
inlet and exhaust valves per cylinder
• The total power output from the combined petrol and electric
elements is around 1,000bhp. The petrol engine runs at
15,000rpm
• At this moment red bull has the best engine ever
14. Steering wheel
• Most important interface for driver
• Controls for engines mixtures, engine map, car-pit radio etc are
set in the steering
• The steering wheel only cost around $200000 (1crore 60 lakh
INR )
• All the controls are set according to the driver
• Through this driver can interact with the car, the crew members
and can access to all the sensor reports
16. Barge board
• directing di
ff
erent parts of the
Air that is entering towards the car
• protects the car from the dirty air that
Is entering towards the body of the car
• direct the votex that is generated
By the front wing
• generate its own vortex near the ground level
To seal the air
fl
owing under the car
17. s-duct system
•It solves two problems
•1st one is it solves the boundary layer problems under the car
•the next one is the air that escapes above the body due to the shape of
the nose it keeps the air close to the surface and make it ow smoothly
18. D R S
• Drag reduction system
• When the car goes straight it does not need much downforce
so if the downforce is reduced then the car can go faster due to
decrease in drag
• We can do so by straightening the top ap of the rear wing
which will make the air go straight by using a ap controlling
system at the centre of the wing
19. The MGUs
• This is called motor generator units
• convert mechanical and heat energy to electrical energy
• two types, one is motor generator unit-heat (mgu-h) and motor
generator unit-kinetic (mgu-k)
• The mgu-k is in use while braking and the mgu-h uses the heat
energy from the exhaust gases to produce electricity
20. Some interesting facts
• It has more then 500 type of rules and regulations which is more
then any other races
• The G-force (5-6 G) and heat (50 C) in the cockpit is so high that it
can reduce 4kg of drivers weight.
• No car can match its turn taking speed
• Racing tyres lose around 0.5kg of material during a race
• Some of the best f1 pit crews can change the tires in just three
seconds.
• The engine con fi
guration is same so the teams has to make
engine more ef
fi
cient then other
• This race is so big that companies those who participate in the
race states that the performance shown by their company in the
race is how the company really is
