SEMINAR ON
F1 TRACK DESIGN AND SAFETY

Introduction
 Most sophisticated vehicles used in the most
technologically advanced form of sports.
 Each and every minute details tuned to perfection
 Each f1 team has the responsibility to come up
with the most efficient design.
 Bringing the f1 cars to a halt is an incredible
challenge.
 F1 car driving demands precision, incredibly fast
reflexes and endurance from the driver.

The Chassis
 Characteristics
• Single seat cars
• Open cockpit
• Open wheels
• Wings at front and rear
• Position of the engine is behind the driver

The Cockpit
 Cockpit is a very sparse environment.
 Driver has limited movement.
 Driver experiences G-forces.
 Designers are forever trying to lower the centre
of gravity of the car.

Aerodynamics
 Wing theory
 Rear wing
 Front wing
 Barge boards
 Diffuser

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.

Rear wing
 Made up of 2 sets of aerofoil connected to each
other by wing endplates.
 Top aerofoil made up of a maximum of 3 elements.
 Lower aerofoil made up of single element.
 Endplates prevent the air from spilling over the
sides of the wings.

Front wing
 Asymmetrical wing flaps on either side of the nose
cones.
 Asymmetrical shape allows better airflow
increasing down-force.
 Inside edges of the front wing endplates curved.

Barge-boards
 Mounted between front wheels and side-pods.
 Can be situated in the suspension.
 Main purpose- Smoothen and direct the airflow
coming from the front wheels.
 They have contours to direct airflow in different
directions.

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.

Engine
 Ten times horse-power of a normal road car.
 Operate at very high temperatures.
 Limited to 3 litre, normally with 10 cylinders.
 Engines made from forged aluminium.
 Some components made from ceramics in order to
reduce internal inertia of moving parts.

What makes these engines
different to road car engines?
 Air-box
 Fuel and fuel tank
 Exhausts
 Cooling systems
 Transmissions
• Clutch
• Gearbox
• Gear ratios
• Differential

Tyres
 Must be able to withstand very high stresses and
temperatures.
 Tyres filled with special nitrogen rich, moisture
free gas.
 Tyres made up of 4 ingredients- carbon blacks,
polymers, oils and curatives.
 3 types of tyres are used
• Dry tyre
• Intermediate tyre
• Wet tyre

The Suspensions
 Two forms of suspension.
• Traditional coil spring setup.
• Torsion bar setup
 Both forms are mounted on the chassis.

Dampers
 Often called shock absorbers.
 Main purpose is to prevent the spring from
oscillating too much
 These dampers can be tuned to alter the
handling.

The Brakes
 F1 cars use disc brakes designed to work at 750
degrees celcius.
 Brakes are set up with 60% braking force to the
front and 40% to the rear.
 Drivers are able to adjust the balance btw front
and rear braking force from a dial in the cockpit.
 Rotating discs are gripped by caliper squeezing
the disc.
 Discs are drilled for airflow to keep temperature
down.
 Front and rear braking systems are connected
separately

Steering wheel and pedals
 A sophisticated steering wheel with all the
information available.
 On the front of the wheel items such as rev
lights, speed limit button, fuel mixture controls,
radio buttons etc. are provided.
 Levers for changing gears are located on the
back of the wheel.
 Pedals are designed specifically for each driver.
 Only 2 pedals are available- for acceleration and
for braking.

1. Regulates front brakes
2 .Regulates rear brakes
3 .Rev Shift lights
4 – 5. Lap time display
6 .Neutral gear buttons
7. Display for Gear, engine RPM, water &
oil temperatures
8 .Engine cut-off switch
9 .Place to add small map of track with
sector breakdowns
10. Activates drink bottle pump
11 .Brake balance selector
12 .Manual activation of fuel door
13 .Air / fuel mix selector
14 .Power steering servo regulator
15 .Specific car program recall
16 .Engine mapping selector
17 .Selection 'enter' key
18 .Electronic throttle regulators
19 .Change menus on display
20 .Pits to car radio activation
21 .Pit lane speed limiter activation


 GRAND TOTAL € 926,490
In addition to the build costs, thousands of pounds will be spent
on designing the car. Design costs include the making of models,
using the wind tunnel and paying crash test expenses etc. The
cost of producing the final product will be €7,700,000

Random facts about f1
 In an f1 engine revving at 18000rpm, piston travels
up and down 300 times a second.
 If a connecting rod let go of its piston at max speed,
the piston would have enough energy to travel
vertically over 100 metres.
 If a water hose were to blow off, complete cooling
system would empty in just over a second.
 F1 cars have 3 built in pneumatic jacks.
 F1 car has as many as 8 radios operating at a time.

Conclusion
 The car’s engine, suspension, aerodynamics, tyres etc
determine how fast they go.
 The engineering of materials, cooling system,
aerodynamics and high temperature structural
stiffness of f1 components is leading edge
technology.
 Getting the car tuned up and keeping it in a state of
perfection are 2 of the team’s most important tasks
during a season.
