Title: F1 CARS


1
F1 CARS
2
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.

3
The Chassis
  • Characteristics
  • Single seat cars
  • Open cockpit
  • Open wheels
  • Wings at front and rear
  • Position of the engine is behind the driver

4
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.

5
Aerodynamics
  • Wing theory
  • Rear wing
  • Front wing
  • Barge boards
  • Diffuser

6
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.

7
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.

8
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.

9
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.

10
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.

11
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.

12
What makes these engines different to road car
engines?
  • Air-box
  • Fuel and fuel tank
  • Exhausts
  • Cooling systems
  • Transmissions
  • Clutch
  • Gearbox
  • Gear ratios
  • Differential

13
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

15
The Suspensions
  • Two forms of suspension.
  • Traditional coil spring setup.
  • Torsion bar setup
  • Both forms are mounted on the chassis.

16
  • 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.

17
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

18
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.

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
21
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.

22
Conclusion
  • The cars 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 teams most
    important tasks during a season.
