Aerodynamic Properties of Shapes

Wedge - A good aerodynamic shape because of it’s long gradual slope. Which allows the air to travel over the surface easily. Rectangle - A very bad aerodynamic shape because of it’s high flat side. Which blocks the air from traveling around the surface.

Aerodynamic Properties of Shapes

Sphere - A very good aerodynamic shape because of it symmetrical shape. Which allows air to flow over it’s surface with very little disruption to the air stream.

Weight Distribution

This equation has to do with how much weight is over the front and rear of the vehicle.

Forces That act upon a Co2 cars

  • Lift - an upward force resulting from air

being forced underneath a car.

  • Drag - air resistance that pushes against a

vehicle.

  • Thrust - a forward force produced by an

engine or turbine.

  • Gravity - force acting on a car trying to

hold it down to the earth.

Weight to thrust ratio

  • When a car is too heavy, it is hard to get

into motion but once in motion it stays in motion easily.

  • When a car is very light, it is easy to get

into motion, but it requires constant thrust to stay in motion.

  • Finding a middle ground is key. Can’t be

too heavy or too light.
