What makes a CO2 car fast?
Aerodynamics, thrust-to-weight ratio, surface drag, rolling resistance and friction–all play a role in what makes a CO2 car fast or slow.
What does CO2 do for drag cars?
CO2 dragsters are cars used by miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a 20 metre track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, or aerodynamics.
How do c02 dragsters work?
The wood is sawed and fashioned into an aerodynamic shape, painted and decorated, given wheels, axles and small weights and then raced downhill. In this type of racing, the participant builds a small carbon dioxide cartridge into the car, which propels it down a flat, level track.
What are the 3 main forces that act on your CO2 car?
Here are some of the principal forces involved:
- Mass: Obviously, this is how large and heavy the car is.
- Thrust: The gas escaping from the CO2 cartridge in the car.
- Friction: The second most important fact you’ll face.
- Drag: Here’s where aerodynamics come into play.
What is the most aerodynamic shape for a CO2 car?
Sphere
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. A combination of basic shapes will yield the best results. This equation has to do with how much weight is over the front and rear of the vehicle.
What is the best design for a dragster?
The dragster can be designed with a practical, aerodynamic shape, modeled after an actual racecar or given a crazy, eye-catching appearance. Paint, decals and add-ons are common ways to decorate them.
What is a CO2 drag car?
CO2 dragsters are cars used by miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a typically 60 feet (18 metres) track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, or aerodynamics.
What are CO2 powered cars?
CO2 powered cars are model dragsters that are propelled by the thrust from a CO2 cartridge. These cars are routinely used in middle school and high school-level engineering classes as a way for students to learn about the dynamics of car design.
