Three Things You Can Do to Reduce Drag in CO2 Cars
- Golf Balling. Covering the surface of your car with small, semi-circular pits ("golf balling") does two things. ...
- Get Low. The bottom of your car experiences just as much drag as the top, so make sure to keep things smooth and straight all the way around. ...
- Sleek Over Small.

What causes the reaction when racing your CO2 car?
CO2 cars are propelled by carbon dioxide rapidly escaping from the cartridge. ... The reaction part of Newton's law is fulfilled by the car's movement. Remember that the reaction occurs in the opposite direction: when gas escapes rearward, the car moves forward. As the car begins to move, its inertia is overcome.
What powers does CO2 dragster have?
Your dragster uses a CO2 cartridge for power. The cartridge contains CO2 gas under pressure. The end is punctured so the gas escapes creating thrust or force that powers your dragster down the track.
What keeps the dragsters from flying off the track?
Two hooks (eyelets or screw eyes) linked to a string (usually monofilament fishing line) on the bottom of the car prevent the vehicle from losing control during launch.
How fast does a dragster go?
Among the fastest-accelerating machines in the world, 11,000-horsepower Top Fuel dragsters are often referred to as the “kings of the sport,” and with good reason. They are capable of covering the dragstrip in less than 3.7 seconds at more than 330 mph.
How fast does a CO2 dragster go?
In this type of racing, the participant builds a small carbon dioxide cartridge into the car, which propels it down a flat, level track. They're fast, too -- on a 65.5-foot (20-meter) track, the cars can cross the finish line in just over a second, traveling at nearly 70 miles per hour (112.7 kilometers per hour)!
What is the best shape for a dragster?
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 happens when you puncture a CO2 canister?
You will have to re-inflate your tyre with normal air, which includes larger molecule that leak out slower. If you don't use all the CO2 gas in the cartridge, it will leak out over the next ~30 minutes approximately.
What causes a CO2 dragster to decelerate?
Effects of Forces on the Dragster
The thrust force of the CO2 cartridge accelerates the vehicle. The air resistance (or drag force) works against the thrust force and causes the car to decelerate.
How do you reduce drag on a car?
Methods of decreasing the drag coefficient of a vehicle include re-shaping the rear end, covering the underside of the vehicles, and reducing the amount of protrusions on the surface of the car.
How useful are spoilers?
Spoilers are supposed to change airflow above, around and underneath vehicles to reduce wind resistance (or drag) or use the air to create more downforce and enable more grip at high speeds. They're designed to “spoil” the airflow to reduce its negative effects.
What does the C and O stand for in CO2?
CO2 is the chemical formula for the compound carbon dioxide. C is the symbol for the element carbon, and O is the symbol for oxygen.
How are CO2 dragsters propelled?
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.
What is the fastest CO2 car in the world?
On the 15th October 1997, at Black Rock, Nevada USA, Andy Green piloted the Trust SSC (SuperSonic Car) and achieved what was previously thought impossible. He travelled at a speed of 1,227.985 km/h (Mach 1.020) and broke the sound barrier.
How are CO2 cars launched?
Once the cars are ready to race, the sealed CO2 cartridge is inserted and they are placed on the starting grid. They're hooked up to a device called a launch pod, which punctures the cartridges of the two cars at the same time.
