What is the best shape for a CO2 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 makes a CO2 dragster fast?

Simply put, the less weight your dragster has, the faster it will go. Because the dragster has parts moving against one another, friction is created. You can help reduce it by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body.

How fast can a CO2 car go?

They’re super quick, on a (20-metre) track, the cars can cross the finish line in just over a second, travelling at a top speed of around 90 kilometers per hour. The CO2 dragster may be small, but it’s going to be moving at incredible speeds when you race it.

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 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.

What is the top speed of a dragster?

338.17 mph
The fastest speed on record is 338.17 mph (Top Fuel) at 1,000 feet. A Top Alcohol Dragster can travel as fast as 285 mph in the quarter-mile. However, in drag racing, elapsed time is the determining factor in winning rounds. The quickest Top Fuel pass on record is 3.623 seconds.

What is the fastest CO2 car in the world?

The recent Braden River High graduate built the fastest CO2 dragster in the nation, racing his way to a first-place finish in the Technology Student Association’s national dragster competition and setting a national record of . 925 seconds on a 65-foot track.

How do you puncture a CO2 car cartridge?

Simply hit the hardwood strip in the center with a hammer and the pin will pierce the Co2 canister, releasing the gas and sending your rocket car on its way. Rocket cars need long, smooth flat tracks to run.

What is the fastest CO2 dragster?

.925 seconds
The recent Braden River High graduate built the fastest CO2 dragster in the nation, racing his way to a first-place finish in the Technology Student Association’s national dragster competition and setting a national record of . 925 seconds on a 65-foot track.

What makes a CO2 powered dragster go fast?

Here are some of the principal forces involved: Mass: Obviously, this is how large and heavy the car is. Simply put, the less weight your dragster has, the faster it will go. Thrust: The gas escaping from the CO2 cartridge in the car. We’ll cover this in a bit. Friction: The second most important fact you’ll face. Drag: Here’s where aerodynamics come into play.

What is the history of the CO2 dragster?

Origins. The concept of miniature dragster racing on tracks predates organized miniature pinewood derby races popular among young boys beginning in 1952.

Education. It was not until the early 1970s that the CO2 dragster hobby received recognition for something other than to pass the time.

The Science.

Organized Events.

How does a CO2 dragster work?

How does a CO2 dragster work? cars are propelled by carbon dioxide rapidly escaping from a small container called a cartridge. The cartridge is positioned in the car so that the escaping gas moves in a rearward direction. The rearward force of the escaping gas is the initial action described by Newton.

How does CO2-powered dragsters work?

Dragsters that use CO2 as a propellant move when CO2 is escaping rapidly from the cartridge that is placed in the car. The placement is such that the gas escapes in a rearward fashion. Because Newton’s Third Law of Motion is in practice the car moves forward, overcoming any resistance in the process.
