What is the best design for a CO2 dragster?

What is the best design 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.

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 do you make a CO2 dragster?

1. Step 1: Create Design. To create my design, I used CorelDraw x3.
2. Step 2: Print Design and Cut. I then laser printed my design on the wood, I used a saw to cut it out.
3. Step 3: Drill Holes.
4. Step 4: Add Axels.
5. Step 5: Use Washers.
6. Step 6: Add Wheels.
7. Step 7: Add CO2 Cartridge, and GO!
8. Step 8: Ask Questions!

How does a CO2 dragster car work?

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 happens when you puncture a c02 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.

Why are dragsters shaped the way they are?

The driver sits angled backward, over the top of the differential in a cockpit situated between the two rear tires, a design originating with Mickey Thompson’s Panorama City Special in 1954, as a way of improving traction. This position led to many drivers being maimed when catastrophic clutch failures occurred.

How fast can a CO2 dragster 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.

How do you determine the speed of the CO2 dragster?

Using a Pitsco launch and timing system, test the dragster using an 8-gram CO2 cartridge and time it for a 20-meter distance. The average velocity is calculated using the formula velocity equals distance (meters) divided by time (seconds), or v = d/t.

What are CO2 dragsters made of?

CO2 dragsters are made of lightweight material usually balsawood or basswood. They are propelled down a track by compressed carbon dioxide gas. The CO2 cartridge is punctured so the compressed gas can rapidly leave the canister causing the dragster to move.

How fast do CO2 dragsters 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)!
