Step 1: Create Design. To create my design, I used CorelDraw x3. Step 2: Print Design and Cut. I then laser printed my design on the wood, I used a saw to cut it out. Step 3: Drill Holes. Step 4: Add Axels. Step 5: Use Washers. Step 6: Add Wheels. Step 7: Add CO2 Cartridge, and GO! Step 8: Ask Questions!.
What is the best design for a CO2 car?
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 are CO2 cars 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.
What tools are needed to make a CO2 dragster?
The kit includes everything you require to craft 50 Balsa Wood CO2 Dragsters including the CO2 cartridges and student workbooks plus an array of teaching resources and 4 Dragster paint stands. Assembly requires a drill, coping saw, wood file or rasp, ruler, scissors, finish, and a race system (not included).
What is the best length for a CO2 car?
You need to have at least 60 feet without any obstructions. Any shorter distance than this, and the cars will destroy themselves upon finishing a race. The optimum track length is 66 feet (20 Meters), which is in scale with real dragstrip lengths of a quarter mile.
What makes CO2 cars go 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.
How do you start a CO2 car?
In the launcher, a homemade firing mechanism made from a trim nail, two bolts, two springs and a 1 1/2″ wide x 3/8″ thick short strip of hardwood. 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.
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 fast do c02 cars 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 is a shell CO2 car?
Shell Cars – the wheels hidden. inside the body. EXAMPLES OF DRAGSTER SHAPES AND STYLES. Rail Cars – the wheels outside the body. Shell Reveal – the wheels inside.
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 is drag on a CO2 car?
Drag: Here’s where aerodynamics come into play. As an object moves through the air, it is met with air resistance as speeds increase. This air resistance pushes against your CO2 car and prevents it from going as fast as it could in a vacuum.
What is the most aerodynamic car?
The electric Mercedes EQS is the world’s most aerodynamic production car. Its 0.20 drag coefficient beats the Tesla Model S and Lucid Air. The cab-forward design isn’t just for good looks.
What is the average mass of a CO2 car dragster including the CO2 cartridge?
The average mass of a CO2 dragster is about 50 grams, but we also need to include the mass of the charger – about 25 grams empty. So our total mass is 75 grams, or 0.075 kilograms. If force (F) equals 4.67 Newtons and time (t) equals 0.45 seconds, then the maximum velocity in meters per second is calculated as follows.
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 points of a CO2 car will create friction?
On a CO2 car, friction occurs primarily in three places: between the wheels and the ground, between the axles and the car body, and between the eye-hook and the fish line track.
How do you reduce drag on a car?
Adjust the front fascia and air dam to reduce drag under the vehicle. Add side skirts. Tune the deck height, length and edge radius.You can reduce your vehicle’s aerodynamics by: Lifting it — “an inch of increased ride height degrades the coefficient of drag by about 10 drag counts [. Adding wider tires.
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 do you reduce drag on a co2 car?
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.
Is there a supersonic car?
The Bloodhound supersonic car that was built to break the land speed record is up for sale. Bloodhound became one of the fastest cars in history during trials in the Kalahari desert in 2019. But it needs the addition of a rocket motor to break the all-time record speed of 763mph (1,228km/h).
How does downforce help a v8 Supercar or Nascar race?
It basically states that air pressure moving over a race car’s various surfaces creates “downforce” or increased weight. And while downforce increases tire grip and cornering speeds, there’s a significant tradeoff — greater downforce also increases drag, which reduces straightaway speeds [source: NASCAR.com].
