How can I make my CO2 dragster faster?
Simply put, the less weight your dragster has, the faster it will go. This is the most important factor that will figure into your design. Keep it light! Thrust: The gas escaping from the CO2 cartridge in the car.
What is the fastest CO2 dragster?
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 is the most aerodynamic shape 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. This equation has to do with how much weight is over the front and rear of the vehicle.
How are CO2 dragster made?
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 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 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.
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.
Who holds the current land speed record?
The current holder of the Outright World Land Speed Record is ThrustSSC driven by Andy Green, a twin turbofan jet-powered car which achieved 763.035 mph – 1227.985 km/h – over one mile in October 1997. This is the first supersonic record as it exceeded the sound barrier at Mach 1.016.
What makes a fast c02 car?
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 reduce drag on a CO2 dragster?
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.
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 cars get CO2?
A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.
How do you make a CO2 car race?
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!.
How much does a CO2 dragster weigh?
It weighs 3600 pounds. Fuel consumption is about 40 gallons per minute. Your dragster uses a CO2 cartridge for power. The cartridge contains CO2 gas under pressure.
Can a dragster work with less than 4 wheels?
A dragster must have exactly four (4) wheels, each of which separately must meet the regulations in W2 and W3 below. All four wheels must touch the racing surface at the same time. All wheels must roll.
Why do drag racers use CO2?
CO2 puts the pressure on the wastegate to hold the valve closed as soon as or before it is actually needed. It reduces SO MUCH time when trying to build boost or spool a turbo engine. This saves not only time but puts less stress and reduces temperature to your torque converter and transmission!Aug 23, 2020.
How much force does it take to puncture a CO2 cartridge?
CO2 liquefies at a pressure of 70 bar at 2500 C.
Can CO2 cartridges explode?
Immediately the heat in the air around the cartridge starts warming it. And when it does, the warmth causes some of the liquid CO2 to boil back into a gas. Past 87.9°, the gas pressure climbs with the temperature and the cartridge can actually explode if it gets too hot.
What are CO2 cartridges made of?
Basically, CO2 cartridges are little cans filled with pressurized carbon dioxide gas. Most are pretty small in size (just about the size of your thumb), making them incredibly easy to store and stash away so you always have a few cartridges handy.
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.
