What makes a successful C02 dragster?
Mass: Obviously, this is how large and heavy the car is. 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. This air resistance pushes against your CO2 car and prevents it from going as fast as it could in a vacuum.
What makes a good CO2 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.
What are the steps to making a CO2 car?
- 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 makes a dragster aerodynamic?
Designing the Body of Dragster Shell dragsters are cars in which the body, including the wheels, are covered by a shell. Using a shell helps reduce the aerodynamic drag to a great extent. In a rail design, the wheel and other parts of the dragster are exposed, which naturally increases the drag.
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 most aerodynamic 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 is the fastest dragster in the world?
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.
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.
What does CO2 do to a dragster?
First, it helps to shave weight by removing material. Secondly, it can help minimize drag by reducing the size of the drag vacuum pocket behind the car. Mass: the less weight your dragster has, the faster it will go. Thrust: The gas escaping from the CO2 cartridge in the car.
Where to put CO2 cartridge in race car?
Add your CO2 cartridge into the hole at the back of your car. Make sure the hole is not punctured in any way, or the cartridge will explode. Lastly, add your fish hooks. These are encouraged, but necessary, for your car. If you are running a race in a track that has a string for the car to follow, these are perfect for staying on the string.
Which is the easiest model for a dragster?
1. Rail Car: This design for a dragster miniature has wheels that are externally placed and an extremely narrow chassis. It is one of the easiest models to make. The design is also such that it causes a reduction in the mass of the car, thus increasing speed efficiency.
How do you reduce drag in a car?
The cartridge is positioned in the car so that the escaping gas moves in a rearward direction. Friction: reduce it by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body. Drag: As an object moves through the air, it is met with air resistance as speeds increase.
