How to make a CO2 dragster faster?
It is recommended the car has a sleek surface to reduce the aerodynamic drag. This trick or technique is used quite commonly. However, for the CO2 dragster to be far more effective (speedy), one should think about making the surface like that of a golf ball. A golf ball is marked by presence of small pits over the surface.
How do you reduce the drag of a dragster car?
In a rail design, the wheel and other parts of the dragster are exposed, which naturally increases the drag. It is possible to reduce the aerodynamic drag of CO2 cars by shaping the rear section in a boat-tail form. The axles fitted into dragster cars need to be as short as possible.
What are the advantages and disadvantages of shell dragsters?
The advantage of using rail designs is that they have low mass. However, this benefit can also turn into a disadvantage, since dragsters with such a design have a fragile body. Shell dragsters are cars in which the body, including the wheels, are covered by a shell.
How to cut basswood for Dragster?
After tracing the outline of the cross section of the dragster on basswood, a saw blade should be used for cutting it. Holes need to be drilled at appropriate places for axles. It is necessary avoid painting cars with thick coats; this is because lighter the dragster,...
How can I make my CO2 dragster faster?
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. It is possible to reduce the aerodynamic drag of CO2 cars by shaping the rear section in a boat-tail form.
How do you improve the wheel spin on a CO2 dragster?
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.
What is the most aerodynamic shape for a CO2 car?
Shell cars are bullet-shaped, hollowed-out bodies with the wheels enclosed inside. These are definitely the most aerodynamic of any design, and will usually come to dominate any class into which they are allowed.
How does a CO2 dragster work?
CO2 cars are propelled by carbon dioxide rapidly escaping from the cartridge. The cartridge is positioned in the car so that the escaping gas moves rearward. The rearward force of the escaping gas is the initial action described by Newton. The reaction part of Newton's law is fulfilled by the car's movement.
What 3 things can you do to improve wheel spin?
Here are five things you can do to control your car during a spin-out:Avoid Slamming on the Brakes or Speeding Up. Do not slam on the brakes or speed up when your car starts to spin out. ... Reduce Your Speed. ... Keep the Steering Wheel Straight. ... Maintain Firm Pressure on the Brake Pedal. ... Pull Off to the Side of the Road.
How do you make a CO2 dragster more aerodynamic?
Three Things You Can Do to Reduce Drag in CO2 CarsGolf 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 is the fastest CO2 car?
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.
Why do dragsters have bigger rear tires?
After the car launches, inertia grows the tire to as much as 38 inches in diameter, simultaneously lengthening and narrowing the contact patch. This effectively lets the final-drive ratio grow taller for higher speeds and reduces rolling resistance as the vehicle hits terminal velocity.
How fast can a CO2 dragster go?
70 miles per hourThey'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)!

And lowers the fins as.
What is the best shape for a dragster?
The dragsters needs to be able to cut through a wall of air. This will make acceleration easier. Teardrop shape allows air to flow over the body of a car. The less friction of the wheels on the axis, the faster the car will move.
How does weight affect a CO2 car?
the heavier a vehicle is, the greater its fuel consumption and CO2 emissions. Therefore, reducing mass is an effective way to reduce a vehicle's emissions.
