What is the best shape for a CO2 car?
What is the best 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.
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 a CO2 car go faster?
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 is the most important factor in a CO2 dragster?
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 c02 car?
On the 15th October 1997, at Black Rock, Nevada USA, Andy Green piloted the Trust SSC (SuperSonic Car) and achieved what was previously thought impossible. He travelled at a speed of 1,227.985 km/h (Mach 1.020) and broke the sound barrier.
How long should a CO2 Dragster be?
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 are important qualities to consider when designing a CO2?
Designing a CO2 Racer some combination of the two? If you’re in it for the speed, know that the following design factors have an enormous impact on performance: weight — the lighter, the better; aerodynamics — you want your car to cheat the wind; and rolling resistance — less is more!
What is the most aerodynamic shape in the world?
For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has a rounded nose that tapers as it moves backward, forming a narrow, yet rounded tail, which gradually brings the air around the object back together instead of creating eddy currents.
What’s the best shape for a pinewood derby car?
But aerodynamics rule the day, and the best shape is a simple wedge. Just like a spoiler on the rear of a sports car, the wedge shape allows as much air to flow over the top of the car without hinderance while keeping the car pinned to the track. Our wedge tapers from 5/16-in. to 7/8-in.

How do you start a pinewood derby car?
Most derby cars are designed so they don’t start until the starting pin fully drops. But there’s a simple way to let the car start inching forward while the pin is moving, giving you a head start. Unfold a paper clip, making it a three-sided rectangle.
