What is the best design for a CO2 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 makes a good CO2 dragster?

There’s more science than you might think to designing a 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 is the best shape for a CO2 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 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 are restrictions and specifications for the CO2 dragster?

(See Specifications Page) All dragsters must have four wheels (2 Front, 2 Rear) Wheels must be made entirely from plastic with the exception of the Engineering and Technology students and teachers divisions. Races will be over 20 metres unless deemed otherwise by the race coordinator.

What is the most aerodynamic shape?

The most aerodynamically-efficient shape for a vehicle is, in theory, a teardrop. A smooth shape minimises drag and the profile, if correctly configured, keeps airflow attached to the surface rather than breaking free and causing turbulence.

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.

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 car in the world?

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 fast can a CO2 dragster go?

CO2 Dragsters- ‘probably the most popular workshop’

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.

How are CO2 dragsters 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.

How do you start a CO2 car?

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. Rocket cars need long, smooth flat tracks to run. With this quick system, any school hallway will do. Give yourself about 60 feet for it to work.

How long is a CO2 car track?

CO2 dragsters are cars used as miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a typically 60 feet (18 metres) track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, and aerodynamics.

What is the maximum length of a CO2 dragster?

PRODUCTION SPECIFICATIONS MAX
Dragster Body
A. Dragster body length 305 mm
B. Dragster body height at rear with wheels 75 mm
C. Dragster body mass / weight with wheels 170 g

What is the law that explains how CO2 dragsters are propelled?

Sir Isaac Newton’s third law of motion states that for every action (or force) there is an equal reaction (or opposing force) in the opposite direction. CO2 cars are propelled by carbon dioxide rapidly escaping from the cartridge. … The reaction part of Newton’s law is fulfilled by the car’s movement.

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.
