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 can drag be reduced for the CO2 vehicle?
Aerodynamic drag reduction can be achieved through detailed wind tunnel design work and does not necessarily require an increase in vehicle production costs. For heavy goods vehicles, low rolling resistance tyres could reduce CO2 by 5% at no additional cost.
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 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 do f1 cars reduce drag?
Endplate Design
The endplates have 5-10 times more effect than most other parts. They control the flow of air around the Formula One car by redirecting the airflow around the tires. This minimizes the overall drag resistance produced and facilitates the airflow to continue back to the side pods and the car floor.
How can we improve coefficient drag for cars?
Side mirrors both increase the frontal area of the vehicle and increase the coefficient of drag since they protrude from the side of the vehicle. In order to decrease the impact that side mirrors have on the drag of the vehicle the side mirrors can be replaced with smaller mirrors or mirrors with a different shape.
Does lowering car reduce drag?
Lowered vehicles are more aerodynamic. There's less air hitting the wheels and tires (that are not streamlined shapes). This makes these cars faster. ... BUT, lowering a car too much will actually increase wind drag.
What is drag reduction?
Drag reduction is a physical phenomenon that causes friction to be reduced and fluid flow to be increased. Chemicals that reduce drag are known as drag-reducing agents (DRA). Several polymeric compounds can reduce the wall shear stress of flowing liquids at low concentrations.
How do diffusers reduce drag?
The diffuser acts as an expansion chamber to manage the air as it exits from underneath the car and reintegrates it with higher-pressure ambient air. Smoothing this transition reduces turbulence and drag in the car's wake and improves airflow under the car.
Why do designers try to Minimise drag?
Minimizing drag can save huge amounts of fuel
Thus, the more drag your ride produces, the more fuel it will need to use in order to overcome this force. Some sleek design is fundamental for fuel economy. Take the Tesla model S as an example.
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 car 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.
How do you make a CO2 dragster go 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 do CO2 cars work?
CO2 cars are propelled by carbon dioxide rapidly escaping from a small container called a cartridge. The cartridge is positioned in the car so that the escaping gas moves in a rearward direction. The rearward force of the escaping gas is the initial action described by Newton.
