CO2 DRAGSTER :

We all love to race and imagine driving a car faster than any one can. I don’t know how many of us can do it right now but of course we can make our little dragster race like crazy :)






DRAGSTER: -
CO2 Dragsters are miniature cars used for racing and powered by carbon dioxide cartridge. They are used by students to analyze various mechanical and aerodynamics design and effect on moving body. In schools students are often seen competing with one another and improving their car designs.






Things to be considered while designing:-
1. Painting your car will reduce aerodynamic friction.
2. Lubrication of the axels can reduce friction. Use light but effective lubricants. Heavy and greasy lubes may not be a good stuff for lighter moving bodies.
3. The wheel plays a key role here so care must be taken to design the wheel with less ground contact.
4. Avoid unnecessary extensions and ornaments that add weight to your car.
5. The lighter you design your car, the more power will be used out of your CO2 cartridge.
6. Make sure that your drill holes are straight and accurate to reduce extra forces acting on your car.
7. Avoid flat upright surfaces in the front of your car to reduce turbulence.
8. Avoid flat upright surfaces in the back of your car to reduce rear suction.
9. Shield as much air at the bottom of your car to maintain traction.
10. Keep the surface area exposed to oncoming air to a minimum.
11. Place the cartridge parallel to the ground.
12. Axel design is important to reducing friction.
