What are the subsystems in automobiles?
The CO2 Dragster Challenge is simple in context. Your task is to build a scale model dragster that is powered by a CO2 canister and race it against your peers. Fastest car wins! Since the CO2 cartridges contain an equal amount of gas being released at the same speeds, the car that wins the race is the one that is the lightest and most aerodynamic. Think of it as a drag race between two cars with the same engine but different bodies.
There is a system here. A system is a collection of independent components that work together to achieve something. All transportation vehicles work using a system that is comprised of power, suspension, guidance, control and structure subsystems. Think about it...this holds true for a bulldozer and a Ferrari....and our CO2 dragsters.
You will follow the design process outlined in the graphic. This process would be familiar to all designer, engineers, IT professionals and, of course, Design Technology students the world over.
You will complete each of the 4 stages and up-load them individually to Compass. You can improve your work after teacher feedback but you must let your teacher know so that your work can be re graded.
