Transcript of CO2 Car Design Process Final

CO Car Design Process By: Du Vu and Alex Fairbanks We are doing that right now with you guys. :D
So you guys see what we had done and give us advice on how to improve our cars and give us feedback on our work. We made our design in SolidWorks Research and Generate Ideas We researched aerodynamics to discover its fundamentals so we may use it on our car.
We also looked up other car designs to help us come up with a design.
We also checked the previous CO car winners for previous years. Citations Technology Student Association

CO Dragster Design Informaion
-http://www.buechenet.com/tech-ed/dragster/aero-ld.html We had to design and produce a fast CO -powered dragster according to the specifications of the TSA Dragster Design Challenge with certain specified materials. Identify Criteria and Specify Constraints Design must be symmetrical and aesthetically pleasing.
The car should be as light as possible without reducing the structural integrity.
Car aerodynamics should be optimized for the fastest race time.
The car must qualify under the TSA Dragster Competition regulations. TSA Dragster Competition Regulations Brainstorming Communicate Processes and Results Develop a Design Proposal Define a Problem Refine the Design There are several ideas that came to mind after we made the model that we could use to make improvements on our design.
Some errors in the design may occur when we scaled down the car though we fixed the more important errors.
We could had made our car more aerodynamic if we made the back, where the CO tank is, curve inward. What we want with our car-
Curved for less drag (more aerodynamic)
A pretty sleek car for less weight
A car similar to a real dragster 2 2 TSA 2012 1st Place
For High Schools Other designs we saw Explore Possibilities Light Light Light Aerodynamic Aerodynamic Somewhat
Aerodynamic Easily Break
In the middle Structurally
Sound Could Break
if too thin Select an Approach We decided on this approach because it was a simple design that met all of our requirements.
Light
Aerodynamic
Structurally sound THE END. ANY QUESTIONS? Make Model or Prototype Our final design is going to be made out of balsa wood but we first have to make a model to see if it works. We made a model in a 3D Printer. Upcoming Events Test and Evaluate the Design Using Specifications -Friday, November 30, 2012 We are going to test our cars on Friday when we get to race with other students to see who designed the fastest car. THANKSGIVING Winner? Create or Make Solution 2 2 If we make another model then we would implement the addition changes.
If we make the final from the balsa wood then we would do the same as the model.
We still have to wait to see if our first model works before we can move on. 2
