Design Brief- CO2 Race Cars
Problem: You must design, build and race a wooden CO2 powered dragster. You will follow specifications and limits to think up a fast car. The class will compete amongst itself to find a champion. You will research "rail, shell and hybrid" car examples found on the internet.
Using Pro/D CAD software, you will produce an individual Design Portfolio containing:
a Top and Side View Rough Sketch,
a Pro/D CAD Design file- .des
a Pro/D CAD 3 View Drawing Blueprint- .dra
a Pro/D artist's rendering- .alb
Pro/D construction templates- .dra
After the design phase, you will build your own car, following your design and the specs/constraints. You will use the wood shop, and pine wood to fabricate your own dragster. Lastly, you will create a "Brag Sheet" webpage showing off your car's speed and times acquired during testing, with edited or animated pictures of your dragster compared to your original Album rendering.
4. Select which one you want to design. Make a Rough Sketch showing the Front (side) and Top Views
5. CO2 Racer Design Tutorial, and produce the following:
a. .des file of your car design with assembled wheels
b. A full size .dra file of the side view and top view of your racer. This will be used to cut out the shape on wood.
c. A MultiView w/ pictorial .dra file printed to scale. It will include a title block with design team information.
d. A rendered .alb file of the design. Print on color printer.
For grading, you need to individual files for:
1 Thumbnail Sketch sheet
1 Rough sketch- top and side
1 .des file Car Assembly complete w/wheels
1 .dra multi view drawing with pictorial
1 .dra full size building template drawing of the top and side views
1 .alb rendering of the design car assembly
1 raced wooden dragster
1 completed Average Speed Worksheet
1 "Brag Sheet" Web Page, published to internet
