Objectives/Goals Can a functional wind tunnel be constructed that allows the aerodynamic testing of automotive models? Will this testing match known aerodynamic values for modern vehicles? Can a model be constructed that is aerodynamically superior? What design features would this model incorporate? Methods/Materials Construct wind tunnel using plans from the internet. Build five model cars out of styrofoam blocks. Test each car ten times to determine aerodynamic force measured in ounces on a postal scale. Compare these values to known aerodynamic coefficients. Use derived information to begin independent testing of aerodynamic features. Cut and shape styrofoam blocks in pursuit of aerodynamically superior body shape. Analyze the effects of various features. Results The aerodynamic forces measured were similar to the results I hypothesized. The cars in order of least force to greatest drag force were: EV1, Toyota 2000GT, Porsche 911, Chevrolet Z28, and Hummer H2. ...
