Car Aero: How Aerodynamics Affect a Car

CSEF · 2014 Aerodynamics/ Hydrodynamics (Junior Division Only)

Jaylan C. Catacutan · Vanden High School, Fairfield, Solano County

Overview

Objectives/Goals My goal is to find how the shape and the edges of a car affect top speed, gas mileage, handling and acceleration. Methods/Materials I used hobby boards, fans and acrylic to create a wind tunnel and find how air reacts to a car in motion. I used a variety of model cars ranging from 1:24 scale to 1:18 scale. Results After testing, i learned that smooth and subtle edges on a car helps increase gas mileage, acceleration, speed and handling. Conclusions/Discussion Overall, I have concluded that smooth and subtle lines helps a car all together, i also learnd that spoilers on the rear end of the car help reduce resistance of air on the car for better speed.

Summary statement

My project is about the effect of aerodynamics, wind resistance and air odrag on a car

Help received

Dad helped cut materials for the wind tunnel assembly
