Propeller Configuration

Configuration 1                               Configuration 2

Configuration 3                              Configuration 4

The 4 pictures above depict the configurations of our propellers, which were used for testing. The main differences between these designs were whether the propellers were perpendicular vs. parallel as well as whether the blades were facing inward or outward. When these designs were tested, it was found that design 2 traveled the greatest distance, but design 4 was the most reliable owing to the fact that it traveled the same distance forward and backward. Because the vehicle must travel in both directions during the final process, the team concluded that design 4 would be used in the AEV. The graphs of power vs. time as well as power vs. distance are included below.
