During lab 5, the team learned about the different orientation that the propeller and motors can have. The purpose of this is to find which orientation will have the highest efficiency. For this lab, there will be two different size blades along with two different ways that a blade can be configured. Between the two different orientation and two different blade diameters, there will be a total of four different set up that data will be collected from.
The purpose of this lab was to collect data about different types of propellers using a wind tunnel. The data was used to analyze to see what propeller would be the most efficient for the teams AEV. This lab is important because the team quantifies the characteristics of the propellers. This allows the team to have a better understanding of their design, and overall how to build their AEV with more efficiency.
Overall it was found that the 3030 Puller blade has the highest propulsion efficiency for the smallest advanced ratio. This means that the blade has the most efficiency for a lower propellor speed, which is what is desired for an efficient AEV. The team will likely use the 3030 Puller blade in the AEV design in order to be the most efficient. Shown below are the graphs from the collected data that was used in order to determine this result
