Performance Test 1

The team was supposed to achieve three primary testing goals for Performance Test 1. The first one was to offer a secondary design of AEV which is different from the original one. The second was to collect lab data from Performance Test 1, this was for providing necessary data to make comparison between the original design and the secondary one. The third goal was to create the preliminary code for AEV which could complete the entire mission without concerns about the energy consumption.

The team completed the first half of the mission and successfully drove the AEV to the cargo site. According to the Figure 3, there are two major phases in this test. The first phase began at 0 and ended at 16.11 s. The AEV accelerated from power input of 0% to 25%, and the AEV finally maintained an average power input of 6.22 Watts. The second phase began at around 26.11 s. The acceleration process was all the same as the first phase, and AEV finally stopped right before the cargo at 33.10 s.

Figure 5: Power V.S. Time for Secondary Design

Figure 5 reveals the power input v.s. time of the secondary design. Because of the different propeller configuration, there was no need for team to reverse the propellers before testing. And according to the plot, the actual power of secondary design when power input was 25% was less than the original design. This could be attributed to the propeller configuration system efficiency. Overall, the secondary design performed better than the original design, it spent less time, and consumed less energy. Therefore, the team decided to keep the secondary design for the following performance tests.
