The Process

7

Lab 1: Arduino Programming BasicsAccomplishments:

1. Learned the basic hardware configuration of the AEV2. Learned how to program the arduino

Takeaways:

1. Problems encountered during this lab allowed further understanding of the hardware and programming of the AEV

2. This lab was the foundation for all further labs as all future labs relied on the knowledge gained in this one

8

Lab 2: Ext. Sensors & Sys. Analysis IAccomplishments:

1. Learned about external hardware components and how to use them for more precise programming of the AEV

2. Used experimental wind tunnel data to gain an understanding of the various propeller configurations possible on the AEV

Takeaways:

1. Exact distances can now be specified for AEV programming2. Pusher config favors higher advance ratio for efficiency, and puller favors

lower advance ratio9

Lab 3: Sys.Analysis II & Design AnalysisAccomplishments:

1. Acquired quantitative data related to the performance of the AEVa. Time, voltage, current, energy, distance, etc...

2. Establishment of a design analysis tool using MATLABb. Analysed quantitative characteristics and data to build visual representations

Takeaways:

1. The design analysis tool helps gain a better understanding of the physical processes utilized in the AEV

2. Power v. time or distance phase plots can be used optimize AEV designs and arduino codes

10

Lab 4: Creative Design ThinkingAccomplishments:

1. Individually brainstormed ideas for AEV configuration2. Carefully discussed pros and cons of each and provided the basis for formal

design selection in lab 5

Takeaways:

1. Elaborate designs were considered but the most practical design was found to be more favorable

2. Orthographic drawings are an effective means to create quality designs

11

Lab 5Accomplishments:

1. Come up with a concept screening scoresheet.2. Design a concept scoring matrix.

Takeaways :

1. Decided upon a list of success criterias that would contribute to the outcome of the AEV.

2. Determined the appropriate weightage for each of the success criteria.
