Functional DecompositionThe functional decomposition decomposes our top level function of "Demonstrating Microgravity Concepts" into solutions independent categories.

Morph ChartThe bottom level, solution independent categories of the function decomposition are now extracted and placed into a chart format. At this point we introduce various solution ideas for each component. The image below depicts a few examples of this process.

Systems ArchitectureIn order to develop an original solution path we utilized Pugh's Matrix to compare an array of drop tower designs, based on various practical combinations from our 1st iteration Morph Chart. This process was helpful in understanding how different components would interact with one another. To view the Pugh Matrix iterations click the following link. Pugh's Matrix
The System Architectural Components can be seen in detail by downloading the following link: System Architecture.
Concept DesignBased on the results form our Pugh's Matrix and subsequent iterations of concept designs, we are able to select a preliminary concept design. To view all developed concept designs, click the following link. Concept Designs
Risk AssessmentIdentifying potential risks is an important part of the design process. It can save a lot of time and frustration during the testing phase of MSD II if we can prevent any major problems in advance. We will focus primarily on technical risks in this section.

Test PlanBased on our chosen concept design and risk assessment we can develop early ideas of testing. Our test plan consists of 2 phase: Subsystem Tests and Fully Integrated System Tests. The subsystem test will ensure that each component operates as expected and the team is familiar with the operating procedures. The fully integrated tests will ensure that the drop tower runs according to plan. These tests will be used to develop the designed experiments and the operating procedures.
Detailed Tests Plans includes the following: description, required materials, procedure, results, specifications, comparisons & comments
