Team Vision for System-Level Design Phase

Our team's goal for the System Design Review phase was to brainstorm different possibilities for each engine subsystem and then select the superior designs based on certain attributes. We first created a Functional Decomposition to make sure we captured all the functions that our engine needs to perform. We then researched different hybrid engine components that already exist for the purpose of benchmarking in order to get a better idea of what already exists and to try to learn from the mistakes of others. Based on the information we found, we were able to create a list of preliminary system design options. From here, we were able to use a Pugh Chart to select the superior concepts and then determine how feasible each concept would be. We also assessed risks associated with manufacturing and testing each system.
