Team Vision for System-Level Design Phase

During the Systems Design Phase, the team will generate several different concepts in addition to the shop air concept as originally given by our customer. We will either prove that our customer's concept is the best possible option for the task, or we will have generated a superior concept and will need to discuss both options with our customer before preceding to the subsystem design level. These concepts will also be benchmarked against other solutions currently on the market if any exist. In addition to overall system concept generation, a preliminary feasibility analysis will be executed in order to ensure that the given task of copying the 5 Hz compressor pressure curve will be possible.

The overall system does not compete with existing bench marked designs. Only subsystems can be developed using currently accessible products or designs. The previous teams pressure vessel has passed our preliminary feasibility studies.

The team planned to generate designs and concepts for achieving the goals presented by the problem definition. Additional development and analysis of these concepts is necessary to adequately decide on the best system. The team accomplished the specified goals and have successfully determined a system concept to move forward with. The foundation of a preliminary detailed design has been set.
